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. Riser cables are generally required for vertical applications and plenum cables are required where there is a positive air pressure space. Use a wet wipe to loosen particles on the end of the cable connector using a circular or straight wiping motion while using care to avoid wiping over area of pad that has already been used. The ducts and innerducts should be kept free of debris and maintained watertight at all times. Patch cords are interconnect cables, which means they should be deployed within racks or cabinets and should not be deployed in ladder racks. 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. If possible, use an automated puller with tension control or at least a breakaway-pulling eye. General Guidelines of the Optical Cable Corporation Installation Guide. Methods of duct installation, installation preparation and … Identification methods typically used are color-coding, labeling/marking, etc. The pulling tape should have a rating for greater than maximum anticipated pulling tension. Test results should be recorded in the memory of a Fluke or comparable test equipment. Do not store cable within the closure or pedestal unless there is enough room to accommodate the minimum specified cable bend radius. 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). The cable weight in an unsupported vertical rise shall be less than the specified long term operating load. Condensation can also form in the bag the fiber is packaged in and find its way under the cap. A split mesh grip is recommended to secure the cable. Use only cable/duct lubricants recommended by its blowing equipment manufacturer for optical fiber cable. Conduit runs should be limited to 100 feet, with no more than two 90-degree bends between pull points or boxes. Lubricate the cable when installing in conduits.
