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
Extended Protocol Compatibility
Ultra-Long Distance & Environmental Resilience
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.
