T F Optical communication uses infrared light. C band is used commonly because of EDFAs. Graded index fiber has a lower modal dispersion than step index fiber Plastic fiber is cheaper than glass fibers Dispersion shifted fiber is used in DWDM systems If a signal can travel 1600 km at 10 Gbps, due to PMD it can travel 400 km at 40 Gbps Fiber.

The fourth generation of fiber-optic communication systems used optical amplification to reduce the need for repeaters and wavelength-division multiplexing to increase data capacity. These two improvements caused a revolution that resulted in the doubling of system capacity every six months starting in 1992 until a bit rate of 10 Tb/s was.

either end of the optical link and at present the signal processing is usually performed electrically.* The optical carrier may be modulated using either an analog or digital information signal. In the system shown in Figure 1.1(b) analog modulation involves the variation of the light emitted from the optical source in a continuous manner.

The advantage of an optical fiber for communications is that it has a bandwidth of approximately one terahertz, and can propagate signals over continental and even global distances when assisted by optical amplifiers. These amplifiers are currently separated more than ~80 km, and this separation is steadily increasing as technology improves.

1.1 Introduction. It is very difficult to fit a subject like semiconductor laser for optical communications into a single book and have it remain accessible. It spans an enormous range of areas, including optics, photonics, solid-state physics, and electronics, each of which is (by itself) worthy of several textbooks.
