This is a Belden H121C00 coaxial cable for cable broadband communication networks.
The H121C00 CATV Drop Cable is a coaxial cable designed for broadband communication networks and complies with European standards EN 50117 series. The datasheet describes its construction, including a solid bare‑copper inner conductor, gas‑injected PE dielectric, foil‑and‑braid outer conductor, and a PVC jacket.
Electrical characteristics such as a 75 Ω ±3 Ω characteristic impedance, 53 pF/m capacitance, and 84 % velocity of propagation are listed, along with mechanical data like temperature ranges, minimum bending radius, and cable weight. Ordering information, marking, and packaging details are also provided.
