Abstract
Systems and methods for repeating optical signals. A scalable transceiver based repeater includes one or more transceivers. Each transceiver includes an optical receiver that receives a channel of an optical signal. The optical transmitter in each transceiver transmits the channel received by the associated optical receiver. A switch is used to redirect the channels, which may be in an electrical form at the switch, from the optical receivers back to the optical transmitters. The switch can also be used to add/drop the channels from the repeater. The optical transmitter and/or the optical receiver of each transceiver may also include a clock/data recovery circuit (CDR). The repeater is scalable because transceivers can be added/replaced as needed. A demultiplexor can separate an optical signal into the channels that are received by the optical receivers. A multiplexor combines the channels generated by the optical transmitters.
