Select a high-quality fiber connector. If a non-standard fiber

connector without chamfering is used, internal ceramic sleeves
such as the optical module, flange, or optical splitter could be
damaged.
Ensure that the fiber connector is in good condition, the latch is not

disrupted and keeps elasticity, and the connection to the peer end
is normal.
Before connecting an optical fiber, check that there is no obvious

surface defect such as stain, scratch, dent, or pit. If the fiber
connector, flange, or optical module is dirty, clean it with alcohol
and clean cotton (or a clean cotton rod).
When using an optical fiber to connect the camera, if a flange is

required for connecting the fiber connector, determine the model
of the flange according to the type of the fiber connector on the
peer device first, or perform cascading by directly using an optical
splitter.
When using a fiber connector to interconnect with a flange, aim

the fiber connector at the slot of the flange so as to ensure proper
interconnection.
