Switch's 8‐Pin Serial Port
Fiber Optic SFP Devices
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.
