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 cable,
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 cable 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 cable 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 cable selection depends on SFP module. You must specify the desired SFP
modules when you purchase a firewall. Otherwise, the fiber cable is not provided.
