These Diplex Filters are designed for the new DOCSIS 3.1 frequencies but are also compatible with standard 1000 MHz system.
They feature a small compact housing that has a solder back for 120 dB RFI shielding. Two models are available to fit different reverse frequencies 5-85 MHz and 5-42 MHz for use depending on system requirements.
Both models pass to 1222 MHz so they are future proof as systems increase bandwidth.
