VF-45 Fiber Connections
Each device requires a 62.5/125 micron or 50/125 micron
multimode fiber optic cable with VF-45 connectors at both ends.
1. Remove and keep the VF-45 port’s plastic 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 using an appropriate VF-45 cleaning kit. Dirty fiber
terminators on fiber optic cables will impair the qu ality of the
light transmitted through the cable and lead to degraded
performance on the port.
3. Connect one end of the cable to the VF-45 port on the switch
and the other end to the VF-45 port on the other device. Since
VF-45 connectors are keyed, the cable can be attached in only
one orientation.
4. As each connection is made, check the Link LED on the
switch’s front panel for the corresponding port to be sure that
the connection is valid.
You can run a fiber link up to 2 km (1.24 mi.) in full-duplex mode,
and 412 m (1351 ft.) in half-duplex mode. However, note that
power budget and timing constraints must also be considered
when calculating the maximum cable length for your specific
environment.
