How to Connect to SFP Fiber Optic Ports
Follow these steps to connect cables to 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 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.
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 port on the switch and the other end to
the SFP port on the other device. Since SFP connectors are keyed, the cable can
be attached in only one orientation.

connection is valid.
