E-link 1080P HD-SDI Fiber Converter LNK-HD-110 & LNK-3G-110 Series 3G/HD-SDI Fiber Converter supports 1-channel 3G/HD-SDI Video (audio embedded) & reversed RS422/485 data signal transmitted via fiber optical cable, and monitor the signal locally over a 3G/HD-SDI loop output. Overview The LNK-HD-110 & LNK-3G-110 Series represents a professional HD-SDI fiber converter transmission solution engineered for broadcast and professional video applications. This advanced fiber optic converter system delivers reliable 3G/HD-SDI video transmission with embedded audio and bidirectional data control over single-mode fiber infrastructure.This comprehensive HD-SDI fiber converter optic solution integrates complete signal transmission through a single fiber link. Each unit combines one channel of high-definition SDI video with embedded audio and reversed RS422/485 data connectivity for camera control and device management. The integrated 3G/HD-SDI loop output enables real-time local monitoring while maintaining uninterrupted primary signal transmission to the control room.The system operates as a matched pair of fiber optic transceivers, providing robust long-distance transmission while preserving original signal quality. Designed specifically for broadcast fiber applications, this professional video converter ensures uncompressed, low-latency transmission that meets rigorous broadcast standards. Its plug-and-play operation and rugged construction make it ideal for outside broadcasts, live event production, and fixed installation environments where signal reliability and quality are paramount. HD-SDI Fiber Converter Multi-Channel Audio Embedding Each video channel carries 8 embedded audio tracks, supporting synchronized audio-video transmission without separate cabling. HD-SDI Fiber Converter Automatic Signal Equalization Built-in cable equalization technology compensates for signal degradation, maintaining broadcast-quality integrity over extended copper runs. HD-SDI Fiber Converter Application ▶ Broadcast & Live Event ProductionDeployed in outside broadcast (OB) vans, sports stadiums, and concert venues, the converter ensures reliable 1080P HD-SDI signal transmission with embedded audio and bi-directional RS422/485 control.▶ Remote Camera & PTZ Control SystemsIdeal for surveillance networks and broadcast camera links, the device transmits uncompressed HD video and PTZ control signals over a single fiber. ▶ Industrial Monitoring & harsh Environment ApplicationsUsed in power substations, manufacturing facilities, and transportation hubs, the converter operates reliably within an extended temperature range (-40℃ to 85℃). ▶ Distance Learning & Corporate AV SystemsApplied in lecture halls, conference rooms, and multi-site training facilities, the device delivers high-definition video and audio over fiber, with loop-out monitoring for local display.
