The connector shapes used in networking setups are
listed in table 2-1. Figure 2-4 shows examples of
connector shapes.
FIBER-OPTIC CONNECTORS.— Like
electrical cable connectors, different types of fiber-
optic connectors have different kinds of attachment
mechanisms. The actual attachments between ferrule
shells may be made by threading, snapping, or clicking.
Table 2-2 lists the most commons types of fiber-optic
connectors.
Table 2-2.—Fiber-optic connectors.
In addition to attachment mechanisms, fiber-optic
connectors differ in the following ways:
l
l
l
The size of the ferrule.
Whether the connector can be keyed. This is the
technique for making a connector asymmetrical,
usually by adding a notch or plug, making it
impossible to plug the connector in wrong.
The number of matings the connectors can
handle without producing unacceptable signal
loss.
