ABSTRACT:
A terminus for an optical fiber cable (10) has a ferrule (22) with an endwall portion (24) including an axial opening (26) for receiving a glass fiber core. A ferrule central portion (28) is larger in cross-section than endwall portion (24) and the opposite end portion (32) is still larger. In assembly, the fiber jacket (16) or strain relief is peeled back over an underlying sleeve (34) and crimped within the opposite end portion (32). The central ferrule portion (28) has an internal sleeve (40) fitted over a section of the optical fiber with buffer tubing (14) and the ferrule is crimped in place. The fiber outer end portion consists of just the bare glass core (12) received within endwall opening (26).
