Patent ID: 8600235

Claim:
A device comprising: a splitter to: receive a signal at a first wavelength; split the received signal into a first portion and a second portion; and transmit the first portion and the second portion; a receiver to: receive, by a detector of the receiver, the first portion from the splitter; convert, by the detector, the first portion from a first format to a second format; transmit, by the detector and to a recovery unit of the receiver, the converted first portion; recover, by the recovery unit, a clock signal from the converted first portion; receive, by a deframer of the receiver, the converted first portion and the clock signal; and forward, by the deframer, the converted first portion to a processor; and a transmitter to: receive, by a framer of the transmitter, the converted first portion from the processor; transmit, by the framer and to a modulator of the transmitter, the converted first portion; receive, by the modulator, the second portion from the splitter; modulate, by the modulator, the second portion, based on receiving the converted first portion, to create a modulated signal; and transmit, by the modulator, the modulated signal at the first wavelength.
