3G-SDI Fiber Extender with Analog Audio RS422 Ethernet Tally Sync 20km

Model: LNK-3G2V2BA2D1E1T1S

 Product Description & Overview

This advanced 3G-SDI Fiber Extender delivers comprehensive signal integration for professional

broadcast and surveillance applications, supporting bidirectional 3G-SDI video transmission combined

with multiple auxiliary signals through single-mode fiber infrastructure. The system incorporates a

complete signal management solution featuring 1-channel bidirectional 3G-SDI video, 2-channel

backward analog audio, bidirectional RS422 data communication, 100M Ethernet connectivity,

backward tally signaling, and backward analog tri-level sync transmission. The transmitter and

receiver pair operates seamlessly over single-mode optical cables, providing reliable long-distance

signal extension while maintaining broadcast-grade quality standards.

Engineered for superior performance in demanding environments, this fiber extender utilizes advanced

optical technology to ensure pristine video quality and real-time processing capabilities. The integrated

IP interface enhances system scalability and ensures compatibility with modern network infrastructure,

while the comprehensive signal support enables complete remote production control. The fiber optic

transmission technology provides complete immunity to electromagnetic interference, ground loops,

and radio frequency interference, significantly improving system reliability and signal security compared

to traditional coaxial cable systems.

The extender supports flexible transmission distances up to 20 kilometers with optional configurations

extending to 40km, 60km, or 80km ranges, making it suitable for large-scale installations and distributed

production environments. This solution is particularly valuable for live broadcasting applications, sports

venues, distance learning facilities, and high-definition surveillance systems requiring multi-signal transmission

over extended distances. By consolidating multiple signal types through a single fiber connection, the system

reduces cabling complexity while providing robust, interference-free connectivity that surpasses the limitations

of conventional coaxial-based systems, establishing new standards for signal integrity and operational reliability

in professional video transmission applications.
