Fiber issues for nontraditional wavelength bands

Summary form only given. The rapid increase in bandwidth demand is driving systems toward utilizing more of the roughly 50 THz optical bandwidth available in a fiber. This paper explores fiber issues and system opportunities for using wavelengths outside the traditional 1310 and 1550 nm windows, including the L-band the S-band, and, with new zero-OH fibers, the 1400 nm region
