Fiber Optic SFP
An optional Gigabit SFP 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.
WARNING
: This switch uses lasers to transmit signals over fiber optic cable. The lasers
are inherently eye safe in normal operation. However, user should never look directly at a
transmit port when it is powered on.
WARNING
: 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 SFP transceiver.
Step 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.
Step 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.
Step 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. Damage may occur if forced in the wrong orientation.
Step 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.
