CONNECTING A FIBER OPTIC LINK SEGMENT
EMC38-12 USER’S GUIDE Page 3-3
We recommend that you label the fiber optic cable to indicate which
fiber is Receive and which is Transmit. When you buy fiber optic
cable from Cabletron Systems, it is labeled so that: at one end of the
cable, one fiber is labeled 1, and the other fiber is labeled 2. This
pattern is repeated at the other end of the cable. If you did not
purchase your cable from Cabletron Systems, be sure you label your
cable as described above.
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 can cause problems in data
transmissions. If the ends become contaminated, clean them with
alcohol using a soft, clean, lint free cloth.
To connect a fiber optic link segment to the EMC38-12:
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 applicable receive port, labeled RX,
on the module. See Figure 3-2.

3. Attach the fiber labeled 2 to the applicable transmit port labeled TX,
on the module.
4. At the other end of the fiber optic cable, attach the fiber labeled 1 to
the transmit port of the device.
