OPTICAL FIBER CONNECTOR AND CABLE ASSEMBLY WITH DUAL DIAMETER CRIMP SLEEVE

摘要

Connectorizing an optical fiber cable includes mounting at least part of a connector housing about a ferrule assembly; positioning a crimp sleeve so that a distal section of the crimp sleeve is disposed about a proximal end of the connector housing and a proximal section of the crimp sleeve is disposed about a jacketed portion of the optical fiber cable; applying a first force to the distal section of the crimp sleeve to tighten the distal section of the crimp sleeve against the proximal end of the connector housing; and applying a second force to the proximal section of the crimp sleeve to tighten the proximal section of the crimp sleeve against the jacketed portion of the optical fiber cable. Adhesive may be added to the proximal section of the crimp sleeve through an aperture.

1. An optical connector and cable assembly comprising:
an optical cable including at least a first optical fiber and strength members disposed within a cable jacket; a connector housing including a proximal housing portion and a distal housing portion that couple together, the proximal housing portion defining a proximal end of the connector housing and the distal housing portion defining a distal end of the connector housing; a ferrule assembly disposed in the connector housing, the ferrule assembly including a ferrule and a ferrule spring, the ferrule having a distal end face that is accessible at the distal end of the connector housing, the ferrule holding the first optical fiber of the optical cable, the ferrule spring biasing the ferrule in a distal direction relative to the connector housing; a crimp sleeve having a proximal section and a distal section, the distal section of the crimp sleeve being tightly crimped to the proximal end of the proximal housing portion of the connector housing to retain the strength members thereat, and the proximal section of the crimp sleeve being adhered and loosely crimped to the cable jacket, the proximal section of the crimp sleeve defining an aperture sized to receive an injection of adhesive; and adhesive disposed at the proximal section of the crimp sleeve.
