Abstract

An optical module includes a laser light supply system and a chip disposed within a housing. The chip includes a laser input optical port and a transmit data optical port and a receive data optical port. The optical module includes a link-fiber interface exposed at an exterior surface of the housing. The link-fiber interface includes a transmit data connector and a receive data connector. The optical module includes a polarization-maintaining optical fiber connected between a laser output optical port of the laser light supply system and the laser input optical port of the chip. The optical module includes a first non-polarization-maintaining optical fiber connected between the transmit data optical port of the chip and the transmit data connector of the link-fiber interface. The optical module includes a second non-polarization-maintaining optical fiber connected between the receive data optical port of the chip and the receive data connector of the link-fiber interface.
