Short distance optical modules support link lengths of 2km and below, medium distance optical modules support link lengths of 10-20km, and long distance optical modules support link lengths of 40km and above. Some are responsible for connections of a few meters between server racks, while others bear the heavy responsibility of spanning tens of kilometers across a city. This difference is the most fundamental dividing line in the field of optical communication. From the perspective of physical layer. SR LR are shorthand labels used on optical transceivers to indicate a “reach class” — in other words, the link distance the module is designed for under standard conditions. In most Ethernet optics, SR targets short links, while LR targets longer links.

If the fault is caused by incorrect configuration or networking environment, change the configuration or networking environment. Check whether the optical modules are Huawei-certified ones. And as part of the Internet infrastructure, optical transceivers play a vital and irreplaceable role. Before troubleshooting the issue, please look at our. Based on typical issues encountered with optical modules in daily switch applications, this document summarizes basic troubleshooting steps for resolving common faults: 1. Check compatibility between the optical module and switch Most switch brands have specific compatibility requirements. Have you ever encountered a Cisco switch interface that constantly flaps (goes up and down) or suddenly enters an err-disabled state? Before you blame the switch or replace the cable, you need to look at the invisible data: the light levels. This document applies to Catalyst switches that run on Cisco IOS® System Software.
