ABSTRACT:
An optical fiber cable (20) which is suitable for service from a distribution closure to a customer's premises includes a transmission media core (21) enclosed in a relatively rigid tubular member (40). The relatively rigid tubular member is enclosed in a jacket (44) comprising a plastic material which has a cut-through resistance which is substantially less than that of the tubular member. Interposed between the tubular member and an outer surface of the jacket is a strength member system comprising two yarn-like longitudinally extending strength member groups (52--52). The strength member grops are diametrically opposed to each other and are disposed in engagement with the tubular member.
