NETGEAR CM2500-100NAS DOCSIS 3.1 High Split Coaxial Cable

Overview

The CM2500-100NAS is a 2-port DOCSIS 3.1 high split coaxial cable designed for premium cable modem installations where you need reliable upstream and downstream channel aggregation. High split configuration divides the frequency spectrum to maximize bandwidth efficiency — frequencies below 42 MHz are reserved for upstream traffic, everything above for downstream — which means your modem can use more available channels simultaneously without interference. This cable is built for the NETGEAR CM2500 series and compatible DOCSIS 3.1-compliant equipment in enterprise and multi-unit residential deployments.

Compatibility

The CM2500-100NAS is designed for NETGEAR CM2500 cable modems and DOCSIS 3.1-certified infrastructure. Verify your ISP supports DOCSIS 3.1 and high split frequency operation before installation — older networks may require standard split cables instead. Consult your ISP or system operator for confirmation of high split capability in your service area.

Technical Specifications

Port Aggregation: Supports up to 17 channels — more channels available simultaneously means faster downstream speeds and better upstream responsiveness compared to standard DOCSIS 3.0 or lower split configurations. High Split Design: Optimized frequency band utilization across dual connection points. This configuration is essential if your ISP has upgraded to high split DOCSIS 3.1 infrastructure — using a standard split cable will leave bandwidth on the table and may not initialize properly on high split networks.
