Product Description & Overview
The 1U Rack-Mountable 8-Channel SD/HD/3G-SDI over Single Fiber CWDM Uncompressed Extender
delivers a high-density professional video transmission solution for broadcast and live production environments.
This advanced fiber optic extender utilizes CWDM (Coarse Wavelength Division Multiplexing) technology to
simultaneously transmit eight channels of SD/HD/3G-SDI video signals through a single optical fiber while
maintaining uncompressed broadcast-quality video standards. The system includes matched transmitter
and receiver units that support full 1080p resolution with integrated local loop-through outputs for real-time
signal monitoring at both transmission and reception points.
Engineered for broadcast infrastructure applications, this extender maintains complete signal integrity
through uncompressed digital transmission, ensuring zero latency and perfect synchronization across
all eight video channels. The integrated reverse RS-485 data channel enables bidirectional communication
for camera control, tally signals, and equipment management, while the CD-quality audio transmission
preserves pristine audio-video synchronization. The 1U rack-mountable form factor optimizes space
efficiency in broadcast racks, mobile production trucks, and equipment rooms, providing maximum
channel density per rack unit.
This high-performance extender finds ideal application in television broadcast centers, live event production,
sports broadcasting, and large-scale AV distribution systems where reliable multi-channel video transport is
essential. The single-fiber CWDM implementation significantly reduces fiber infrastructure costs and simplifies
cable management while providing complete immunity to RF interference, ground loops, and signal degradation.
With its robust construction and broadcast-grade components, this solution offers broadcasters and AV professionals
a reliable, scalable platform for distributing multiple high-definition video feeds between control rooms, across
campuses, or throughout large venues while meeting the stringent quality requirements of professional
broadcast operations.
