the ST connector into the port with the alignment slot on the connector
inserted over the locking key on the port. Turn the connector

3. Attach the other fiber of the pair to the applicable transmit port on the
module. Use the same procedure for insertion of the ST connector.
4. At the other end of the fiber optic cable, attach the fiber pair to the
transmit and receive ports of the device.
If link indicators are present for the fiber optic connection, check that they
are ON. If an indicator is present but not ON, that port does not have a
valid link. Perform each of the following steps until you reach a resolution
of the problem and achieve a link.
•
Check that the device at the other end of the link is ON.
•
Verify proper cross-over of the fiber strands. Try swapping the transmit
and receive connections at only one end of the link.

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 cable ends causes problems in data
transmissions. If necessary, clean contaminated cable ends
using alcohol and a soft, clean, lint-free cloth.
