Step 4 Repeat the preceding steps three times, and then check whether the detected value of the optical
power meets technical requirements (determined by the specifications of different optical
modules).
Step 5 If the detected optical power value does not meet the technical requirements (see the following
table for the detailed technical specifications), check whether the detecting wavelength set by
the optical power meter is consistent with the transmit wavelength of the optical module. In
addition, check whether the connection point of the optical port is loose.
Step 6 After the detected optical power value meets the technical requirements, resume the fiber
connection of the detected port.
