1080P Bi-directional HD-SDI Fiber Converter Hot-Swap & 40km over Single Fiber
LNK-MHD-BI20 Series Mini-type Bi-directional HD-SDI Fiber Converter supports 1-Channel Bi-directional HD-SDI Video (audio embedded) via fiber optical cable. Bi-directional HD-SDI Video over Fiber Converters includes one transmitter and one receiver for 1080P HD-SDI signal.
Revolutionary Bi-Directional Design: Video & Audio on a Single Fiber
Cut your fiber infrastructure costs in half with our groundbreaking Bi-directional HD-SDI Fiber Converter. Unlike conventional solutions that require separate fibers for send and receive paths, our innovative technology transmits and receives full 1080P HD-SDI video with 4-channel embedded audio over a single fiber strand. This revolutionary Bi-directional HD-SDI design not only reduces fiber core consumption by 50% but also dramatically simplifies cable management in crowded conduits and patch panels. Ideal for broadcast studios, live event production, and security systems, it delivers complete broadcast-level, uncompressed signal integrity while optimizing your entire network architecture.
Set-and-Forget Reliability: 40km Transmission with Industrial-Grade Stability
Engineered for mission-critical applications, this converter guarantees flawless performance over extreme distances and in varying environments. It achieves stunning long-distance transmission up to 40 kilometers without any signal degradation, making it perfect for connecting remote camera locations in stadiums, campuses, or city-wide surveillance networks. Advanced automatic cable equalization and reclocking technologies continuously clean and strengthen the signal, ensuring broadcast-quality integrity from end to end. Built with an ultra-broad temperature range (0℃~+55℃) and featuring a wide optic dynamic range that requires no manual adjustment, it delivers true ‘set-and-forget’ reliability for 24/7 operation in both controlled and challenging environments.
Application
Long-Distance Broadcast & Live Event Links: Perfect for outside broadcast (OB) vans and live sports production, this converter establishes reliable studio-to-venue links. It enables the transmission of uncompressed 1080P video with embedded audio over a single fiber for camera feeds and return video signals, supporting real-time broadcast operations up to 40 km.
Mission-Critical Security & Surveillance Systems: Ideal for modern IP-based security systems that integrate high-definition HD-SDI cameras. It facilitates long-haul video transport from remote cameras back to a central monitoring station while using minimal fiber infrastructure, making it cost-effective for city-wide surveillance, airport perimeters, and critical infrastructure protection.
Pro AV & Distributed Video Systems: Provides a robust backbone for professional audiovisual installations in corporate, education, and government settings. It is used in digital signage networks, distance learning studios, and command and control centers to distribute broadcast-level video and audio between locations, ensuring signal integrity and system stability.
Contribution and Distribution Feeds: Serves as an efficient solution for video contribution (sending feeds to a central point) and primary distribution (sending feeds from a central point) over fiber optic networks. Its ability to handle pathological patterns and its hot-swap capability ensure uninterrupted operation in 24/7 broadcast and media distribution environments.
