Micro Hybrid LC Duplex Adapter

Abstract

A hybrid optical fiber adapter comprises a first adapter end configured to receive a first optical fiber connector, and a second adapter end configured to receive a second optical fiber connector of a different type from the first optical fiber connector. The hybrid adapter further comprises a spring configured to couple to the second adapter end such that the second optical fiber connector received into the second adapter end is disposed between the spring and the second adapter end, so as to allow floating of the second optical fiber connector. In one embodiment, the first optical fiber connector is an LC connector and the second optical fiber connector is a micro connector. The hybrid adapter may be coupled to a module such that the second adapter end protrudes into the module, requiring less space inside the module compared to conventional hybrid adapters, without sacrificing optical performance.
