Optical fiber transmission systems with extremely long repeater spacing are very attractive for various applications both in land and undersea communication systems. This paper describes the results of transmission experiments, using low-loss fibers in the 1.2-1.6 μm wavelength region. Graded-index optical fibers having an optimum profile at 1.27 μm were manufactured in cables. Average bandwidth was 1,275 MHz-km, and the average optical loss was 0.6 dB/km. The 52.6-km and 62.3-km repeater spacings were realized at 100 Mb/s and 32 Mb/s transmission, respectively, using InGaAsP/InP LD and Ge-APD. The 21.5-km and 12.0-km repeater spacings at 32 Mb/s were also realized by 1.2μm and 1.5μm LEDS, respectively. |
