1.22GHz broadband user amplifier is a bidirectional transmission amplification device developed by referencing industry standards and drawing on the advantages of domestic and foreign products. It has four port outputs and supports DOCSIS3.1 . The frequency points can be selected from 42/54,and 85/102MHz.Power outages can cause important voice and data signals to be interrupted. This product can have an independent home phone port that provides uninterrupted lifeline service.
Features:
★Small size
★Passive home phone port
★Stainless steel grounding and installation performance indicators are superior
★Sealing and waterproof performance are good
★Flexible and convenient to use
★Good performance price ratio
