Summary :

A 400 Mb/s optical fiber fransmission system was designed for field trial using single-mode fibers. The system is targeted to 20 km repeater spacing using InGaAsP/InP DH laser diode (LD) and Ge-APD as an optical device. This paper describes the design philosophy for the single-mode fiber transmission system and the field trial results. The error rate performance is expressed by signal to noise ratio (SNR) for practical high-speed digital optical repeater, putting emphasis on LD mode partition noise. Based on the SNR analysis and results obtained from several preliminary experiments, the design procedures for the 400 Mb/s transmission system were clarified. Through the field trial, it has become clear that the 400 Mb/s optical transmission system is practically applicable to long-haul transmission systems.
