The optical fibers of the USG are classified into three categories, LC/PC-LC/PC,
LC/PC-SC/PC, and LC/PC-FC/PC, based on the types of connectors on both ends, as shown
in Table

Issue 03 (2015-01-26)
The procedure and precautions for inserting and removing SC/PC connectors are as
follows:
− Insert and remove the connector along the axis without rotating the connector.
− When you insert the fiber, carefully insert the fiber head to the optical interface on the
interface board.
− To remove the optical fiber, slightly push the fiber connector, and pull out the
connector.
FC/PC connector
The procedure and precautions for inserting and removing FC/PC connectors are 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 in clockwise
direction, 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 is loose. Then slightly pull out the optical fiber.

Transmission
Mode
Single-mode/Multi
-mode
Use single-mode and multi-mode optical fibers as required.
Tx (sending) of the local device corresponds to Rx (receiving) of the peer device.
The wavelengths of the optical modules on both ends must be the same.
Do not overbend optical fibers, and the bend radius must not be shorter than 40 mm.
