From International Fiber Systems (IFS) the VT/VR73230 32-channel digitally encoded video multiplexing system uses course wavelength division multiplexing (CWDM) technology and 8-bit digital encoding. CWDM technology enables a much higher number of channels on one optical fiber compared to the existing WDM technology commonly used. The unit offers true digital performance that transmits up to 32 real-time video channels with a consistent signal-to-noise ratio up to the maximum optical path loss of the system.
