This 1‑channel bidirectional 12G‑SDI fiber optic transmitter, developed by our company, enables simultaneous bidirectional transmission of 12G‑SDI video signals. Compact and lightweight, it fits fixed room and mobile on‑site use, cutting installation and carrying costs. Adopting professional SDI driver chips, it supports signal equalization and clock recovery, delivering latency‑free, distortion‑free transmission with strong anti‑interference for stable output in complex environments. Its key highlight is bidirectional video transmission without redundant devices, simplifying link setup for live return, remote monitoring, conference interaction and more. With industrial‑grade stable design, it supports long‑term non‑stop operation, balancing durability and practicality.
Ideal for broadcasting, live sports, security monitoring, multimedia conferences, it’s a cost‑effective choice for stable transmission.
