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.

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.
