Pigtail cords fall into single-mode (yellow) and multi-mode (orange), and can also be classified into
SC, LC, FC, and so on based on interface type.
Fiber connector
Fiber connectors are indispensable passive components in an optical fiber communication system.
They allow the removable connection between optical channels, which makes the optical system
debugging and maintenance more convenient and the transit dispatching of the system more
flexible.

Precautions
•
Make sure the fiber connector and fiber type match the transceiver module type.
•
The fiber ports on some cards have shielded covers. Remove the shielded covers before using
the fiber ports. Fiber interfaces must be installed with shielded covers when they are not in use.
Keep them safely.
•
Fiber connectors must be protected under safe and reliable outer packing, and be fitted with
dust caps. Fiber connectors must be installed with dust caps when they are not in use. Take
care not to scratch their end face. Replace the dust cap if it is loose or polluted.
•
Before connecting a fiber, use dust free paper and absolute alcohol to clean the end face of the
fiber connector. You can brush the end face only in one direction. You also need to brush the
end face of the fiber port.
