| 摘要 |
According to embodiments of the present invention, an optical transponder and/or optical transceiver includes a decision circuit, which scales a decision threshold voltage based on power in a received optical signal. In one embodiment, the decision set point may be established based on an expected amplitude or power of an incoming optical signal and the transponder and/or transceiver uses the actual power of the incoming optical signal to adjust the decision threshold voltage.
