Abstract
Disclosed herein are optical transceivers with multi-laser modules, as well as related optoelectronic assemblies and methods. In some embodiments, an optical transceiver may include: a first laser and a second laser; an optical output path, wherein an output of the first laser is coupled to the optical output path; and switching circuitry to decouple the output of the first laser from the optical output path and to couple an output of the second laser to the optical output path.
Claims24
An optical transceiver, comprising:
- a plurality of lasers including a first laser and a second laser;
- modulator circuitry;
- and
- switching circuitry coupled between the plurality of lasers and the modulator circuitry, wherein the switching circuitry is to selectively couple an output of the first laser to the modulator circuitry or an output of the second laser to the modulator circuitry.
