Abstract :
We have experimentally demonstrated symmetric 40Gb/s TWDM-PON with long passive reach and high power budget. Directly-modulated lasers (DMLs) are used as both downstream and upstream lasers to reduce the system cost, and optical reshaping filter is used to manage the chirp of the DMLs for all the upstream and downstream channels, enabling long distance transmission without dispersion compensation. The power budget is as high as 43 dB for 100-km passive reach, supporting 64 users.
