The single-mode optical modules to be installed must match the data rate at the optical
ports.
Do not twist, bend, stretch, or squeeze fiber optic cables during installation.
The cable route depends on actual requirements.
NOTICE
Long-time exposure to the air causes performance exceptions on an optical module.
Therefore, optical modules must be connected to fiber optic cables within 20 minutes
after being unpacked.
