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.
