Mini 4K DVI Fiber Extender with RS232 Control 80km Range Uncompressed 4K@60Hz Video
Product Overview
The LNK-MDR4K Series Mini 4K DVI Fiber Optic Extender with RS232 delivers professional-grade long-distance transmission of ultra-high-definition video and bidirectional control signals over a single fiber optic cable. This advanced extender supports resolutions up to 4Kx2K@60Hz (YUV 4:2:0), ensuring exceptional image quality for demanding display applications.
Engineered with robust fiber optic technology, the system converts DVI video and RS232 serial data into a high-speed 10Gb/s optical signal, enabling reliable transmission over distances extending to 80km. This fully optical pathway provides complete immunity to electromagnetic interference (EMI) and radio frequency interference (RFI), guaranteeing signal integrity in electrically noisy environments.
The extender maintains compliance with international RoHS standards and employs lead-free manufacturing processes, meeting stringent environmental requirements for global markets. Its compact, miniaturized design facilitates flexible integration into space-constrained installations while maintaining industrial-grade performance.
Ideal for large-scale digital signage, professional conferencing systems, broadcast environments, and high-end home theater applications, the LNK-MDR4K Series provides a comprehensive solution for integrated AV systems requiring simultaneous high-resolution video extension and remote device control with maximum operational stability.
Key Features
High-Speed Uncompressed Transmission
Delivers uncompressed video transmission with zero latency and no signal loss, maintaining pristine image quality through a high 10.2 Gbps data rate for real-time visual applications.
Extended Protocol Compatibility
Supports DVI 1.0 and HDCP 1.2 protocols, ensuring broad compatibility with a wide range of source equipment and enabling the transmission of protected content.
Ultra-Long Distance & Environmental Resilience
Achieves point-to-point transmission over exceptional distances up to 80km via single-mode fiber, with a wide operating temperature range (-10°C to 50°C) for stable performance in varied climates.
Intelligent System Integration
Features Auto EDID management for automatic configuration with various displays, and supports bidirectional RS232 serial signals for remote device control (e.g., matrix switchers, projection screens) over the same fiber link.
Robust & User-Friendly Design
Engineered with a hot-pluggable interface for safe, flexible system maintenance and offers superior EMI/RFI noise immunity in electrically noisy settings. The miniature form factor ensures easy, space-saving installation in rack-mounted and compact environments.
