SC Fiber Connections
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.
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.
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.
