1080P Bi-directional HD-SDI Fiber Converter Hot-Swap & 40km over Single Fiber1080P 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 groundbreakingBi-directional HD-SDI Fiber Converter. Unlike conventional solutions that require separate fibers for send and receive paths, our innovative technology transmits and receivesfull 1080P HD-SDI video with 4-channel embedded audioover a single fiber strand. This revolutionaryBi-directional HD-SDIdesign not only reduces fiber core consumption by 50% but also dramatically simplifies cable management in crowded conduits and patch panels. Ideal forbroadcast 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 stunninglong-distance transmission up to 40 kilometerswithout any signal degradation, making it perfect for connecting remote camera locations instadiums, campuses, or city-wide surveillance networks. Advancedautomatic cable equalization and reclockingtechnologies continuously clean and strengthen the signal, ensuring broadcast-quality integrity from end to end. Built with anultra-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.
