Raman amplification is proposed as a solution to extend the reach of XG-PON, using 1210nm quantum dot lasers to amplify the upstream transmission. The reach extender provides 759mW of maximum power and shows high temperature stability. Measured Raman on/off gain of 14 dB accommodates transmission of a 1270nm signal over 50 km single mode fibre with a supported split ratio of 1:64. Transmission performed in burst mode shows no gain transients arising from stimulated Raman scattering.

Abstract

Raman amplification is proposed as a solution to extend the reach of XG-PON, using 1210nm quantum dot lasers to amplify the upstream transmission. The reach extender provides 759mW of maximum power and shows high temperature stability. Measured Raman on/off gain of 14 dB accommodates transmission of a 1270nm signal over 50 km single mode fibre with a supported split ratio of 1:64. Transmission performed in burst mode shows no gain transients arising from stimulated Raman scattering.
