CHAPTER 4 | Making Network Connections
10 Gbps Fiber Optic Connections
10 GBPS FIBER OPTIC CONNECTIONS
An optional 10 Gigabit transceiver (SFP+) can be u s ed fo r a backbone
connection between switches.
Single-mode fiber ports require 9/125 micron single- mode fiber optic cable.
Multimode fiber optic ports require 50/125 or 62.5/125 micron multimode fiber
optic cable. Each fiber optic cable mu st have an LC connector attached at both
ends.

ARNING
:
These switches use lasers to tra nsmit 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 operat ion.
However, you should never look directly at a transmit port when it is
powered on.
W
ARNING
:
When selecting a fib er 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 port’s protective cover. When not connected to a fiber
cable, the 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 per fo r ma nc e 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.
