Python Plus
Python Plus is our answer to lowering the cost of digital video and fiber distribution, eliminating concerns about distance, interference or ground loop issues. With today’s demanding market — technology shifting to IP and the constant increase in bandwidth demands driven by 3G and 4K UHD — Python Plus simplifies transport solutions. Each unit can transport a mix of digital and IP cameras or virtually any digital video transceiver through fiber or copper cables.
