The DDL TX/RX optical DVI extender kit provides a transmitter and receiver pair designed to extend DVI video signals over multimode fiber - supporting TMDS digital transmission to remote flat panel displays. The system separates RGB and clock channels across four optical lanes to preserve signal integrity over long distances. It is intended for AV and broadcast environments where cable runs exceed the reach of copper DVI.

Key features include a 4-channel LC multimode optical link using 850 nm VCSELs on the transmitter and GaAs PIN photodiodes on the receiver - delivering 1.65Gbps per channel. The kit supports WUXGA (1920 x 1200) and 1080p (1920 x 1080) resolutions and performs EDID self-detection for source/display handshake. EMC and safety approvals include CE, UL and FCC to meet regulatory requirements.

Performance characteristics are driven by TMDS DVI 1.0 signaling and a per-channel video bandwidth of 1.65Gbps. Module dimensions are compact at 39.5 x 15.0 x 70.0 mm and each module weighs 45g. Recommended fiber is 50/125 nm multimode glass-fiber to maintain specified link performance and distance.

Connectivity options include a 24-pin DVI-D plug on both transmitter and receiver and a 1x4 LC optical connector for the fiber link. The transmitter uses a 4-channel LC multimode optical output while the receiver uses a 4-channel GaAs PIN photodiode optical input. The unit maintains TMDS signal integrity end-to-end and supports standard DVI displays and graphics sources that comply with DVI 1.0.

Typical applications include digital signage installations where displays are located hundreds of meters from the source, AV systems in corporate and education facilities requiring clean long-distance links, and broadcast or control room scenarios that demand reliable TMDS extension. The separate transmission of R G B and clock channels reduces crosstalk and preserves video timing for critical displays. The EDID auto-detect simplifies integration with mixed vendor equipment.

Installation is straightforward using standard LC multimode fiber and a 24-pin DVI-D connection - no complex configuration is required beyond cable routing and EDID negotiation. The compact modules are suitable for rack or enclosure use and are built to meet industry EMC and safety standards. Overall the DDL TX/RX kit delivers a simple optical solution for extending DVI video with predictable performance.
