At the CO, a fiber distribution frame (FDF) integrates a number of OLTs together with splicing trays and connectors, which, in turn, connect the OLTs to the fiber network. COs may contain optical networks. The type of connectors at the OLTs is most often ultra polished connectors with a typical ORL value from 50-55 dB. More modern networks utilize angle polished connectors (APC) with an ORL value of 67-70 dB.
Chapter 3: Deploying and Troubleshooting Fiber Networks Because customers may be located far apart along the feeder, splice enclosures may be located in aerial or underground environments. In this scenario, one cable may be divided into a number of fibers going to different directions. Some typical feeder cable distances can extend up to 30,000 ft. (10 km).
