Testing the parameters of optical modules

In using the use of optical modules, it is unavoidable to encounter a variety of problems. In order to reduce the problematic failure phenomenon, but also to protect the stability of the optical module through. There will exist different detection functions for optical modules.

1X9 module is mainly through the signal loss detection function, this communication process signal detection, when the optical power is too large or too small, resulting in the inability to receive the signal, will make the 1X9 module SD pin pull to ground, so that the optical transceiver communication lights out, so as to show the loss of signal.

The SFP module is mainly to check whether the DDM, wavelength, distance and other parameters are normal, if they are not, replace the peripheral equipment or by replacing the optical interface with a matching optical module.

DDM information – check whether the parameters are normal by using the command “show interfaces transceiver detail”, if an alarm appears, it means that the optical module is faulty or the optical module does not match the optical interface type. If an alarm appears, 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 the two ends of the optical module wavelength, distance, etc., whether the same, if there is an error, this to replace the optical module for the use of pairs.

The above is article brought to you by Shenzhen HDV photoelectric Technology Co., Ltd. To check the optical module parameters knowledge. The module products produced by the company cover optical fiber modules, Ethernet modules, optical fiber transceiver modules, optical fiber access modules, SSFP optical modules, and SFP optical fibers, etc.
