Abstract
A ferrule block comprises a ferrule block body which is attached to an optical device module, which houses in its package an optical device for sending or receiving a light signal, to optically couple to an optical fiber communicating between the optical device module and an external optical communication system and a shell made of an insulating material which is provided at the tip of the ferrule block body, wherein a flange which hits against the tip of the ferrule block body is provided on the outer periphery of the shell.
Claims24
A ferrule block, comprising:
- a ferrule block body which is attachable to an optical device module, wherein the ferrule block body houses a ferrule and an optical device for sending or receiving a light signal and for optically coupling to an optical fiber communicating between the optical device module and an external optical communication system;
- a sleeve for accommodating the ferrule;
- and
- a shell made of an insulating material which is provided at a tip of the ferrule block body and covers an outer periphery of the sleeve,
- wherein the shell comprises an outer periphery, two ends, and a flange disposed along the outer periphery of the shell such that the outer periphery of the shell extends from the flange in two directions towards the two ends, wherein the flange hits against the tip of the ferrule block body and the flange is configured to abut an outer frame of an optical connector.
