Do not discard excess cable from the installation, but store it for future needs in restoration if the cable plant is damaged. Cable blowing air cooler. Check the continuity and attenuation of the cable before each operation. Air compressor cooler should be used as recommended by the blower equipment manufacturer. 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. Monitor the supply reel. Do not let the connector tough any surface once the duct cap has been removed. The two most common outdoor fiber optic cable installations in Ohio are pole-line aerial … For copper, use horizontal D-ring style cable managers in a 1U or 2U footprint. The cables are special in many ways. Phone: 510-319-9878 General Guidelines of the Optical Cable Corporation Installation Guide. On long runs, use proper lubricants and make sure they are compatible with the cable jacket. ACCEPTABLE. If there are too many bends in the run then you may consider installing junction boxes in lieu of bends. Typically this is when the ambient air temperature exceeds 80˚F. Make As-Built Data logs. A small amount of slack cable (20-30 feet) can be useful in the event that cable repair or relocation is needed. 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”). Follow the following step by step guide for installation of fiber optic cable: Step One. If this happens, attenuation can increase and fibers eventually break. If your inventory is short, or product is damaged, you will not be able to get replacements overnight. Fiber optic cables should be placed in their own dedicated ducts or trays. Before plugging into a port or patch panel, the installer must inspect the surface of the fiber optic glass end point (ferrule) with a microscope and, if needed, clean the connector with a one-click cleaner. Use only lubricant that is expressly designed for cable pulling. It’s important to match any staggers to the correct equipment. • Develop a cable pulling plan. The practice of fiber optic cable installation has become much more common than ever. Do not use a back and forth scrubbing action. Plan the Installation. The fiber optic glass underneath the jacket performs best when running straight. 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. Use cable managers in all new cabling applications. Fibers and buffer tubes do not have sufficient strength to resist breakage due to normal handling of copper cables. If insertion loss suddenly increases with an adapter or connector, the cause may be dirt. The minimum crew should have one person monitoring the pulling equipment, one monitoring the supply reel, and one coordinating all involved in the installation. In medium fiber-count cables (6 to 24 fibers), the connectors must be staggered when installed to reduce the diameter of the pulling grip. The furcation point is designed for this, as it has a metal sleeve to protect the fiber. Riser cables are generally required for vertical applications and plenum cables are required where there is a positive air pressure space. The minimum air pressure in the duct should be 100 psi with 125 psi recommended. Maintain proper clearance between the fiber optic cable and power cable at all times. Identify cable locations with surface markers. Do not store cable within the closure or pedestal unless there is enough room to accommodate the minimum specified cable bend radius. During cable placement, it is really crucial that the cable not be bent to a smaller radius. Also, avoid excessive twisting or stress on pre-terminated cables during installation. For cables using aramid yarn alone as the strength member, the jacket can be removed to expose the yarn. 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. Careful cable placement facilitates access to transceivers and ports both in active equipment and patch panels. TIA-606-C documents the official standards for cable colors. Cable blowing. Use the location layout to match any specific pre-engineered staggers to the applicable equipment into which they are being plugged. For screw-in connectors such as FC connector, tighten them only “finger tight”. If you don’t already know someone here, we’re glad you found us and happy to get to know you! The plan should include equipment and supplies, fiber cable specification, location of equipment, testing requirements, data forms for testing, personnel experience level and assignment, installation methods, identification of potential problem areas, safety issues, etc. Do not rotate the connector when making the connection. Always roll the cable off the spool instead of spinning it off the spool end. All vertical cable must be secured at the top of the run. Do not eat, drink, or smoke in any area in which bare glass fiber is created. Loose tube cables can be more forgiving of abuse than tight buffer cables. 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. Using zip ties on the fiber optic jacket directly can break the fibers. On runs over 100m, use proper lubricants and pull from the middle out to both ends. 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! Mark cable as “Fiber Optic Cable”. Follow Building Codes: Always obey all local, and national, fire and building codes. Silicon Valley's fiber optic products distributor. Copper trunking is thicker and stiffer than fiber optic trunking. Confine fibers and buffer tubes in protective structures, such as splice trays and cable end boxes. It must also be strong enough to meet the NESC requirements and support the loads given in Table A without exceeding 60 percent of … Leave cable and fiber service loops everywhere. A fiber optic cable should be tested three separate times during an installation: on the reel, the splicing test, and the final acceptance test. Without this sectionalization, additional cable pulls can entangle an operating cable and could cause an interruption in service. 50/125 μm FX2000 jumpers for a 50/125 μm FX2000 optical fiber system) and shall be one to five meters long. Implementation of these outlined fiber optic cabling installation best practices will ensure the best environment for proper functioning of your cables. It could also be located in the basement or in the garage. For fiber optic cable, use horizontal finger style with front cover cable managers in a 1U or 2U footprint. Cable Blowing or Jetting in Duct Applications. Identify lightwave equipment that will be used and ensure that the equipment will function properly with the fiber cable being installed. Anticipate obstructions. There is also a chance that some human hands have touched it, or a particulate has scratched it. Get the cable from the local box to your house. Intermediate cable attachment points however are recommended for optimum performance. Look for signs of stress on the cable jacket. Ensure that the proper cable length has been installed before cutting off excess cable. 2. In general, fiber optic cable can be installed with many of the same techniques used with conventional copper cables. 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. Keep in mind that “pinching” the fiber optic cable also damages the glass, thereby ruining performance. www.cablexpress.com. Failure to follow the same can lead to fatal consequences to them as well as people in the vicinity. 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. After the cable has been installed, and the pulling tension removed, the cable may be bent to a radius no smaller … Methods of duct installation, installation preparation and … 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. 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. Duct Installation of Fiber Optic Cable 1. Future plans for change will be discussed, as well as the bandwidth required. The layout should include the destinations of the fiber trunk assemblies, referred to as “Trunking Locations.”. Cable blowing. But be consistent. To minimize cable tensions, reel vault locations should be set near the sharpest bend locations. Cables that are installed in the vicinity of high-voltage power lines should be grounded, including all-dielectric cables. Cap off or seal the ends of cables with water blocking gel or grease. This can be accomplished by weaving the strength member into the fingers of the grip, and then taping it together. Service loops allow you to pull excess cable or fiber into a location where you have experienced a problem.
