Harmonic has introduced the SUPRALink 1,550 nm DWDM transmission system, designed to enable cable service providers to re-use their existing optical fiber network to more cost-effectively deliver increased bandwidth to subscribers. Incorporating patent-pending technology, the solution is designed to deliver up to a four-fold increase in fiber reach over 1,310 nm systems. It is designed to support up to eight wavelengths per single fiber over link distances of 40 km with optical amplification and 25 km without optical amplification, for up to 1 GHz of both digital and analog content per wavelength.
An eight-wavelength SUPRALink system delivers an increase in reach of 2.5 to 4 times when compared to eight-wavelength 1,310 nm WDM systems. The system can be scaled in one-wavelength increments and includes optical transmitters, multiplexers, de-multiplexers, and amplifiers.
