2.3.3 SFP Transceiver Installation
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 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.
Caution:
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.
Note:
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.
Figure 2-3 Making Connections to SFP Transceivers
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.
3. Connect one end of the cable to the LC port on the switch and the other end to the LC port on the
other device. Since LC connectors are keyed, the cable can be attached in only one orientation.
4. As a connection is made, check the Link LED on the switch corresponding to the port to be sure that
the connection is valid.
The 1000BASE-SX, 1000BASE-LX and 1000BASE-LH fiber optic ports operate at 1 Gbps full
duplex.
