Mini Bi-Directional 3G-SDI Fiber Converter 80km 4-Ch Audio Hot-Pluggable -20~70°C

SDI Fiber Converter Overview:

The LNK-M3G-BI20 Series represents an innovative miniaturized fiber optic solution engineered for space-constrained professional video applications. This compact converter enables simultaneous bidirectional transmission of 3G/HD-SDI signals with embedded audio over a single fiber optic cable, providing exceptional flexibility in system design and installation.

Utilizing advanced digital processing technology, the system maintains full broadcast-level quality with uncompressed signal transmission while effectively handling all pathological patterns to ensure reliable performance. The complete transmitter and receiver set delivers pristine 1080P resolution video with precision timing and synchronization, making it ideal for mission-critical video applications.

Designed with a space-efficient form factor, this converter is particularly suitable for mobile production units, broadcast fly-packs, and permanent installations where rack space optimization is essential. The robust construction and sophisticated error correction mechanisms guarantee stable operation in demanding environments, from controlled studio settings to challenging field conditions.

This versatile solution finds extensive application across multiple industries including security and surveillance networks, professional video conferencing systems, broadcast facilities, and live event production. Its bidirectional capability enables efficient two-way video communication, while the compact design allows for seamless integration into existing infrastructure without compromising performance or reliability.
