Optical communication equipment remote hardware reset system

Abstract

The invention discloses a remote hardware reset system of an optical communication system. equipment is connected with optical communication equipment located at a remote side via an optical fiber, each of optical communication equipment located on a local side and the optical communication equipment located on the remote side comprises an optical module, a CPLD / FPGA chip, a series resistor and apower-on reset circuit, wherein the optical module transmits a dark warning signal to the CPLD / FPGA chip, the CPLD / FPGA chip processes the dark warning signal to generate a reset signal, and transmitsthe reset signal to the power-on reset circuit via the series resistor, and after receiving the reset signal, the power-on reset circuit performs hardware reset on the optical communication equipmentlocated on the local side and the optical communication equipment located on the remote side. According to the system provided by the invention, the optical communication equipment can be remotely troubleshot, the troubleshooting time is relative short and the troubleshooting cost is relatively low.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a remote hardware reset system for optical communication equipment. Background technique [0002] No matter the optical communication equipment is access equipment, switching equipment or transmission equipment, there are situations of data blockage or crash. To eliminate this fault, it is necessary to reset the hardware of the optical communication equipment so that the optical communication equipment is in the initial state and start over. run. [0003] At present, most of the hardware reset schemes used in optical communication equipment are power-on single reset, or power-on single reset plus an external reset button. If hardware reset is required, manual on-site operation is required. However, optical communication equipment is often installed in unattended computer rooms, or in remote suburbs and rural areas. Manual troubleshooting is time-consuming and labor-intensive...
