Connecting to the Network
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 Gigabit Ethernet device at the other end of the segment. The receive strand of the applicable LC port connects to the transmit port of the fiber‐optic Gigabit Ethernet device.
Enterasys 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 LC cable connector to a fixed LC connector of an XFP, refer to Figure 3‐17 and proceed as follows:
Caution: Do not touch the ends of the
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.
1.Remove the protective covers (not shown) from the front panel LC fiber‐optic port (port 22 in this example) 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.
2.Insert the LC cable connector into the XFP LC connector until it clicks into place.
Note: To remove the LC cable connector, press on its release tab and pull it out of the XFP LC connector.
