ABSTRACT:
An undercarpet cable (40) includes a plurality of longitudinally extending interlocking segments (42--42). The segments are designed each to have an optical fiber (33) housed therein or when interlocked in an assembly to provide a longitudinally extending cavity for receiving an optical fiber. The assembly of segments is capable of being routed along at least two paths which are normal to each other. Advantageously, longitudinal relative motion between adjacent ones of the segments and between the optical fiber and the segments is allowed. As a result, the cable may be routed in tortuous paths under a carpet to service workstations as desired.
