Cabletron Systems E2210 Installation Manual page 35

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 the fiber is labeled 1, and the other fiber is labeled 2.
This pattern is repeated at the other end of the cable.
ST type fiber optic connectors attach to ST ports in the same way
that BNC connectors attach to BNC ports. You slide the connector
into the port with the alignment key on the connector inserted into
the alignment slot on the port. Then turn the connector until it is
locked in place (see Figure 3-3, below).

Do not touch the ends of the fiber optic strands and do not let
the ends come in contact with dust, dirt, or other
NOTE
contaminants. Contamination of the ends can cause data
transmission problems. If the ends become contaminated,
clean them with denatured alcohol using a soft, clean, lint
free cloth. If this does not work, use a fiber optic polishing kit
to polish the end of the strand.
