Check whether an alarm is generated for high transmit power on the peer optical module. To check alarm information, diagnostic information, and manufacturing information about an optical module, run the display transceiver. The QDD Optical Line System (OLS) is a new pluggable optical amplifier that interconnects two routers or switches for transmitting traffic on a limited number of coherent optical channels over a single span point-to-point link. With the QDD OLS pluggable, it's now possible to obtain the. oltage and the bias current. If one of the five parameters is abnormal, ONU registration will be abnormal or packet nt are all for the PON port.
