How to Connect to SFP/SFP+ Fiber Optic Ports
– 47 –
Connection Procedure Follow these steps to connect cables to SFP/SFP+ transceiver ports.
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.
Warning:
When selecting a fiber SFP/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/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/SFP+ port on the switch and the other
end to the SFP/SFP+ port on the other device. Since SFP/SFP+ 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 to be sure that the
connection is valid.
Note:
Be sure to secure cables properly and route them away from the switch
without exceeding the minimum bending radius for fiber cables (typically a few
inches). Use cable ties to bundle cables together and secure coiled loops of excess
cable. Do not let cables hang free supporting their own weight or pull in any way
that puts stress on the connectors.
