Abstract
This paper demonstrates a 10 Gbit/s wavelength converting access network
utilising a centralised optical processing unit that consolidates multiple low cost PONs
onto a DWDM backhaul. The centralised processing unit functions as an amplifier,
wavelength converter, pre-chirping stage and optical burst equaliser to map legacy PONs
onto a DWDM grid for efficient backhaul transmission and to ease the dynamic range
requirement of the 10 Gbit/s burst-mode receiver at the optical line termination (OLT).
The dispersion limited performance, wavelength tolerance, and burst-mode dynamic range
are evaluated demonstrating a maximum range of 62 km for 20 nm of input wavelength
variation and a dynamic range of up to 22 dB.
