This compact broadcast converter is designed to extend SDI signals over extremely long distances by converting electrical SDI into optical fiber and back again in real time. It operates bidirectionally, meaning SDI can be converted to fiber and fiber to SDI simultaneously, even when each direction uses a different video standard. This makes the device ideal for large venues, studios, OB trucks and campus‑wide installations where copper cabling is impractical or unreliable over long cable runs. 

Support for full 12G‑SDI ensures compatibility with all SD, HD and Ultra HD formats up to 2160p60, including both Level A and Level B equipment. Automatic multi‑rate detection allows the converter to instantly adapt to incoming signals without manual configuration, reducing setup time and minimizing the risk of format mismatches. The internal reclocking circuitry helps maintain signal integrity across long distances, ensuring stable and reliable transmission even in demanding broadcast environments. 

The optical interface is based on a standard SFP socket, allowing the use of widely available 3G, 6G or 12G‑SDI optical fiber modules depending on the required distance and format. By using the same low‑cost fiber cables commonly deployed in IT networks, SDI signals can be transported over distances of up to approximately 16 km, far exceeding the limits of traditional coaxial cabling. Embedded audio is carried transparently with support for up to 16 channels, preserving full program integrity throughout the conversion process.

Designed for reliability and ease of integration, the unit features a robust metal enclosure suitable for permanent installation or portable use. There are no user controls on the device itself, ensuring consistent operation once installed. Configuration and software updates can be performed via USB using Blackmagic utilities on macOS or Windows systems. Power is supplied by the included universal 12 V power supply with international socket adapters, and a cable tie point is provided to prevent accidental disconnection in critical setups.

By combining bidirectional operation, long‑distance optical transport and broad format support, this converter provides a simple and effective solution for extending SDI workflows into fiber‑based infrastructures without compromising broadcast quality.
