Connecting Fiber-Optic Cables to Mini-GBICs
This section provides the procedure for connecting 1‐Gigabit Ethernet fiber‐optic segments from
the network or other devices to Mini‐GBIC MT‐RJ or LC port connectors installed in the 2S4082‐25
and 7S4280‐19 NAC Controller PEPs.
Each fiber‐optic link consists of two fiber‐optic strands within the cable: Transmit (TX) and Receive
(RX)
The transmit strand from a module port connects to the receive port of a fiber‐optic Gigabit
Ethernet device at the other end of the segment. The receive strand of the applicable MT‐RJ port on
the module connects to the transmit port of the fiber‐optic Gigabit Ethernet device (shown in
Figure 4‐10 ) or LC cable connector (shown in Figure 4‐11 ).
The following procedure describes how to connect an MT‐RJ cable ( Figure 4‐10 ) connector to a
Mini‐GBIC port connector. This procedure also applies to an LC cable connector shown in
(
Figure 4‐11 ). Refer to Figure 4‐10 as an example and proceed as follows:
1. Remove the protective covers (not shown) from the MT‐RJ fiber‐optic port on the Mini‐GBIC
and from the connectors on each end of the cable.
2. Insert the MT‐RJ cable connector into the Mini‐GBIC until it clicks into place.
.
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 cleaning swab saturated with optical-grade isopropyl alcohol may also
be used to clean the ends.
Precaución: No toque los extremos de los cables de fibra óptica y evite su contacto con el polvo,
la suciedad o con cualquier otro contaminante. Si los extremos de los cables se ensucian, es
posible que la transmisión de datos se vea afectada. Si nota que los extremos de los cables de
fibra óptica se ensucian, utilice aire comprimido para limpiarlos. También puede limpiarlos con un
estropajo embebido en alcohol isopropílico.
Note: To remove the MT-RJ cable connector, press on its release tab and pull it out of the
Mini-GBIC.
