Compact, tunable, submersible dry mate n-pin optical connector

摘要

A multi-pin connector with a small envelop and low insertion loss capable of operating while submerged is described within. This configuration avoids the tolerance stack up troubles that has plagued other similar designs thereby allowing it to achieve a low insertion loss without the typical cost drivers of tighter tolerances. In addition this invention incorporates as relatively simple method of tuning each pair of connectors thereby further reducing the insertion loss for each matched pair.

主权项

1. An multi-channel optical connector capable of operating while submerged in a fluid comprising:
a plurality of optical fibers; a pair of end caps with an environmental seal around said optical fibers; a male housing and a female housing; a lock nut securing said male housing to said female housing; a plurality of environmental seals between said males housings and said female housing; a plurality of floating split sleeves; a plurality of alignment pins; a pair of ferrule bundle assemblies each consisting: a front plate; a back plate; a ferrule assembly holder; wherein one ferrule bundle assembly is secured in said male housing and the other ferrule bundle assembly is secured in said female assembly; and a plurality of ferrule assemblies secured in said ferrule bundle assemblies; said ferrule assembly further consisting: a ferrule holder; a ferrule being secured in said ferrule holder; a spring around the body of said ferrule holder; and said optical fiber being secured within said ferrule.
