Problems solved by technology

[0002] Due to viruses, network loops, or network card damage, it is easy to cause a broadcast storm on the network, thereby paralyzing the entire network system
Traditionally, many non-network-managed switches and Layer 2 managed switches do not have the function of broadcast storm suppression, which often causes serious losses.

Abstract

The invention provides an SFP optical module. The SFP optical module comprises a golden finger, a programmable logic device, a laser driving chip, an emitting laser and a receiving laser, wherein theprogrammable logic device is connected with the golden finger through a SERDES interface and an IIC interface; the programmable logic device is connected with the laser driving chip through the SERDESinterface and the IIC interface; an output end of the laser driving chip is connected with an input end of the emitting laser, and the input end of the laser driving chip is connected with the outputend of the receiving laser. The invention further provides a method for restraining the broadcast storm of the SFP optical module. The SFP optical module provided by the invention has the advantagesthat the effect of restraining the broadcast storm is realized, and the SFO module is small in volume and low in power consumption.

Description

technical field [0001] The invention relates to an SFP optical module, in particular to an SFP optical module and a method for suppressing a broadcast storm. Background technique [0002] Due to viruses, network loops, or network card damage, etc., it is easy to form a broadcast storm on the network, thereby paralyzing the entire network system. Traditionally, many non-network-managed switches and Layer 2 managed switches do not have the function of broadcast storm suppression, which often causes serious losses. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides an SFP optical module and a method for suppressing broadcast storms. [0004] The present invention provides an SFP optical module, including a golden finger, a programmable logic device, a laser driver chip, a transmitting laser and a receiving laser, wherein the programmable logic device is connected to the golden finger through a SERDES interface and an II...
