Abstract
Abstract A composite fiber cutting and terminating apparatus includes first and second housings supported for relative movement, the first housing supporting therein both a terminating device, such as a photodiode, and a cutting device. The second housing retentively engages an optical fiber. Upon relative movement of the housings, the fiber is initially cut to define a termination end face and the termination end face is thereafter placed in registration with the detention device.
