Paper Abstract

Raman amplification has been one of the enabling technologies employed to push the capacity x distance product in terrestrial DWDM systems. Due to its broad gain spectrum and the commercial availability of desired Raman pump wavelengths, more than 100-nm bandwidth is made possible covering the low loss window of silica fibers. In addition, distributed Raman amplification in transmission fibers and/or dispersion-compensating fibers (DCF) can significantly improve the system signal-to-noise ratio. In this talk, we will discuss the advantages and issues of Raman amplification, including pump-pump and pump-signal crosstalk, and their impact on the design of next generation fibers. Recent transmission experiments over Raman enabled fibers will be presented. Optimization of the system performance by allocating the Raman gains in co-, counter- and DCF-pumping will also be discussed.
