ABSTRACT:
A communications distribution system (20) provides service for local business and residential premises with fewer splice points required and less waste than encountered in prior art systems. The system includes a feeder distribution interface (60) which is served by a feeder cable or by a carrier system and at least one group interface (61) which is disposed to serve customers' premises. A backbone cable segment (62) extends from the feeder distribution interface to a single group interface and is capable of providing service to a plurality of customer premises. Each customer's premises is served by a single distribution service cable (66) which is connected to a backbone cable segment at a group interface. The single distribution service cables for an area may extend radially or laterally from a group interface.
