Home / The handle of the optical module is too long

Run the display interface transceiver verbose command in the user view to check whether the transmit optical power (Tx Power) of the interface is within the allowed range. If yes, collect alarm, log, and configuration information, and contact technical support personnel. Parts that are held in normal use (prolonged use) are expected to be held for anywhere between 10 seconds to 10 minutes and the temperature is 48°C for all surface types. The case operating temperature of the module is around typically 10 to 15 degrees hotter than the ambient temperature. An optical module is a critical component in modern optical communication systems, directly affecting transmission stability, network reliability, and operational efficiency. Customers in the use of optical modules will more or less encounter a variety of failure problems, such as optical module model selection is correct, the use of jumper is correct and some common problems, customers have the ability to judge and have a clear solution, but for some of the use of.

Checking the Optical Module

If the receive optical power is too high or too low: Change the optical module or fiber of the peer and test the receive optical power again. Check whether the transmission distance and fiber type of the

Check whether the peer optical module matches the local optical module. If they do not match, replace the optical module with one that matches the peer optical module.
