Do not look into the optical interface of the optical module or the optical fiber connector
without eye protection.
Before connecting optical fiber cables, read the following precautions:

Procedure
Step 1 Insert an optical transceiver into the SFP or SFP+ port of the USG.
Step 2 Remove the dust cap from the optical transceiver.
Step 3 Before connecting an optical fiber, attach temporary labels to both ends of the optical fiber for
identification.
Step 4 Remove protective caps from optical fiber connectors, insert optical fibers into the optical
transceiver, and connect the fiber to the peer device.
Ensure that the TX and RX ports on one end of the optical fiber cable are connected to the RX
and TX ports (respectively) on the other end.
Issue 03 (2015-01-26)
Do not overbend optical fibers, and the radius should not be shorter than 40 mm.
Do not bundle the optical fibers too tight. Otherwise, the transmission performance of
the optical fibers and the communication between devices might be adversely affected.
The optical module has been installed.
Set aside the dust cap properly for future use. After optical fiber are disconnected for maintenance, use
the dust cap to prevent the optical transceiver from dust.
Ensure that the Tx and Rx ports are correctly connected.
