Chapter 7. Long-Haul Optical Networks
This chapter covers the following topics:
Light has an information-carrying capacity that is 10,000 times greater than the highest radio frequencies in the electromagnetic spectrum. Nowhere is capacity more important than in long-haul networks, where communications converge between great masses of people. Since the 1980s, long-haul networks have followed the light to create today’s capacious long-haul optical networks.
Long-haul optical networks benefit from two complementary ascendancies: the speed of optical modulation and the density of ...
