Abstract

Polarization hole burning1 (PHB) can reduce the received signal-to-noise ratio (SNR) of a data signal propagating through a long chain of erbium-doped fiber amplifiers (EDFAs). PHB can cause the amplified-spontaneous-emission (ASE) noise to accumulate faster in the polarization orthogonal to the signal than would be predicted according to simple ASE-noise-accumulation theory.2 In this paper we show that scrambling the state of polarization (SOP) of the transmitted signal significantly reduces the transmission impairment caused by PHB. We demonstrate SNR improvements of 1 and 2 dB for 5-Gbit/s 4500- and 8800-km systems, respectively.
