A major impetus for the development of high performance solid state optical sources is the advance in optical fiber technology. Present day off-the-shelf optical fibers offer a loss of below 1 db/km, and bandwidths from (depending on the fiber type) 1 GHz-km to 10 GHz-km. Two main categories of fibers exist today: those that operate at 0.8 um, and at 1.3 um - 1.5 um optical wavelength. In each of the above categories, there are two fiber types - multimode and single mode. By far the most common optical fibers produced today are of two types: multimode fiber at 0.8 um, and single mode fiber at 1.3 um. Single mode fibers in general offer much higher bandwidth than multimode fiber. However, single mode fibers at 0.8 um are not produced in any substantial quantity and, in this author's opinion, with unsatisfactory performances in terms of backscattering loss. Hence, for the majority of applications in photonic measurements where streak cameras are used for data recording, 0.8 um multimode fiber systems appear to be the nominal transmission medium in the near future.
