4K 12G-SDI Fiber Converter with Tally RS485 20kmE-link 12G-SDI Fiber Converter
LNK-M12G-1V1T1D Series Mini-type 12G-SDIFiber Converter supports 1Ch 12G Video(audio embedded), 1Ch Tally signal and 1Ch Backward RS485transmitted 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-edge4K 12G-SDI fiber convertersolution, engineered to meet the demanding requirements of modern broadcast and professional video transmission. This advancedfiber optic transmission systemdelivers exceptional performance for4K UHD contentwhile maintaining full backward compatibility with existing HD-SDI infrastructure.
This sophisticated12G-SDI fiber converterintegrates multiple signal types through a single fiber connection, combining one channel of4K 12G-SDI videowith embedded audio, onetally signalfor camera status indication, and one channel ofbi-directional RS485 datafor comprehensive device control. The integrated12G-SDI loop-through outputenables real-time local monitoring while maintaining uninterrupted primary signal transmission to the control room or production facility.
Designed as a compactmini-type fiber converter, the system operates through matched transmitter and receiver units, providing reliablelong-distance transmissionwhile preserving original signal quality. The device supports comprehensive video formats including4K UHD (3840×2160@60Hz), 1080p, 1080i, and 720p resolutions, making it suitable for both current4K production workflowsand legacy HD systems.
Thisprofessional 4K fiber converteris 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 onbroadcast-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.
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.
