4.1.2.2 Fiber Connection: SC to ST
Follow the directions in this section if you are connecting a non-Cabletron
Systems device to the FE-100FX using different types of connectors such
as SC to ST.
The physical communication link consists of two strands of fiber optic
cabling: the transmit and the receive. Connect the transmit strand from the
applicable port on the module to the receive port of the fiber optic
Ethernet device at the other end of the segment. Connect the receive
strand of the applicable port on the module to the transmit port of the fiber
optic Ethernet device.
Label the fiber optic cable to indicate which fiber is receive and which is
transmit. Cabletron Systems fiber optic cable is labeled so that one fiber is
labeled 1, and the other fiber is labeled 2 at both ends of the cable. If the
cable was not purchased from Cabletron Systems, label the cable as
described above.
Connect a fiber optic link segment as follows:
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 on
each fiber strand.
2. Attach the fiber labeled 1 to the receive port on the FE-100FX. See
Figure 4-3.
3. Attach the fiber labeled 2 to the transmit port on the FE-100FX.
4. At the other end of the fiber optic cable, attach the fiber labeled 1 to
the transmit port of the device.
!
CAUTION
Do not touch the ends of the fiber optic strands, and do not let
the ends come in contact with dust, dirt, or other contaminants.
Contamination of the ends causes problems in data
transmissions. If the ends become contaminated, clean them
with alcohol using a soft, clean, lint free cloth.
