check the optical module parameters

In the use of optical modules, it is inevitable to encounter a variety of problems. To reduce the fault phenomenon and ensure the stability of the optical module. There are different detection functions for optical modules.

 

The 1X9 module mainly detects the signal in the communication process through the signal loss detection function. When the optical power is too large or too small, resulting in the failure to receive the signal, the SD pin of the 1X9 module will be pulled to the ground, so that the communication light of the optical transceiver will be turned off, so as to show the signal loss.

 

SFP module mainly checks whether parameters such as DDM, wavelength, and distance are normal. If they are abnormal, replace peripheral devices or replace optical modules that match the optical interface.

 

DDM information: Run the “show interfaces transceiver detail” command to check whether the parameters are normal. If an alarm is generated, it indicates that the optical module is faulty or the optical module does not match the optical interface type.

 

Wavelength/distance – through the “show transceiver interface” command to check whether the wavelength, distance, etc. of the optical modules at both ends are consistent, if there is an error, replace the optical modules used in pairs.

 

The above is an explanation of the inspection optical module parameters brought by Shenzhen HDV Phoelectron Technology LTD. The module products produced by the company cover optical fiber module, Ethernet module, optical transceiver module, optical fiber access module, SSFP optical module, SFP optical fiber module and so on. The above module class products can provide support for different network scenarios. For the above products, it is paired with a professional and strong R & D team to provide technical support for customers, and a thoughtful and professional business team to provide quality service for customers in the early consultation and later work.
