Abstract: Systems and methods for reconditioning an optical signal by OE (optical-to-electrical) converting the signal, recovering clock and data information and performing 3R reconditioning to reamplify, retime and reshape the converted electrical signal, and EO converting the signal back to the optical domain while the FEC and/or Framing encoding of the optical signal remains intact. An exemplary apparatus may be configured to include a receiver 302 with an optical-to-electrical converter, an electronic distortion estimation and compensation unit 304, an electrical-to-optical converter 308, and a transmitter 310.
