Abstract

The invention relates to the technical field of optical communications and provides an adaptive OLT optical module and a control method thereof, wherein the optical module includes an analog switch and a self-reset circuit, the control port of an electrical connector is connected with a microprocessor for transmitting a peripheral control signal to the microprocessor, a control 1 signal port and acontrol 2 signal port of the electrical connector are connected with a strobe interface of the analog switch, a strobe control interface of the analog switch receives the signal from the microprocessor and selectively transmits the control 1 signal or the control 2 signal to the microprocessor; the self-reset circuit generates a self-reset signal according to a received burst electrical signal, processes the received burst electrical signal and transmits the signal to a receiver, and the receiver transmits the uplink signal to the electrical connector. The invention adopts an OLT optical module to implement hybrid insertion on a GPON network line card single disk or an EPON network line card single disk, thereby improving networking flexibility and reducing operation and maintenance costs.

Description

【Technical field】 [0001] The invention relates to the technical field of optical communication, in particular to an adaptive OLT optical module and a control method thereof. 【Background technique】 [0002] Passive Optical Network (abbreviated as: PON) network consists of optical line terminal (optical line terminal, abbreviated as: OLT), optical network unit (Optical Network Unit, abbreviated as: ONU) and optical distribution network (Optical Distribution Network , abbreviated as: ODN), because PON network technology has significant advantages such as high performance and low operation and maintenance costs, it has become the mainstream of broadband access in China. Among the existing optical fiber broadband access networks, Ethernet Passive Optical Network (EPON for short) and Gigabit-Capable PON (GPON for short) respectively occupy most of the market share. [0003] The internal structure of the OLT optical module of the GPON network is as follows: figure 1 Shown, inclu...
