Know before you buy
Yes, the CMC2004H is designed for two-way multimedia communications, making it fully compatible with cable modems, telephony, and digital broadcast signals including QAM and QPSK.
No, this is a passive device. It does not require electricity to function and relies entirely on the signal provided by your cable line.
Each port is engineered to withstand multiple 6 kV ring wave surges, meeting IEEE C62.41 Category A3 standards to help safeguard your connected devices from electrical spikes.
While the zinc alloy housing is durable and corrosion-resistant, these splitters are typically intended for indoor or protected enclosure use. If installing outdoors, ensure they are housed in a weather-sealed box.
These splitters support a bandwidth of 5-1002 MHz, which covers the standard frequency range required for most cable television and broadband internet services.
Optimized return band isolation prevents high-frequency signals from your cable modem from interfering with your forward transmissions, which helps maintain a stable and clear connection for all your devices.
