3.1 Lasers Telecoms
Lasers for telecom applications emit in the transmission windows of 1.3 or 1.5 µm optical fibers. They are used for long-distance point-to-point links, metropolitan networks and access networks. Since the distances involved are at least always greater than ten kilometers, the transmission medium is always a single-mode fiber. Since fiber losses and dispersion are wavelength-dependent, the source's spectral range must be well defined to minimize degradation of the transmitted...
