3.11.2 Detecting the Actual Input Power of the Two-Fiber
Bidirectional Optical Port
This topic describes how to detect the actual input optical power of a two-fiber bidirectional
optical port to ensure that the actual input optical power of the optical port is in the normal range.
Prerequisites
A calibrated optical attenuator, an optical power meter, the patch cords with different splices,
and an optical connector must be available.
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 detecion.
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 front panel of 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 the device properly as shown in Figure 3-40.
