Fiber Optic SFP Devices
An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX, or
1000BASE-ZX) 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.
Warning: This switch uses 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.
1. Remove and keep the LC 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.
