How to check the quality of compatible optical transceiver modules?

Date:2018-08-03 15:20 From:C-LIGHT Onclick:

Some people worry that third-party optical  transceiver modules can't be compatible with their own devices. Others think that third-party optical transceivers can run well, and they are compatible and cost-effective. They are the best choice to replace expensive original optical  transceivers.

 

Third-party optical  transceivers are increasingly popular in the optical communications market because there are many vendors that offer third-party optical transceivers that are affordable, good quality, and compatible.How to check the quality of compatible optical transceiver modules is an important key.C-light brings you knowledge about it and hopes to help you.
 

How to check the quality of compatible optical transceiver modules?
 

1.  DDMI and fault location function

The SSFF-8472 standard was developed by the SFF committee to determine the key factors for the quality and compatibility of compatible optical transceiver modules. Referred to as the data diagnostic monitoring interface (DDMI/DDM/DOM). It has an alarm function when one or more data in the operation of the optical transceiver module exceeds the standard parameter. Fault location function helps engineers find problems and quickly fix optical transceiver modules and reduce downtime.
 

Parameter Range Stand error
Voltage 0~6.55 V +/-3% Standard value
Temperature -128~128 ℃ +/-3 ℃
Receive sensitivity -40~8.2dBm +/-3dBm
Output optical power -40~8.2dBm +/-3dBm
Bias current 0~131mA +/-10% Standard value
DDMI monitoring parameters
 

2.  Pass the compatibility verification

Compatibility needs to be tested on the switch to check the operation of the module. This is the only way to determine the performance of the optical transceivers. Generally, the higher the performance of the optical transceivers, the stronger the compatibility.
 

Shenzhen C-Light Network Communication Co., Ltd is a manufacturer integrating R&D, production and sales,committed to optical transceiver modules, passive optical products, data exchange equipment. The optical transceivers modules provided are compatible with switches of major brand network devices, such as Cisco, Juniper, Huawei, HP, and Huawei.
