CONNECTING A FIBER OPTIC LINK SEGMENT

When connecting a ﬁber optic link segment to the EMC39-12, keep the

following in mind:

Each ﬁber optic link consists of two strands of ﬁber optic cabling: the

transmit (TX) and the receive (RX). The transmit strand from a module

port connects to the receive port of a ﬁber optic Ethernet device at the

other end of the segment. The receive strand of the applicable port on the

module connects to the transmit port of the ﬁber optic Ethernet device.

Cabletron Systems recommends labeling ﬁber optic cables to indicate

receive and transmit ends. Many cables are prelabeled, providing

matching labels or tapes at both ends of each strand of cable.

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.

CAUT ION

Contamination of cable ends causes problems in data

transmissions. If necessary, clean contaminated cable ends

using alcohol and a soft, clean, lint-free cloth.

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 one fiber to the applicable receive port on the module. Insert

the ST connector into the port with the alignment slot on the connector

inserted over the locking key on the port. Turn the connector

clockwise to lock it down.
