32 digital uncompressed TV channel distribution via 8 HDWDM channels

摘要

The performance of a demonstrator for the distribution of 32 digital uncompressed TV channels using HDWDM has been examined. For the transmission 8 optical wavelengths have been used spaced by 2 nm in the 1529-1543 nm range carrying a data rate of 8/spl times/622 Mbt/s. Without optical amplifier a splitting factor of 16 has been obtained for the PON with low crosstalk and polarization sensitivities. The demonstrator is the distributive part of a combined demonstrator including broad- and narrowband interactive services.
