Installation of optical fiber cable trays
Cable trays or raceways often provide a convenient, safe and efficient method of fiber optic cable installation. Trays can be installed in ceilings, below floors and in riser shafts. It covers the most common components used in a fiber tray installation, but each installation is different and the unique circumstances and requirements of any given installation environme qualified technicians. While there are several specific types of listings for power cables, specifically for tray. There are 5 undrilled U-shaped Fiber Cable Input Holes reserved for flexible fiber installation. To use these holes for fiber installation, first use a mini hand drill to drill U-shaped holes as pre-outlined in the Cable Tray Base. Unlike solid-bottom trays that provide continuous support, the open mesh design creates sharp edges, inconsistent support points, and. Recommendations for Fiber Optic Cable Installation Where reels are supplied with protective material fitted over the cable, the protection should remain in place until the cable will be installed. The cable should be bent as little as possible. -
