Abstract :
Subcarrier-multiplexed (SCM) lightwave systems for near-term, potentially low-cost video distribution are considered. An experiment is reported in which a single wavelength, carrying simultaneously 622-Mb/s data, ten C-band satellite channels between 950 and 1450 MHz, and three HDTV signals from 1.5 to 2.1 GHz, via amplification by a packaged traveling-wave laser amplifier (TWLA) was transmitted through 10 km of a single-mode (SM) fiber and split 128 ways optically. No optical filter was used after the amplifier. At the receiver, with a 3-dB power margin, the data bit error rate (BER) was 10/sup -9/ and carrier-to-noise ratios (CNRs) of 16.9 dB and 12.9 dB, respectively, were measured for the HDTV and satellite signals. The effects of TWLA-introduced noise degradations on BER and CNR at various input power levels to the TWLA are also quantified.<>
