Remove and reinstall the optical module. If the fault persists, replace the optical module with a normal one of the same type to check whether the optical module is faulty. If the fault persists, collect log
On an optical network, a sender needs to convert electrical signals into optical signals before sending them to a receiver, and the receiver needs to convert received optical signals into electrical signals.
The following uses the Moduletek SFP-10G-LR module connected to a Huawei S6700 switch as an example to introduce how to read information of the connected optical module on a Huawei switch.
Context Optical attenuation may occur during optical signal transmission. As such, the transmission distance affects the quality of signals received by the remote end. You can adjust the signal transmit
This article summarizes several solutions for using optical modules with switches and common problems encountered during usage, along with specific solutions.
An electrical variable optical attenuator (EVOA) module is used to adjust the optical power of signals. Note: As pluggable SFP optical modules, EVOA modules are optional.
If the transmit optical power remains low, replace the optical module or install it in another optical interface to check whether it is faulty. If the original optical module is faulty, replace it with a
Ensure that the transmit and receive power values of the two optical modules are in the normal ranges. Otherwise, traffic forwarding on the optical interfaces may be abnormal or the optical
We found that there would be fault PON modules, so we test each board and each PON module optical power, and record the data on the test report before delivery, to guarantee quality.
The transmit power of a long-distance optical module is often larger than its overload power. Therefore, when using such optical modules, select optical fibers of an appropriate length to ensure that the
