An optional Gigabit SFP (1000BASE-SX, 1000BASE-LX, 1000BASE-LH, or
100BASE-FX) transceiver can be used for a backbone connection between
switches, or for connecting to a high-speed server.
Each single-mode fiber port requires 9/125 micron single-mode fiber optic
cable with an LC connector at both ends. Each multimode fiber optic port
requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an
LC connector at both ends.

ARNING
:
These switches use lasers to transmit signals over fiber optic
cable. The lasers are compliant with the requirements of a Class 1 Laser
Product and are inherently eye safe in normal operation. However, you
should never look directly at a transmit port when it is powered on.

ARNING
:
When selecting a fiber SFP device, considering safety, please
make sure that it can function at a temperature that is not less than the
recommended maximum operational temperature of the product. You must
also use an approved Laser Class 1 SFP transceiver.
1.
Remove and keep the Fiber port’s rubber plug. When not connected to
a fiber cable, the rubber plug should be replaced to protect the optics.
2.
Check that the fiber terminators are clean. You can clean the cable
plugs by wiping them gently with a clean tissue or cotton ball
moistened with a little ethanol. Dirty fiber terminators on fiber optic
cables will impair the quality of the light transmitted through the cable
and lead to degraded performance on the port.
3.
Connect one end of the cable to the SFP port on the switch and the
other end to the SFP port on the other device. Since SFP connectors are
keyed, the cable can be attached in only one orientation.
