Abstract

This paper describes two different methods of overcoming dispersion on step-index fiber in the 1550-nm window: (a) dispersion-compensating fiber (DCF) with standard 10-Gbit/s binary transmission and (b) multilevel coding to reduce the spectral width of the signal. These two systems were combined to form a 20-Gbit/s WDM system with 1.3-nm channel spacing. The experimental work was performed on installed step-index fiber within the BT network with λ0 = 1320 nm, 15.1-ps/nm/km average dispersion at 1550 nm, and 0.27-dB/ km average fiber loss at 155 nm.
