Fiber pigtail for optical communication module

摘要

The present invention relates to a fiber pigtail for an optical communication module for converting an electrical signal into an optical signal and outputting the optical signal. The fiber pigtail for the optical communication module of the present invention includes a cylindrical member for protecting a laser diode, a photodiode, In the combination of the first ferrule and the second ferrule provided to protect the end portion of the fiber, the second ferrule is coupled to the through hole provided in the central portion of the first ferrule, wherein the through-The outer surface of the second ferrule is formed to have a male thread shape and the overall length of the paralle is adjusted according to the rotation direction of the second ferrule so that the light output from the laser diode can be accurately focused on the fiber.
