Abstract

In the last year or two there has been spectacular progress in developments relating to single-mode fibers. In terms of fabrication it is now possible to achieve continuously drawn lengths¹ of 100 km having losses of only a few tenths of a dB/km. The conditions under which bend and microbend losses can be minimized have been indicated by various analyses² and have been realized in practice so that experimental transmissions over 100 km have been reported.³
