Abstract

The system performance of future high-speed TDM-systems beyond 10 Gbit/s is severely degraded by the large chromatic dispersion when transmitted over the already installed standard single-mode fiber (SMF) network at 1.55 µm. An unchirped 40 Gbit/s conventional NRZ-modulated signal will suffer a 1 dB dispersion penalty after about 4 km. To cope with this stringent limitation the most attractive ' schemes are Dispersion-Compensating Fibers (DCFs) and Optical-Phase Conjugation (OPC), which both have already shown their potential in various experiments [1-6]. In particular a 10 Gbit/s transmission over 2245 km standard fiber with the use of DCFs was reported [1]. It is the goal of the present work to conclude on the suitability of both concepts for future high speed systems operating at 40 Gbit/s over the embedded standard-fiber.
