What Is the Problem Caused by Low Optical Power of FC switch?

Hello, everyone!

Do you know what is the problem caused by low optical power of FC switch? Don't worry, the post will share with you!

Question

What Are the Problems Caused by Low Optical Power of FC switch?

Answer

Generally, if the transmit power of a multi-mode optical module is lower than 300 uW, the optical power is low. If the transmit power is lower than 300 uW, CRC error codes are generated during transmission and the number of invalid ITW transmission words increases. Replace the optical module.

The following figure shows that the port optical power is lower than 300 uW：

Checked the porterrshow error count of the FC switch. The command output showed that a large number of CRC errors occurred on the corresponding port.

Thanks!
