Abstract
Optical transceivers include receiver-side and transmitter-side optical switches that selectively route optical signals to be transmitted to a wavelength division multiplexer or demultiplexed received signals to corresponding photodetectors. Other optical signals are transmitted or received via optical fibers and directed by the optical switches without wavelength multiplexing. In some examples, the switches are programmable and data routing can be altered as desired. In other examples, the switches are fixed, and data routing is altered by switch replacement.
