Each single-fiber SC connector on the switch’s front panel connects directly to a
CPE at the subscriber’s premises.
The switch’s single-fiber ports require one strand of 9/125 micron single-mode
fiber optic cable with an SC connector at the switch end.
An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX, 1000BASE-
LH, 1000BASE-LHX, 1000BASE-ZX, 1000BASE-BX20, or 1000BASE-BX10) can
be used for uplink connections from the switch to other network devices at the
CO. A Gigabit SFP transceiver may also be used for long distance connections to
devices at another service provider site.
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.
1.
Remove and keep the SC/LC 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.

ARNING
:
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.

ARNING
:
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.
