Unrepeatered 40-Gbit/s RZ single-channel transmission at 1.55 /spl mu/m using various fiber types

Summary form only given. The increasing request for broadband communication services demands for telecommunication networks offering line capacities exceeds those of existing facilities. One way to increase the transmission capacity of a given fiber link is TDM. When installing new transmission links, network operators have to decide which fibers will best meet future traffic requirements. 40-Gbit/s TDM transmission at 1.55 /spl mu/m over standard single-mode fiber has been reported using various dispersion-compensating techniques: passive dispersion compensation with dispersion-compensating fibers or chirped Bragg fiber gratings and active dispersion compensation by mid-span spectral inversion. In this paper we investigate experimentally and theoretically 40-Gbit/s TDM transmission over trueWave/sup TM/ fiber (2.3-ps/nm/km chromatic dispersion), standard fiber (16-ps/nm/km), and dispersion-shifted fiber (0.1-ps/nm/km).
