2.4.2 Connecting Optical Fibers
Connect the optical module on the switch by using an optical fiber whose connector matches
that of the optical module. When you are doing this, connect the RX end of one party to the
TX end of the other party to ensure correct Rx/Tx channel connection.
Warning
Do not stare into the 1000BASE-SX/LX ports as invisible laser radiation from
them may hurt your eyes.
2.4.3 Laser Safety
The optical transceiver modules supported by the RG-S5750 are all Class I laser products.
Therefore, pay attention to the following during your use of this product:
n
Do not stare into the optical module Tx ends or the connected fiber jumpers, as invisible

dust may pollute or damage the laser connectors.
Danger
Never stare into the optical module Tx ends and the connected fiber jumpers
to avoid injuries to your eyes.
