The TRIAX TDC4 dSCR/Quad/Quattro Optical Converter is a flexible optical fibre conversion unit that supports SAT IF distribution over passive fibre links with minimal signal loss (about 0.3 dB per 1000 m). It can be configured as a standard Quattro converter or switch to a dSCR/Quad output mode, providing adaptable output options for satellite, terrestrial and radio services from a central feed point. Its space‑saving design replaces bulky coaxial cables with a single optical fibre for efficient long distance distribution.
