OPTICAL NETWORK UNIT COMPLIANCE DETECTION

摘要

An optical line terminal receives a sequence of optical power test transmissions from an optical network unit, wherein the sequence of optical power test transmissions includes a first plurality of consecutive optical transmissions, a second plurality of consecutive optical transmissions, and a third plurality of consecutive optical transmissions. The optical line terminal decides whether the optical network unit is malfunctioning based on an extinction ratio and an average transmit power, wherein the extinction ratio is based on the first plurality of consecutive optical transmissions and the second plurality of consecutive optical transmissions, and the average transmit power is based on the third plurality of consecutive optical transmissions.
