Abstract
Optical engines and optical cable assemblies incorporating optical engines capable of transmitting low-speed and high-speed signals over the same optical fibers are disclosed. In one embodiment, an optical engine includes a low-speed transmit (Tx) line, a low-speed receive (Rx) line, a high-speed data lane, an optical transceiver device, and a control circuit. The high-speed data lane includes a high-speed Tx lane and a high-speed Rx lane. A high-speed signal present on the high-speed Tx lane is converted to a high-speed optical signal at an optical Tx lane, and a high-speed optical signal received at an optical Rx lane is converted to a high-speed signal that is provided to the high-speed Rx lane. The control circuit selectively routes the low-speed Tx signal at the low-speed Tx line directly to the optical transceiver device in real time, and also routes a low-speed Rx signal from the transceiver to the low-speed Rx line.
