HUAWEI USG9500 Series
Hardware Guide
l To ensure the normal transmission of optical signals, do not use single-mode optical fibers
l To connect extension optical fibers, purchase LC/PC-LC/PC adapters.
Optical fibers have multiple types of connectors. Common connectors types include LC/PC,
SC/PC, and FC/PC.

There are three types of optical fibers for the USG9500: LC/PC-LC/PC, LC/PC-SC/PC, and
LC/PC-FC/PC, which are based on the types of connectors on both ends of the fibers, as listed
in Table

to connect multi-mode optical modules, nor multi-mode optical fibers to connect single-
mode optical modules.
LC/PC connector
The procedure for inserting and removing LC/PC connectors is as follows:
– Insert and remove the connector along the axis without rotating the connector.
– When you insert the fiber, carefully insert the fiber head into the optical interface on
the interface board.
– To remove the optical fiber, squeeze the pinch on the fiber connector, gently push
on the fiber connector, and then pull it out.
SC/PC connector
The procedure for inserting and removing SC/PC connectors is as follows:
– Insert and remove the connector along the axis without rotating the connector.
– When you insert the fiber, carefully insert the fiber head into the optical interface on
the interface board.
– To remove the optical fiber, gently push on the fiber connector, and then pull out the
connector.
FC/PC connector
The procedure for inserting and removing FC/PC connectors is as follows:
– When you insert an optical fiber, aim the FC/PC connector at the optical interface
on the interface board to avoid damaging the inner layer of the optical interface.
Then insert the fiber into the optical interface, rotate the outer screw jacket
clockwise, and then fasten the optical connector.
– To remove an optical fiber, rotate the outer screw jacket counter-clockwise on the
optical interface until the screw loosens. Then gently pull out the optical fiber.
