3.3.2 Connectors

Connectors are attached to the fiber ends so that the fibers can be connected to the
ports on the transmitter and receiver. The most common type of connector used with
multimode fiber is the subscriber connector (SC), as shown in Figure 3-10.

On single-mode fiber, the straight tip (ST) connector, as shown in Figure 3-11, is
frequently used. With SC and ST, there is one connector for each fiber. Newer connectors
combine the send and receive fibers into one modular connector, comparable in size to an RJ-
45, to save space.

3.4Wireless Networking

When the computer was first introduced to the world, it was affordable by only large
corporations, governments, and universities. From the first building-sized devices with
minimal computing power to those that fit in the palm of a person’s hand, huge leaps in
technology have occurred. The same is true on the connectivity side of the industry. The
advantages are speed, reliability, and to a certain extent convenience. Physical connectivity
