Abstract:
1. An optical transceiver for communication over an optical link, the optical transceiver comprising: at least a first laser driver circuit configured to receive a first electrical data signal and to produce a first electrical drive signal; at least a first laser diode configured to receive the first electrical drive signal produced by the first laser driver circuit and to produce at least a first optical data signal having a first data rate; at least a first bi-directional optical multiplexer (MUX) configured to receive the first optical data signal and to launch the first optical data signal into a first end of a first multimode (MM) optical fiber with an offset, the first bi-directional MUX including at least a first optical beam splitter, wherein a first portion of the first optical data signal passes through the optical beam splitter and enters the first end of the first MM optical fiber with the offset, and wherein a second portion of the first optical data signal is directed by the first optical beam splitter in a direction away from the first optical beam splitter and away from the first end of the first MM optical fiber; at least a first photodiode configured to receive a first received optical data signal that passes out of the first end of the first MM optical fiber, wherein the first received optical data signal is an optical data signal produced by a laser diode of a second optical transceiver connected to a second end of the first MM optical fiber, wherein at least a portion of the first received optical data signal is directed by first optical beam splitter onto the first photodiode, the first received optical data signal having the first data rate, and wherein the first photodiode is configured to convert said at least a portion of the first received optical data signal into a first received electrical data signal; and at least a first amplifier configured to amplify the first received electrical data signal to produce a first amplified received electrical data signal.
