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.
