An optical cable assembly includes an optical cable having an end that extends a length. The optical cable includes a plastic optical fiber (POF) and a buffer surrounding the POF along a portion of the length of the end of the optical cable. A terminus assembly terminates the end of the optical cable. The terminus assembly includes a terminus body having a cable passage and a crimp zone. At least a portion of the length of the end of the optical cable extends within the cable passage of the terminus body such that the terminus body surrounds the buffer of the optical cable at the crimp zone. The terminus body is mechanically crimped over, in engagement with, the buffer of the optical cable at the crimp zone.
