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.

Abstract: A transition device (10) is provided to facilitate the forming of a lightguide ribbon cable unit (22) from a plurality of individual insulated light conductors (24). The light conductors (24), which each include a light-conductive glass fiber (12) surrounded by an inner layer (14) of insulation and an outer layer (16) of insulation, are mounted into converging channels (44) of the transition device (10), such that portions of the glass fibers which have been stripped of insulation extend from an exit end (50) of the device arranged in a parallel side-by-side array between two strips of pressure-sensitive adhesive tapes (18 and 20) to form the ribbon cable unit (22). The assembled transition device (10), ribbon cable unit (22) and light conductors (24) produce an optical fiber assembly (93).
