Abstract

Optical fiber ferrules (10, 20) for making optical or optical and electrical connections are disclosed, along with receptacle and plug fiber optic interface devices (60, 70) using the ferrules, and cable assemblies (6, 7) using the fiber optic interface devices. The optical fiber ferrules support optical pathways (14) and have front ends (12F, 22F) with mating geometries that facilitate a relatively high number of mating/unmating cycles. The ferrule is translatable within the enclosure (62e, 72e). Resilient members (75) provide the ferrule with forward-bias and rear-bias positions when the fiber optic interface device is un-mated and mated, respectively.
