Pp. Iannone et al., ENHANCED PRIVACY IN BROADCAST PASSIVE OPTICAL NETWORKS THROUGH THE USE OF SPECTRAL SLICING IN WAVE-GUIDE GRATING ROUTERS, IEEE photonics technology letters, 9(7), 1997, pp. 1044-1046
We have measured the ability of a third party to intercept upstream me
ssages in both passive splitter-based and waveguide-grating router-bas
ed broadcast passive optical networks. Bit-error-rate (BER) measuremen
ts 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 develop
ments.
