Questions about HTF optical modules
Q: Does our module have the data diagnostic monitoring interface (DDMI) specified by the SFF-8472 standard?
Melanie from HTF：
The SSFF-8472 standard is a key factor in judging whether the quality and compatibility of compatible optical modules pass the test. It is formulated by the SFF committee to define the data diagnostic monitoring interface (DDMI) of the optical module, which can help us understand the optical module parameters in real time.
DDMI is also called DDM or DOM. When one or more items of data during the operation of the optical module exceed the standard parameters specified by the manufacturer, it has an alarm function.
Q: Does our module have a fault location function?
The fault location function can help engineers find problems and fix them quickly
Optical module and reduce down time.
If the compatible optical module has a data diagnostic monitoring function (DDM), we can use DDM to analyze each parameter of the optical module, such as output optical power, virtual channel connection (VCC), etc., to determine the failure point in the optical fiber link.
