Precautions
DANGER
Do not look into the Tx laser port and the fiber connector on the optical interface board without
eye protection.
l Use the unit dBm of the optical power meter for the detection.
l Use the single-mode optical fiber for the single-mode optical module and the multi-mode
optical fiber for the multi-mode optical module.
l The fiber interface and the optical connector on the optical interface board must be clean
and connected properly.
l The length of the patch cord used for the detection is 2-5 m generally. It is recommended
that you use the new patch cord.
Procedure
Step 1 Connect one end of the patch cord of the optical power meter to the Tx connector of the detected
port, and the other end to the optical power meter, as shown in Figure 3-39.

Step 2 Set the detecting wavelength of the optical power meter based on the working wavelength of
the detected port.
Step 3 Use the optical power meter for the detection. After the value displayed on the optical power
meter stops changing rapidly and turns stable gradually, record the optical power value.
