DHT3 series is the next generation of DOCSIS-HMS transponders and is the first DOCSIS 3.0 Transponder. A Spectrum Analyzer is built in to each transponder and therefore each power supply location becomes an [always on] test point for not only power supplies

but also for the downstream broadband HFC network.

DHT3 series have an integrated web server that provide up to the minute display of all power supply metrics and states. Also available in a modem-only configuration (DRM3).

DHT3 series uses field-proven DOCSIS® and EuroDOCSIS® integrated circuits and is built with components rated for extreme temperatures. It sets the industry standard for quality and performance.
