Abstract
An 800-Mbit/sec optical fiber transmission experiment at the 1.05-μm wavelength is reported. Single frequency output of a LiNdP4O12 laser is modulated with a guided-wave LiNbO3 modulator in an NRZ code and is transmitted through 4-km long single-mode fibers. The minimum receiving level is −30 dBm using a Ge avalanche photodiode. It is shown that, since the repeater spacing is limited by loss rather than dispersion in the present system configuration, a more than 10-km repeater spacing seems to be feasible. Distinctive features and problems associated with the system and constituent devices are discussed.
