Chapter (3) Networking Media and Data Link Layers Protocols

Figure 3-9 shown a type of fiberoptic cable in different sectional views The
following summarizes the features of fiber-optic cables:
• Speed and throughput—More than 1 Gbps

• Average cost per node—Expensive

• Media and connector size—Small

• Maximum cable length—More than 10 kilometers (km) for single mode; up to 2
km for multimode

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.

Figure 3-10 shown a type of fiberoptic SC Connector

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.
