4Cable Aims to Adjust the Return Remotely

4Cable TV's (OTCQB:CATV) DSR No Diplexer Nodes are now in production. They're designed to allow cable operators to adjust the return bandwidth capacity of to-the-home coaxial cable lines directly from a central network hub.The nodes have up to 85 MHz of dynamically scalable return bandwidth, which is intended to allow cable operators to adjust their return bandwidth by modifying the downstream channel lineup. It's also designed to remove group delay problems in the return transmission channel (T-12) and make the unusable cross-over channel (T-13) available for the return signal.The new nodes use the company's PowerMiser system and are also designed to be adapted to run on solar powered cable systems.
