E-link 12G-SDI Fiber Converter LNK-M12G-1V1T1D Series Mini-type 12G-SDI Fiber Converter supports 1Ch 12G Video (audio embedded), 1Ch Tally signal and 1Ch Backward RS485 transmitted via fiber optical cable, and monitor the signal locally over a 12G loop output. 4K 12G-SDI Fiber Converter Overview The LNK-M12G-1V1T1D Series represents a cutting-edge 4K 12G-SDI fiber converter solution, engineered to meet the demanding requirements of modern broadcast and professional video transmission. This advanced fiber optic transmission system delivers exceptional performance for 4K UHD content while maintaining full backward compatibility with existing HD-SDI infrastructure.This sophisticated 12G-SDI fiber converter integrates multiple signal types through a single fiber connection, combining one channel of 4K 12G-SDI video with embedded audio, one tally signal for camera status indication, and one channel of bi-directional RS485 data for comprehensive device control. The integrated 12G-SDI loop-through output enables real-time local monitoring while maintaining uninterrupted primary signal transmission to the control room or production facility.Designed as a compact mini-type fiber converter, the system operates through matched transmitter and receiver units, providing reliable long-distance transmission while preserving original signal quality. The device supports comprehensive video formats including 4K UHD (3840×2160@60Hz), 1080p, 1080i, and 720p resolutions, making it suitable for both current 4K production workflows and legacy HD systems.This professional 4K fiber converter is particularly valuable for space-constrained environments such as outside broadcast vehicles, mobile production units, and compact equipment racks, where its miniature form factor doesn’t compromise on broadcast-grade performance. The unit’s robust construction and plug-and-play operation ensure quick deployment in temporary field production setups and permanent installation scenarios alike. 4K 12G-SDI Fiber Converter Multi-Channel Audio Embedding Capability Each 12G-SDI interface carries 8 channels of embedded digital audio, enabling synchronized audio-video transmission without separate audio cabling infrastructure. 4K 12G-SDI Fiber Converter Advanced Signal Integrity Protection Built-in automatic cable equalization technology compensates for signal degradation in long copper runs, maintaining pristine signal quality throughout the transmission path. 4K 12G-SDI Fiber Converter Application ▶ Outside Broadcast & Live Event ProductionDeployed in OB vans, sports arenas, and concert broadcasts, the converter ensures low-latency transmission of 12G-SDI video with real-time tally control and PTZ camera management.▶ Broadcast Studio & Remote Production SystemsUsed for camera-to-control room links, the device delivers uncompressed 4K video with SMPTE-compliant signal integrity. ▶ Large-Venue AV & Corporate BroadcastingIdeal for conference centers and distance learning facilities, the system transmits multi-channel audio-embedded video with RS485 serial control for AV device management.
