Note:
In making network cables, shielded cables are preferred for the sake of
electromagnetic compatibility.
2) Cables for optical Ethernet interfaces
For an optical Ethernet interface, you can choose the appropriate fiber-optic,
single-mode or multi-mode, depending on the 1000Base-FX SFP optical transceiver
you are using (see Table 1-6 for fiber options). Because all the available optical
transceivers use LC optical connectors, your must use the fiber-optic with LC fiber
connectors. All the optical transceivers are hot-swappable.
Note:
A fiber connector, as defined by the International Telecommunications Union (ITU), is a
passive component that connects two or more fiber-optic segments stably but not
permanently. Fiber connectors are indispensable to an optical communication system,
making it possible to connect and disconnect optical channels.
Following are several fiber connector types:
FC: A round optical connector with screw threads
ST: A round plug-in optical connector
SC: A square optical connector
MT-RJ: A square optical transceiver
LC: A compact optical connector developed by Lucent
Note:
The fiber-optic selection depends on SFP module. You must specify the desired SFP
modules when you purchase a security gateway. Otherwise, the fiber-optic is not
provided.
