Optical fiber Ethernet switch and control method

Abstract

The invention discloses an optical fiber Ethernet switch and a control method. The optical fiber Ethernet switch comprises a microcontroller, a first switch tube, a second switch tube and an optical module, wherein the receiving power supply input end of the optical module is connected with a power supply through the first switch tube; the sending power supply input end of the optical module is connected with the power supply through the second switch tube; the control end of the first switch tube is connected with a first control signal output end of the microcontroller; the control end of the second switch tube is connected with a second control signal output end of the microcontroller; and a control signal input end of the microcontroller is connected with an optical signal detection pin of the optical module. When the microcontroller detects that the optical signal detection pin of the optical module has an optical signal, the receiving and sending power supplies of the optical module are started through the switch tubes, and the optical module works normally; and when the microcontroller detects that the optical signal of the optical signal detection pin of the optical module disappears, the receiving and sending power supplies of the optical module are turned off through the switch tubes, the optical module enters a sleep mode automatically, and the power consumption of the Ethernet switch is reduced greatly.

Description

[technical field] [0001] The invention relates to an Ethernet switch, in particular to an optical fiber Ethernet switch and a control method. [Background technique] [0002] The Ethernet switch is a switch based on Ethernet to transmit data, and Ethernet adopts a local area network in which a shared bus is used to transmit media. The structure of the Ethernet switch is that each port is directly connected to the host, and generally works in full-duplex mode. The switch can connect many pairs of ports at the same time, so that each pair of hosts that communicate with each other can transmit data without conflict as if they monopolize the communication medium. [0003] At present, optical fiber Ethernet switches are widely used in the fields of electric power, coal, transportation, and commercial communication. Optical fiber transmission is an indispensable communication method in long-distance communication. Traditional optical fiber Ethernet switches are working normally n...
