3.6.2 Connecting a Fiber Optic Segment to theFE-100FX and FE-100F3The FE-100FX and FE-100F3 have SC style network ports. See
Figure 3-9. Cabletron Systems offers optional fiber optic cables that use
SC style connectors. The ST connectors are keyed to ensure proper
crossover of the transmit and receive fibers.
Fiber Optic Network Connection
1. Remove the protective plastic covers from the fiber optic ports on the
applicable port on the module and from the ends of the connectors.
NOTES An odd number of crossovers (preferably one) must be
maintained between devices so that the transmit port of one
device is connected to the receive port of the other device and
vice versa.
If the fiber optic cable being used has SC style connectors that
do not resemble MIC style connectors, or has SC connectors
on one end and a different type on the other, such as ST
connectors, ensure that the proper crossing over occurs.
!
CAUTION
The FE-100F3 uses Class 1 lasers. Do not use optical
instruments to view the laser output. The use of optical
instruments to view laser output increases eye hazard. Before
viewing the output optical port, remove power from the network
adapter.
