Abstract
An Optical Line Termination (OLT) module and an OLT are disclosed. According to an embodiment of the OLT optical module, an optical signal receiver connects with a trans-impedance amplifier of which differential outputs connect with a limiting amplifier. An SD output of the limiting amplifier connects with a clock input of a D trigger and an input of a micro control unit. The D trigger connects with a control signal input of a first switch tube and may cause the first switch tube to be in conducting state when outputting high level. When the optical signal receiver detects an uplink burst signal, the limiting amplifier may generate the SD signal, the D trigger may output high level according to the SD signal and the first switch tube will be in conducting state, so that the micro control unit may detect the received optical power of the uplink burst signal.
