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-modeb.Multimode11. 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.Throughputb.Costsc.Connectord.Noise immunitye.Size and scalabilitySMF (Single-Mode Fiber)1.Describe SMF (single-mode fiber).2.Explain the benefits of SMF.3.Describe the drawback of SMF.4.Use Figure 3-36 to illustrate transmission over single-mode fiber-optic cable.MMF (Multimode Fiber)1.Describe MMF (multimode fiber).2.Explain the common uses of multimode fiber.3.Describe the benefits of MMF.4.Describe the drawback of MMF.5.Use Figure 3-37 to illustrate transmission over multimode fiber-optic cable.6.Describe the benefits of MMF.7.Describe the drawbacks of MMF.
