BNC Balun – RJ45 to 2x BNC (F)
The BNC Balun – RJ45 to 2x BNC (F) is a compact impedance converter designed to enable seamless transmission between 75Ω coaxial cable and 120Ω balanced twisted pair cable in G.703 telecommunications networks.
Supporting ITU-T G.703 2.048Mbit/s applications, the balun converts signals between dual female BNC connectors and an RJ45 interface, providing a simple and reliable solution for connecting legacy coaxial infrastructure to structured cabling systems. With excellent signal integrity, low insertion loss and high crosstalk isolation, it is ideal for E1 transmission circuits, telecommunications equipment and network upgrades.
The compact housing is suitable for rack rooms, communications cabinets and telecom installations, offering quick installation without requiring external power. Designed for professional telecommunications environments, the balun provides dependable impedance matching and signal conversion for voice and data applications.
