Abstract
An all-optical transmission system includes an optical switch matrix, a plurality of optical components communicating over the optical switch matrix, and a top of rack (ToR) switch coupled to each optical component. Each ToR switch communicates with the optical components and with other ToR switches. The optical component includes a send circuit and a receive circuit with the send circuit having a ToR transceiver to receive data, a multiplexer coupled to the ToR transceiver, a Wavelength Selective Switch (WSS) coupled to the multiplexer, and a circulator coupled to the WSS.
