QSFP-DD optical module Read Digital Diagnostic Monitoring(DDM/DOM)

The hardware device in this demonstration is QSFP-DD-200G-SR4

All XFP packaged fiber modules can be used for reference

Prepare multi-mode optical fiber modules and multi-mode loopback modules

After the software opens, log in.

Perform the following steps:

1) Select QSFP-DD Tab

2) Page size set to :8(This value is usually 8, but there are exceptions that vary depending on the IC. If reading fails, consult the module vendor)

    ReadIIC set to  :3(This value is filled in according to the usage, the smaller the value)

3)Check "DDM" in "Read/Write Options"

4) Click "Read" in "Read Options"(If a large number of optical modules are to be read, select Auto and click Read.)

5) Connect the optical fiber module and loopback module to the QSFP-DD port

6) As shown in the figure, the power of the optical module is displayed.(Click "Stop" when finished)

QSFP-DD is a new-generation protocol, and its functions are constantly improving.....
