Transmission of HDTV and Audio Signals over One Single-Mode Fiber
Until recently, equipment available for fiber-optic transport of high-definition television (HDTV) over limited distances has used three separate fibers for transmission of the color components and a fourth for audio. Shortcomings of this approach are poor color registry, resulting from differences and variations in propagation delay, and the high cost of providing multiple fibers. Compressed digital HDTV codec algorithms required for digital transmission (Broadband Integrated Services Digital Network [BISDN]) at an output bit rate of 150 to 600 Mbits/sec (SONET STS 3 to 12) are under laboratory study, but commercial availability appears to be several years away. This article describes the transmission of uncompressed HDTV signals and digital audio on one single-mode fiber incorporating components available today, such as wavelength division multiplexing and pulse-frequency modulators. Critical measurements made on a laboratory model to verify systems analyses are reported.
