Problems solved by technology

Although this solution can detect link failures caused by ONT abnormal light emission, due to the unfixed allocation of EPON ONT uplink time slot lengths, there is no way to detect time slot occupancy problems caused by ONT optical device aging, and it is also impossible to accurately detect each ONT Uplink optical link status

Abstract

The invention provides a system and a method for detecting ONT abnormal luminescence with an OLT in a PON system. The system comprises a CPU module, a PON time slot control module, an OLT light receiving and transmitting module and an optical signal timing module; the OLT light receiving and transmitting module is connected with the PON time slot control module, and the PON time slot control module is connected with the optical signal timing module and the CPU module, and the optical signal timing module is connected with the CPU module. The system and the method for detecting ONT abnormal luminescence with the OLT in the PON system of the invention can be used for accurately detecting state of each ONT uplink data, detecting performance deterioration condition of single ONT, fast locating degradation fault point so as to be convenient for removing hidden danger before further deterioration.

Description

technical field [0001] The present invention relates to the technical field of optical network communication, in particular to an optical line terminal (Optical Line Terminal, OLT) detection of an optical network terminal (Optical network terminal, ONT) abnormality in a passive optical network (Passive Optical Network, PON) system Light emitting systems and methods. Background technique [0002] At present, the PON optical network has been widely used in the access network. Its network topology is that one OLT port is connected to multiple ONT devices, and the downlink data is broadcast by the OLT to all ONTs. Multiple ONT devices send uplink data on the same wavelength through time-division multiplexing, and the allocation of uplink time slots is determined by the OLT. Therefore, the network topology of the PON is a point-to-multipoint master-slave communication mechanism, and the OLT precisely controls the start time and end time of sending uplink data of each ONT device....
