Spectrum Series Multichannel Fiber Optic Digital Video/Audio Transmission System
Spectrum has been designed to operate with all of the major television standards. Spectrum allows the user to configure systems in numerous ways. Point-to-point or point-to-multipoint systems may be configured with multiple repeater locations, which do not compromise the quality of the received signal. In conjunction with Synchronous advanced DWDM technology, multiple systems may be carried over a single fiber. The system has full drop and insert capability, allowing channels to be added or dropped as required anywhere in the system.. Receiving locations may also function as repeater sites using the Spectrum drop and repeat system. Complex ring and protected ring architectures are made simple with the flexibility designed into the Spectrum.
System stability and performance parameters surpass analog systems. Maintenance costs are substantially reduced. Individual coder and decoder modules used in Spectrum include front panel video status indicators, which provide immediate visual information on the presence of signals. Signal level adjustments, if required, are conveniently located on the front panels
Spectrum multichannel systems are available with a variety of optical transmission options. The system can be configured for either 1310 nm or 1550 nm transmission. Utilizing dense wavelength division multiplexing, 128 or more channels of signals can be transported over a single fiber. Utilizing 1310/1550 WDM, a 16 channel full duplex link can be established. Both wavelengths support all system functions, including drop and repeat and repeat only. Other optional configurations, using Synchronous advanced 1550 nm DFB and Dense Wave Division Multiplex technology, allow the system to be configured for long distances without requiring electrical repeaters.
Spectrum incorporates advanced system platform management techniques. It is designed to allow the network provider the maximum flexibility in system design and configuration. The same chassis is used for transmit and receive. The Spectrum chassis contains a sophisticated microcontroller subsystem to facilitate the status monitoring and alarm functions. Two LCD displays and a keypad are used to provide access to information and parameters of the main chassis, power supplies and the plug-in modules. The left display shows a selection bar with choice of selections. The user can move through the selections using the left and right arrow keys adjacent to the display. The item selected is indicated by a flashing character.
