Single-mode fibers (SMFs) are expected to be widely deployed in future subscriber loop networks. There is great advantage in using the 800-nm region on SMF in addition to long wavelengths, thus taking advantage of available low-cost short-wavelength sources and receivers. At 800 nm, both the fundamental and first higher-order mode groups in standard 1300-nm optimized SMFs are well guided giving rise to large differential mode delays1,2 and to modal noise at fiber discontinuities. This paper discusses how to minimize these problems resulting in high-speed transmission over distances applicable to the local telephone exchange environment.
