Mini 3G-SDI Fiber Converter Bi-directional HD-SDI 80km Hot Plug

Model: LNK-M3G-BI20 Series

 Product Description & Overview

The Mini Bi-directional HD/3G-SDI to Fiber Converter provides a compact yet powerful solution for

high-quality video transmission, enabling reliable 1080p signal delivery over fiber optic infrastructure.

This system consists of a matched transmitter and receiver pair that supports a single-channel bi-

directional 3G/HD-SDI video stream with embedded audio, making it ideal for space-constrained

installations without compromising performance. The converter leverages advanced fiber optic

technology to ensure full digital non-compression broadcast-level transmission, maintaining

pristine signal integrity even over extended distances while handling all SMPTE pathological

test patterns for maximum reliability.

Designed with versatility in mind, this miniature converter features a robust all-digital architecture

that eliminates the need for signal compression, thereby preserving original video quality without

introducing latency or artifacts. Its bi-directional capability allows for flexible deployment in point-to

-point links where video and control signals must travel in both directions over a single fiber pair.

The device's compact form factor makes it particularly suitable for integration into flypacks, camera

backplates, and tight equipment racks commonly found in mobile production units and modern broadcast

facilities.

This high-performance converter is engineered to meet the rigorous demands of professional

applications, finding extensive use in broadcast studio links, live event production, high-security

surveillance systems, and corporate video conferencing environments. By converting electrical

SDI signals to optical format, the system provides complete immunity to electromagnetic interference

and ground loop issues, ensuring stable operation in electrically noisy settings. The solution offers

broadcasters, security integrators, and AV professionals a reliable, high-quality method for extending

HD and 3G-SDI video connections while maintaining the simplicity and efficiency required in today's

fast-paced production landscapes.
