Fiber Optic SFP Devices

An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX or
1000BASE-LH) can be used for a backbone connection between switches,
or for connecting to a high-speed server.
Each multimode fiber optic port requires 50/125 or 62.5/125 micron
multimode fiber optic cabling with an LC connector at both ends.
Each single-mode fiber port requires 9/125 micron single-mode fiber
optic cable with an LC connector at both ends.
Caution: This switch uses lasers to transmit signals over fiber optic
1. Remove and keep the LC port's rubber cover. When not connected to
a fiber cable, the rubber cover 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 cables
will impair the quality of the light transmitted through the cable and
lead to degraded performance on the port.

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.
