Smooth communication: The RJ12 telephone line uses pure copper core wires, which have better conductivity, more stable transmission, and no delay, providing you with a clearer and smoother communication experience. Widely used: RJ12 telephone lines have a wide range of applications, such as telephone lines, high-frequency radios, fax lines, printer lines, radio systems, etc. Good elasticity: The upgraded version of the spring cable has good elasticity, allows for easy expansion and contraction, and can be quickly retracted after stretching to avoid entanglement. Gold-plated contacts: Each wire has a 50 micron gold-plated contact connector, providing the strongest connection and corrosion resistance. Cable length: The elongation rate of the spring cab.
