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.

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...
