Connecting Fiber-Optic Cables to MT-RJ Ports

This section provides the procedures for connecting a multimode fiber-optic segment from the
network or other devices to
•
an MT-RJ port connector of a Mini-GBIC (MGBIC-MT01, MGBIC-LC01, or MGBIC-LC09)
in a 1G-2MGBIC, or
•
a fixed MT-RJ connector of an optional 1H-8FX.
Each fiber-optic link consists of two fiber-optic strands within the cable:
•
Transmit (TX)
•
Receive (RX)
The transmit strand from a device port connects to the receive port of a fiber-optic Fast Ethernet
device at the other end of the segment. The receive strand of the applicable MT-RJ port connects to
the transmit port of the fiber-optic Fast Ethernet device.
Enterasys Networks recommends labeling fiber-optic cables to indicate receive and transmit ends.
Many cables are pre-labeled, providing matching labels or tapes at both ends of each strand of
cable.
To connect an MT-RJ cable to a fixed MT-RJ connector of an optional 1H-8FX or Mini-GBIC,
refer to Figure 3-20
1. Remove the protective covers (not shown) from the front panel MT-RJ fiber-optic port
from the connectors on each end of the cable.
.
NOTE: Leave the protective covers in place when the connectors are not in use to
prevent contamination.
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 cable ends
causes problems in data transmissions. If the ends of the fiber-optic strands become
contaminated, use a canned duster to blow the surfaces clean. A fiber port cleaning
swab saturated with optical-grade isopropyl alcohol may also be used to clean the ends.
