Do not mix copper cable and fiber cable in the same ducts or trays. It can be helpful to allow movement of patch panels inside the cabinet with service loops for both fiber and copper, if growth is expected. AT&T Fiber℠ self-installation guide. The pulling eye (and associated cable netting) will protect the pre-terminated ends during the pull. These breakout lengths can be staggered to plug into specific ports, patch panels, and/or hardware. Fiber optic cables have Kevlar aramid yarn or a fiberglass rod as their strength member. Never directly pull on the fiber itself. If the trunk does plug into two separate enclosures, plug the trunk connectors into the specified ports first, then secure the furcation or breakout point. The number of 90 degree turns on a pull shall not exceed 6 for aerial cables and 4 for underground cable-in-conduit. e. Do not discard excess cable from the installation, but store it for future needs in restoration if the cable plant is damaged. Cap off or seal the ends of cables with water blocking gel or grease. These checks should be performed as-received/before installation, after installation, after splicing, and after connector installation. Ensure that the pulling eye and swivel assembly have no sharp edges and can easily fit through all conduits, pull boxes, and cable trays. Proper technique is placing or laying a cable in a cable tray or raceway. Follow the following step by step guide for installation of fiber optic cable: Step One. Leave the protective thermal wrap … Feb 27, 2016, Multimode Fiber and Multimode Fiber Optic Cable Tutorial Install a cable in locations in which the temperature range imposed is within the temperature operating range. Violation of the temperature operating range can result in excessively high attenuation. Indoor fiber cables and outdoor fiber cables generally classify fiber optic cables. In outdoor installations, a common practice of 2.5 foot sag for 150 foot span is good for thermal expansion and contraction. The installation partner should show modified cable routes of all backbone cables, backbone cable pathways, and cable trunks. The minimum crew should have one person monitoring the pulling equipment, one monitoring the supply reel, and one coordinating all involved in the installation. ACCEPTABLE. Careful cable placement facilitates access to transceivers and ports both in active equipment and patch panels. For direct burial installations, the cable should lie flat in a trench, free of any large stones or boulders that may deform the cable. Cleaning fiber optic transceivers. Fiber optic cables shall be identified in such a way to distinquish these cables from wire or coaxial cable. Prior to engineering your cabling design and installing your fiber optic cabling, the CABLExpress architects will request your data center hardware layout design. Never exceed the cable bend radius.

Even though your fiber connector will have a protective cap of some kind on it, any cover can attract dust as it moves through the air to settle on the tip. Optionally, the jacket can be tied into a tight knot before pulling. There are only two per trunk, one per side. The two most common outdoor fiber optic cable installations in Ohio are pole-line aerial … Failing to test fiber cabling after it is delivered is a common mistake made by installers. In medium fiber-count cables (6 to 24 fibers), the connectors must be staggered when installed to reduce the diameter of the pulling grip. For extensive work with fiber optics, safety glasses with IR filter is recommended. It could also be located in the basement or in the garage. Installing Fiber Optic Cable. The cable weight in an unsupported vertical rise shall be less than the specified long term operating load. When all the cable is placed in this pattern, the pattern is lifted and flipped over, so that the loose end is on top. Trunks are custom-built and cannot be returned. It’s true that fiber optic cable, based on optical technology to carry information between two points, have become increasingly important in fiber optic Fiber Optic Glossary Conduit runs should be limited to 100 feet, with no more than two 90-degree bends between pull points or boxes. If installation will be delayed, store your purchased cabling products in their original packaging in a safe area where they will not be damaged or misplaced. Properly train and instruct the people who will do the installation. The design’s intent is to minimize future errors due to snags, awkward cable access, slack, and unprotected connections in trafficked areas. This map should include the cabinet placements, patch panels, hardware, port-counts, trunking locations and power access connection points. Underground conduits, if newly installed, should be a minimum size of between 1.5″ to 2″. There is also a chance that some human hands have touched it, or a particulate has scratched it.

Phone: 510-319-9878 Whether service loops will be managed on the sides of a cabinet vertically or at a specific rack unit(s) horizontally is determined by the data center operator. After the fiber optic cable is installed into a duct or innerduct, end plugs should be installed to provide an effective water seal. Any and all changes from the original design drawings in the SOW should be in the document. The ducts and innerducts should be kept free of debris and maintained watertight at all times. Communicate along the path of installation. www.cablexpress.com. Pushing can result in violation of the bend radius. Step 1: Connect the AT&T Fiber℠ Service Box. A fiber optic cable should be tested three separate times during an installation: on the reel, the splicing test, and the final acceptance test. Midspan access of fibers in buffer tubes: To minimize fiber damage, use a Midspan Access Tool to open the buffer tube such as a Corning OFT-000. Identification methods typically used are color-coding, labeling/marking, etc. Your label numbering scheme should match the TIA-606-C published standards for all jumpers and patch cords, labeled by: Using the standard provides consistency and a format that should be recognizable to installers working in your data center. Also, avoid excessive twisting or stress on pre-terminated cables during installation. In order to get an accurate measurement of the fiber optic cable, the loss of the two reference cable has to be “zeroed” out (0 dB) or subtracted from the total loss. Keep in mind that “pinching” the fiber optic cable also damages the glass, thereby ruining performance. Rope off or otherwise isolate the area of cable installation to prevent access to unauthorized or untrained personnel. Typically this is when the ambient air temperature exceeds 80˚F. Excessive stress can break and/or damage an assembly, causing it to improperly pass network traffic. The furcation point is designed for this, as it has a metal sleeve to protect the fiber. Take inventory of all components received onsite to match to the bill of materials provided with the design. When making a connection, the connector should attach to the adapter smoothly. Feb 27, 2016, Fiber Optic Patch Cables Tutorial If cables are present in ducts through which the fiber cable is to be pulled, the existing cable types should be identified and the owner of the cable called to inform him of the action, and to identify any safety concerns. Without this sectionalization, additional cable pulls can entangle an operating cable and could cause an interruption in service. This can be accomplished by weaving the strength member into the fingers of the grip, and then taping it together. The coil can get deep quickly and a figure 8 will provide more room. When installing fiber optic jumper cables and copper patch cords from the patch panel to active ports within the same cabinet, use a combination of horizontal and vertical cable management to route cables from the left side of the patch panel to left side active ports, and the right side of the patch panel to right side active ports. During cable placement, it is really crucial that the cable not be bent to a smaller radius. 50/125 μm FX2000 jumpers for a 50/125 μm FX2000 optical fiber system) and shall be one to five meters long. Never install a fibre optic cable if temperature is below –5°C (Be aware that in cold environment the cable jackets are stiffer and more sensitive to bending and pulling. Check continuity and attenuation. When an outdoor rated fiber cable enters a building, it should be spliced to an indoor-type fiber cable within 50 feet from the cable entrance to meet NEC code. For longer lengths, label your trunk cables at both ends with length, origination, and destination information. You should always clean the connector and adapter before plugging them in. DO NOT rotate back-and-forth or round-and-round because this could grind debris into the transceiver. Always have a pull-eye added to a cable longer than 100 feet. Grounding: Cable with metallic components shall follow the bonding and grounding requirements of the customer and local or national codes. Anticipate obstructions. These will harm the fibers, maybe immediately, maybe not for a few years, but you will harm them and the cable must be removed and thrown away! Observe the temperature operating range. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Patch cords are interconnect cables, which means they should be deployed within racks or cabinets and should not be deployed in ladder racks. Optional pulling eyes are highly recommended. Stretching of the rope is undesirable for several reasons including that it makes for a very unstable pull, and takes away control from those doing the pulling. All Orders Get 5% Cash Reward. Use an air compressor with a minimum of 375 cfm. Know and observe the maximum vertical rise distance limit. All vertical cable must be secured at the top of the run. A split mesh grip is recommended to secure the cable. Instead, you’ll need to connect your phone company and a technician will do the work.The fiber optic cables will end up in an optical network terminal on the side of your house. Basic guidelines that can be applied to any type of cable installation are as follows: • Conduct a thorough site survey prior to cable placement. Number of 90 degree turns. Plan the Installation. Attach cables with plastic clamps having large surface areas. After pulling, the knot should be cut off. Care should be taken to use the correct insert size. Do not use a blade to slit the mesh. Do not let the connector tough any surface once the duct cap has been removed. The strength member should be attached independently. Special fiber optic blocks should be used on all turns or angles. Before the start of any cable pull, all ducts and cable vaults should be carefully inspected for damage or deterioration, and to address any safety concerns. Proper cable lubrication is designed to reduce the tension on the fiber optic cable. Test results should be provided both in soft and hard copy. On runs over 100m, use proper lubricants and pull from the middle out to both ends. Divide long pulls into several shorter pulls, using the figure 8 technique for storing cable at the intermediate locations. Indoors fiber optic cable installation can either be directly or using conduits or fiber optic trays. Ensure that the proper cable length has been installed before cutting off excess cable. Conduit Installations General Information: Try to design the conduit run with a few bends as possible. Maintain proper clearance between the fiber optic cable and power cable at all times. Properly attach the pulling eye and swivel to the cable. Cables should be tested after shipping. Intermediate cable attachment points however are recommended for optimum performance. The pulling tape should have a rating for greater than maximum anticipated pulling tension. Monitor the supply reel. The FOA and NECA (National Electrical Contractors Association) in 2001 cooperated to develop the first ANSI standard (American National Standard) covering the installation of fiber optic cable plants. For fiber optic cable, use horizontal finger style with front cover cable managers in a 1U or 2U footprint. Use plenum rated cable where it is mandated, etc., etc. Fiber optic cable installation is not an easy task. On really long runs, pull from the middle out to both ends.

Using it outside these parameters can lead to damage or pressure on the small fiber jumper cables, which could potentially increase loss or damage the link. Future plans for change will be discussed, as well as the bandwidth required. Indoor cables can be installed directly, but you might consider putting them inside innerduct. attaching the fiber optic cable that needs to be tested between two reference cables, one attached to the source and one to the power meter. For loose tube and ribbon cable this is typically specified for an installation temperature of -30C to +75C. Fibers from the cardboard packaging can become airborne and damage the hardware inside the data center. CABLExpress manufactures high-performance data center cabling infrastructure products. Personnel involved in Optical fiber cable installation must be aware of all the applicable Occupational and Health safety regulations, the NESC and local regulations along with the company safety practices. It is extremely important to take an accurate measurement when planning an order for a custom pre-terminated fiber optic cable assembly. Cable clamps should be installed manually with gentle pressure. These data logs should include both insertion loss measurement and OTDR measurements. Consider the route to determine the maximum blowing distance. Pull, do not push cables. Use the location layout to match any specific pre-engineered staggers to the applicable equipment into which they are being plugged. Transmission performance depends on several characteristics: Testing results directly after installation: 5404 South Bay Road Fibers and buffer tubes do not have sufficient strength to resist breakage due to normal handling of copper cables. Maintain proper air flow to “blow” the cable verses “pushing” the cable. They can interfere with access to the cabled hardware units. Never exceed the maximum pulling load rating. A set up with multiple blowing machines may be required. The reason is that the excess length of fiber in the buffer tube and the ability of fiber to move from low stress region to higher stress region. The electric spark generated by a fusion splicer can cause an explosion when flammable gases are present. If the cable is too short, don’t try to stretch it! Use plastic bushings on conduit ends to avoid damage to the cable during the pull. 4.1 Aerial fiber-optic cable plant must be stiff enough to keep the fiber stress within acceptable limits under the loads given in Table B. Safety Precautions 1.1 Confined Space Precaution 1.2 Lead Exposure Warning 1.3 Cable Handling Precautions Corning Optical Communications cable specification sheets are available which list the maximum tensile load for various cable types. The cables are special in many ways. After the fiber optic cable is installed into a duct or innerduct, end plugs should be installed to provide an effective water seal. Such marking will alert electricians to the nature of the cable. Record all required fiber optic facility details, including proper route drawings, fiber assignments, loss readings, OTDR traces, etc. Email: sales@foscoconnect.com, 101 Guidelines for Fiber Optic Cable Installation, Fiber optic cleaning - fiber connector cleaner, Multimode Fiber and Multimode Fiber Optic Cable Tutorial, Single Mode Fiber - Single Mode Fiber Optic Cable. This will ensure you do not damage the assembly when pulling on the fiber optic “legs.”. Loop vertically installed loose tube cables. Try to design the conduit run with a few bends as possible. Familiarizing yourselfwith Standard 301 is a smart step to avoid such problems.Up until a little over a year ago an installation standard for optical cable didn't exist. The architects will use this detail and additional information gathered, to build the cabling infrastructure design. Cables in vertical installations that are longer than the vertical rise limit must be tied off at distances less than this limit. The layout should include the destinations of the fiber trunk assemblies, referred to as “Trunking Locations.”. It’s from here that you’ll run the fiber optical lines into your house for phone, Internet and TV. Do not use a back and forth scrubbing action. Fusion splices should therefore not be used in vaults. The following fiber cable installation guidelines are recommended as best practices pre-, post-, and during installation of CABLExpress Skinny-Trunk® products in accordance with the TIA-942 Data Center Standard and our own experience! Your manufacturer’s specification sheet should be consulted for specifics. Protective caps should be left on until immediately prior to cable installation. Install vertical, unfilled, loose tube cables with loops to prevent the fiber from slipping to the bottom of a vertical run. Consider wide body cabinets (wider than 24 inches) along with vertical cable managers (4”, 6” or 12” wide) for core cabinets, main patch cabinets, or cross-connect cabinets. If there are too many bends in the run then you may consider installing junction boxes in lieu of bends. Warranties don’t cover mishandling of cabling. Never exceed the maximum pulling load rating. Identify cable locations with surface markers. Monitoring the supply reel during installation is necessary to prevent violation of minimum bend radius. These custom assemblies cannot be returned unless out of box defective. TIA-606-C documents the official standards for cable colors. Leave cable and fiber service loops everywhere. Bare glass fibers can cause splinters which are very difficult to find and remove. You should pull on the fiber cable strength members only! When working in freezing temperatures, use a lubricant that is designed not to freeze. Do not store cable within the closure or pedestal unless there is enough room to accommodate the minimum specified cable bend radius. Get the cable from the local box to your house. If the run is long, or if you anticipate the possibility of additional future pulls; Then you may want to install a conduit of up to 4″ (or greater). A maximum 40% fill ratio is a good rule of thumb to follow for duct size. Lubricate the cable when installing in conduits. For cables using aramid yarn alone as the strength member, the jacket can be removed to expose the yarn. If you don’t already know someone here, we’re glad you found us and happy to get to know you! We need to install a fibre cable from your street to your property and we want your fibre install to have as little impact on your property as possible. Always roll the cable off the spool instead of spinning it off the spool end. Create a detailed, written plan of installation. If possible, use an automated puller with tension control or at least a breakaway-pulling eye. The person may stop the cable pull from time to time to prepare and apply more lubricant. Fiber optic cables should be placed in their own dedicated ducts or trays. If insertion loss suddenly increases with an adapter or connector, the cause may be dirt. Installation of these cables is different. Segregate or isolate the work area. Poles must be prepared for the installation of the pulleys and the final cable hardware before cable pulling begins. As fiber optic cable is sensitive to excessive pulling, bending and crush forces, much care shall be taken to avoid cable damage during its duct installation. Do not mount service loops in conveyance unless specified in the design. For copper, use horizontal D-ring style cable managers in a 1U or 2U footprint. If possible, use an automated puller with tension control or at least a breakaway pulling eye. Pleasanton, CA 94566 Loose tube cables can be more forgiving of abuse than tight buffer cables. The finalized layout and port counts are critical to an architect’s effective design. Just call us at 800.913.9465 during business hours EST, or fill out the form on this page. Do not rotate the connector when making the connection. Damage to cabling can occur during shipping or installation. Most pre-terminated systems today do not require additional cable added for service loops. Firstly, you should check for the availability of fiber optic network in your area. Look for signs of stress on the cable jacket. Avoid placing cable reels on their sides or subjecting them to shock from dropping. When installing long runs, communicate and monitor along the path of the installation. Failure to follow the same can lead to fatal consequences to them as well as people in the vicinity. Never twist the fiber cable. CABLExpress has pre-engineered staggers for all common hardware types with the intent of creating a tidy, slack-free installation to minimize accidental pulls and create an aesthetically pleasing result. Sign Up Now! If there are too many bends in the run then you may consider installing junction boxes in lieu of bends. The fiber pulling rope or tape should be sequentially marked (foot or meter) for easy identification of distance. We will respond as quickly as possible. For cables using aramid yarn and an fiberglass central member, a pulling grip should be used. Copper trunking is thicker and stiffer than fiber optic trunking. Pulling and reel locations should also be set at corner vaults where possible. A cable shoot/pulley larger than the specified bend radius is recommended to minimize the cable bend at the first and last pulley locations or at any location with a change in direction. Never look into a fiber, cable, or connector unless you know for sure that there is no laser light in the fiber. You don’t want your installer to pull a 200-foot cable through its designed route only to discover the wrong cable or the wrong end was pulled (see more information below in section titled “Don’t Pull Too Hard”). While inconvenient to remove, pull-eyes protect your connections and your warranty. Use cable managers in all new cabling applications. Copper also can have negative performance results from crosstalk when too many strands are bunched together in a bundle or tight space. When installing optical cable, what you don't know could really hurt you or damage your cable. The cable is placed on the ground in a figure 8 pattern. The practice of fiber optic cable installation has become much more common than ever. The swabs should only be used ONCE. Work your way from the back of the cable toward the pull eye, while lifting the mesh upward, away from the cable. Proper training reduces expense through reduction of breakage and excess attenuation. The tip of the fiber connector, where the fiber optic glass protrudes, is the most common area for damage to occur. Putting a twist in the cable can stress the fibers too.
