When mounting the tail cable unit, ensure that the optical fiber is not clamped by the device.
Otherwise, the optical fiber could be damaged.
Avoid excessively bending the optical fiber during mounting. If the optical fiber is too long, coil
the optical fiber. Ensure that the coil diameter is greater than 60 mm and the curvature is
greater than 90 degrees.
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 device, 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 at 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.
