CMC 4000 Series 1.218 GHz Horizontal Universal Digital Splitters

Reliability, quality, and performance define the Antronix CMC4000H series digital splitter. Our digital splitters have been designed specifically for today’s two-way broadband networks. Low intermodulation distortion and high port-to-port return band isolation prevent high-power cable modem signals from distorting neighboring port signals. Capacitively coupled F-ports block AC surges and prevent hum modulation. Additionally, our splitters are among the most robust in the industry. Every port on each CMC4000H series splitter can withstand 6 kV ring wave surges, while our proprietary ferrites remain ultralinear following several surges. To ensure years of reliable performance, Antronix’s splitters are encased in a zinc alloy diecast housing with nickel tinplating. The splitter ports are sealed to 15 psi and are SCTE compliant. The CMC4000H series splitters guarantee consistent performance over time and temperature.
