9. Note that there are different varieties of fiber-optic cable depending on its intended use and the
manufacturer.
10. Introduce the two categories of fiber-optic cable:
a. Single-mode
b. Multimode
11. Use Figure 3-33 to illustrate a ST (straight tip) connector.
12. Use Figure 3-32 to illustrate a SC (subscriber connector or standard connector).
13. Use Figure 3-34 to illustrate a LC (local connector).
14. Use Figure 3-35 to illustrate a MT-RJ (mechanical transfer registered jack).
15. Discuss the characteristics of fiber optic cable:
a. Throughput
b. Costs
c. Connector
d. Noise immunity
e. Size and scalability
SMF (Single-Mode Fiber)

Tip
Point out that the arrangement of the pins on both connectors resembles a
sideways letter D.
7. Discuss where RS-232 connections are likely to be used in today’s networks.
8. Describe how the termination points on RS-232 cables can be arranged in various ways:
a. Straight-through
b. Crossover
Structured Cabling
1. Define a cabling plant.
2. Describe the TIA/EIA joint 568 Commercial Building Wiring Standard.
3. Use Table 3-2 to illustrate TIA/EIA specifications for backbone cabling.
4. Use Figure 3-42 to illustrate the different components of structured cabling in an enterprise from a bird’s
eye view.
5. Use Figure 3-43 to illustrate how structured cabling appears within a building.
