Abstract :
We have measured the ability of a third party to intercept upstream messages in both passive splitter-based and waveguide-grating router-based broadcast passive optical networks. Bit-error-rate (BER) measurements at 150 Mb/s indicate that privacy is enhanced by at least 14 dB in the router-based network, and will improve further with router developments.
