Optical module having additional lens for different connection

摘要

An optical module (30) includes an optical waveguide (31), a first ferrule and a second ferrule (32, 33) connected with the optical waveguide. The optical waveguide includes 2N optical channels (313). The first and the second ferrules includes N mirrors (34, 36) and N+1 lenses (35, 37). N of the 2N optical channels optically couple the N mirrors (34) of the first ferrule with N of the N+1 lenses (37) of the second ferrule, and the remaining N of the 2N optical channel couple N of the N+1 lenses (35) of the first ferrule with the N mirrors (36) of the second ferrule.

1. An optical module comprising:
an optical waveguide having a first end and a second end opposite to the first end, the optical waveguide comprising 2N optical channels extending between the first end and the second end; a first ferrule connected with the first end of the optical waveguide, the first ferrule comprising N first mirrors arranged in one row, and N+1 first lenses arranged in another row, the first lenses disposed spaced apart from the first mirrors; and a second ferrule connected with the second end of the optical waveguide, the second ferrule comprising N second mirrors arranged in one row, and N+1 second lenses arranged in another row, the second lenses disposed spaced apart from the second mirrors; wherein N of the 2N optical channels optically couple the N first mirrors with N of the N+1 second lenses, with the remaining one of the N+1 second lenses unused, and the remaining N of the 2N optical channels couple N of the N+1 first lenses with the N second mirrors, with the remaining one of the N+1 first lenses unused.
