1U Rack-Mountable 8-Channel SD/HD/3G-SDI Over Single Fiber CWDM Uncompressed Extender

1U Rack-Mountable 8-Channel SD/HD/3G-SDI over Single Fiber CWDM Uncompressed Extender

SDI Fiber Extender Overview:

The LNK-SDI-8V Series represents an advanced fiber optic transmission solution engineered for high-density broadcast and professional video applications. This 1U rack-mountable system incorporates CWDM (Coarse Wavelength Division Multiplexing) technology to simultaneously transmit eight independent SD/HD/3G-SDI video channels over a single optical fiber, maximizing bandwidth efficiency while minimizing infrastructure costs.

Our uncompressed fiber extenders maintain pristine broadcast-quality video signals throughout transmission, supporting full 1080P resolution with complete compliance to SMPTE standards (424M, 292M, 259M). Each channel features local loop-through monitoring outputs, enabling real-time signal verification without interrupting the primary transmission path. The integrated CWDM architecture provides exceptional wavelength stability and optical performance, ensuring reliable operation in demanding environments.

Beyond multi-channel video transmission, this comprehensive solution incorporates a dedicated reverse RS-485 data channel for bidirectional device control, supporting PTZ camera operations, robotic systems, and remote equipment management. The system delivers CD-quality audio transmission with perfect synchronization to video signals, meeting professional broadcast requirements for lip-sync accuracy and audio fidelity.

Specifically designed for broadcast facilities, live event production, and mission-critical video distribution networks, this rack-mountable extender provides complete electrical isolation and superior immunity to electromagnetic interference. The robust 1U chassis design offers space-efficient integration into standard equipment racks, making it an ideal solution for television studios, sports venues, and security operations centers requiring high-density SDI signal extension with uncompressed quality and reliable performance.
