We describe an optical transmission system for uncompressed Super High-Vision (SHV), which is an extremely high resolution video system with 4000 scanning lines and 22.2 multi-channel audio. We transmitted an SHV signal composed of 16 HD-SDI signals a distance of 260 km through an existing optical fiber using four optical amplifiers and dense wavelength division multiplexing technology. Application of distributed Raman amplification to the system enabled the SHV signal to be transmitted up to 180 km without using optical relay amplifiers.
