Abstract

The invention discloses a control system for achieving multiplexing of a pin of an OLT (optical line terminal) optical module. The control system comprises the OLT optical module and a system main board control unit, wherein the OLT optical module comprises a micro-controller; the system main board control unit and the micro-controller in the OLT optical module are in communication connection, and the multiplexing of an off (TX-Disable) signal of any pin of the OLT optical module and a strength trigger (RSSI-Trigger) signal of received light signal is achieved by changing high and low level states of a state indicating bit in the micro-controller. According to the system, the multiplexing of the off (TX-Disable) signal of any pin of the existing OLT optical module and the strength trigger (RSSI-Trigger) signal of received light signal is flexibly achieved, and flexible use of the optical module is enhanced.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a control system for realizing pin multiplexing of an OLT optical module. Background technique [0002] As a mainstream technology for fixed access, Ethernet passive optical network EPON is mature and stable in performance, and gradually enters a wide range of commercial applications. The SFP optical module is a small hot-swappable optical module that conforms to the MSA protocol. It provides the function of bidirectional data transmission in the optical communication system. It has the characteristics of high transmission rate and small size. The electrical functions of the pins of the existing SFP optical modules are defined and cannot be changed, which limits the flexible use of the existing optical modules. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a co...
