The first generation of optical communication systems employed inside their optical transmitters GaAs semiconductor lasers operating at a wavelength near 850 nm. The optical bit stream was transmitted through graded-index multimode fibers before reaching an optical receiver, where it was converted back to the electric domain using a silicon photode...
By 1990 the attention of system designers shifted toward using three new ideas: (1) periodic optical amplification for managing fiber losses, (2) periodic dispersion compensation for managing fiber dispersion, and (3) WDM for enhancing the system capacity. As seen in Fig. 8.9, the WDM technique employs multiple lasers at slightly different waveleng...
It should be clear from Fig. 8.8and the preceding discussion that the adoption of WDM during the fourth generation of optical communication systems was a disruptive technology. Fortunately, its adoption coincided with the advent and commercialization of the Internet around 1994. Just as the explosive growth of websites all around the world increase...
