Abstract

Optical fiber waveguides are being employed in several communication systems of moderate bandwidth and length. For example, Nippon Electric Company(I) has reported on a 7.6 Mb/s system operating over 2.3 km using SELFOC fiber waveguide while U. S. Naval Electronics Laboratory Center (2) has installed a 44 MHz closed circuit TV system and a 108 kHz, 6 telephone system both several hundred feet long. GTE Labs(3) reported on a short length T-2 (6. 3 Mb/s) system. Others will be described in this conference. (4) The full potential afforded by the characteristics of optical fiber waveguide transmission such as wide bandwidth, noise immunity, small size and weight has not been reached as yet. More studies of its feasibility in various applications are required, and here the suitability of wide-band signal transmission over optical fiber waveguides is examined.
