4 Channel 3G-SDI Fiber Optic Converter Bidirectional Video Transmission 120km
4 Channel 3G-SDI Fiber Optic Converter Bidirectional Video Transmission 120km
Model: LNK-3GSDI-4BV Series
Product Description & Overview
The 4-Channel Bidirectional 3G-SDI Fiber Converter represents a cutting-edge solution for professional
broadcast and video transmission applications requiring high-density signal distribution. This advanced
fiber optic system enables simultaneous transmission of four channels of bidirectional 3G-SDI high-definition
video signals over a single optical fiber, maintaining full 1080p resolution and broadcast-standard video
quality throughout the transmission path. Each channel incorporates both local 3G/HD-SDI loop output
for signal monitoring and long-distance fiber optic transmission capability, providing comprehensive
signal management flexibility for live production environments.
Engineered to meet rigorous broadcast industry standards, this converter pair utilizes advanced wavelength
division multiplexing technology to consolidate multiple video channels alongside reverse RS-485 data
communication through a single fiber strand. The integrated RS-485 data channel supports bidirectional
control signals for PTZ camera operations, lens control systems, and other broadcast equipment requiring
reliable serial communication. The system delivers exceptional audio performance with CD-quality transmission
capabilities, ensuring perfect synchronization between video and audio components across extended distances.
This high-performance fiber converter finds ideal application in broadcast studios, live event production,
sports venues, and distance learning facilities where reliable multi-channel video transmission is critical.
The compact design and single-fiber implementation significantly reduces cabling complexity and infrastructure
costs while providing immunity to electromagnetic interference and ground loop problems common in traditional
copper-based video systems. With its robust construction and broadcast-grade components, this solution offers
television stations, production companies, and AV integrators a reliable and scalable platform for distributing high-
definition video content across campus environments, between buildings, or throughout large facilities while
maintaining the highest quality standards required for professional broadcasting applications.
