Abstract
We present an analytical model for performance of a transmission system in
which Raman amplification is employed. We perform a network value analysis on the
basis of that model and show that use of Raman amplification in 40-Gbit/s
dispersion-managed systems can realize a savings in capital expenditure of ~20%
compared with erbium-doped fiber amplifiers for a full network build of a large U.S.
carrier.
