Title: | Overmodulated single-octave subcarrier multiplexed optical networks for multichannel FM video distribution | Authors: | Mendis, F.V.C. Tan, B.T. |
Issue Date: | 1990 | Citation: | Mendis, F.V.C.,Tan, B.T. (1990). Overmodulated single-octave subcarrier multiplexed optical networks for multichannel FM video distribution. Conference Record - International Conference on Communications 2 : 404-408. ScholarBank@NUS Repository. | Abstract: | In subcarrier multiplexed (SCM) multichannel FM video systems, the carrier-to-noise ratio per channel may be increased by overmodulating the laser diode source. The authors predict the overmodulation that may be employed in practice for single-octave SCM transmission in passive optical networks. It is shown that optical modulation indices (OMI) exceeding 500% may be used if the number of subcarriers is large. A 47-dB signal-to-noise ratio (with 4-dB margin) is deemed sufficient for acceptable picture quality in cable distribution systems, while a 56-dB value would be required for long-distance point-to-point optical links. | Source Title: | Conference Record - International Conference on Communications | URI: | http://scholarbank.nus.edu.sg/handle/10635/81652 | ISSN: | 05361486 |
