Abstract
We propose a novel high-power (up to 1.9 W) and low relative intensity noise (RIN) laser structure for effective first- and higher order distributed Raman copumping. RIN characterization and bit-error-rate measurements at 10 Gb/s point out RIN-penalty free transmission up to 25 dB of ON-OFF copropagating Raman gain. This new copumping technology can provide sensible span reach enhancement in long-span unrepeated WDM transmission systems in a simple and effective way. © 2006 IEEE.File in questo prodotto:
