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.
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
Figure 3‐14).
The following procedure describes how to connect an MT‐RJ cable (Figure
to a Mini‐GBIC port connector. This procedure also applies to an LC cable connector
shown in (Figure 3‐14). Refer to Figure
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.
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.
2. Insert the MT‐RJ cable connector into the Mini‐GBIC until it clicks into place.
Note: To remove the MT-RJ cable connector, press on its release tab and pull it out of the
Mini-GBIC.
