An optional slide-in 100BASE-FX module may be used for backbone and
long distance connections. A 1000BASE-X module may also be used for a
backbone connection between switches, or for connecting to a high-speed
server.
Each multimode fiber optic port requires 50/125 or 62.5/125 micron
multimode fiber optic cabling with an SC connector at both ends. If you
need to connect to a device with 62.5/125 micron cable that has ST-type
connectors, SMC provides an optional SC-ST Converter (Part Number:
99-012034-091).
Each single-mode fiber port requires 9/125 micron single-mode fiber
optic cable with an SC connector at both ends.
Caution: This switch uses lasers to transmit signals over fiber optic
1. Remove and keep the SC port's rubber cover. When not connected to
a fiber cable, the rubber 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 optic
cables will impair the quality of the light transmitted through the cable
and lead to degraded performance on the port.

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.
