First Demonstration of a Full C-Band Tunable WDM-PON System with Novel High-Temperature DS-DBR Lasers

Abstract

We demonstrate automatic operation of a cooler-less tunable-laser based WDM-PON system. Using a pilot-tone based overhead channel and centralized wavelength locking scheme, 1 Gb/s and 10 Gb/s data transmission is demonstrated in a multi-user set-up.
