Abstract

Subcarrier Multiplexed (SCM) systems have received a considerable amount of interest, mainly in areas such as radioon-fiber systems and multi-channel video distribution. SCM systems, which use double sideband transmission, however experience high dispersion penalty especially in long distance transmission. Several techniques have been proposed to improve this, one of which is optical single sideband modulation. Recently, a tandem single sideband (TSSB) technique that enables transmission of different channels on each of the two sidebands was proposed. This effectively doubles the bandwidth efficiency while improving the dispersion penalty. In this paper, we demonstrate a novel technique to transmit and receive in the proposed TSSB technique using orthogonal carriers. Two channels of 200 Mb/s NRZ data were used to modulate a pair of orthogonal RF carriers and subsequently transmitted using the TSSB technique. Although the RF spectrum of the two received channels overlaps one another, they can be separated using quadrature demodulators. In this paper, we report simulation results of error free transmission for two 200 Mb/s channels using orthogonal carriers in TSSB systems.
