Connecting a Fiber Optic Segment to the
FE-100FX and FE-100F3
The FE-100FX and FE-100F3 have SC style network ports. See 
. Cabletron Systems offers fiber optic cables that use SC style 
connectors. The SC connectors are keyed to ensure proper crossover of 
the transmit and receive fibers.
Fiber Optic Network Connection
1.
Remove the protective rubber covers from the fiber optic ports on the 
applicable port on the module and from the ends of the connectors. 
Leave the covers on unused ports.
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.
Ensure that, when connecting an FE-100F3, single mode cable 
is used and the device at the other end of the cable is 
compatible for use with single mode fiber.
!
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. When 
viewing the output optical port, power must be removed from 
the network adapter.
