Abstract: An ultra-short-reach optical transceiver is described. The ultra-short-reach optical transceiver comprises an optical transmitter, an optical receiver, and a clock and data recovery unit. The optical transmitter is configured to transmit a first signal. Additionally, the optical transmitter is nominally designed to transmit data at a designed transmit bit rate of between about 0.9 Gbps and about 1.25 Gbps. The first signal has a bit rate of between about 2 Gbps and about 3 Gbps, and exhibits an eye opening of at least about 50%. The optical receiver is configured to receive a second signal and is nominally designed to receive data at a designed receive bit rate of between about 0.9 Gbps and about 1.25 Gbps. The second signal has a bit rate of between about 2 Gbps and about 3 Gbps. The clock and data recovery unit is coupled to the optical receiver.
