3G HD SDI Fiber Multiplexer with RS422 Audio Ethernet Tally Intercom Return Video
Model: LNK-MSDI Series
Product Description & Overview
The 3G/HD/SD-SDI, RS422, Audio, Ethernet, Tally, Intercom & Return Video over Fiber Multiplexer
represents a comprehensive signal integration solution for professional broadcast and live production
environments. This advanced fiber multiplexer supports simultaneous transmission of 3G-SDI, HD-SDI,
and SD-SDI video signals in compliance with SMPTE 424M-2006, 292, and 259 standards, while integrating
multiple auxiliary channels including RS422 camera control, bidirectional audio, 10/100Base-T Ethernet, tally
signals, intercom communication, and return video feed. The system efficiently consolidates all essential
broadcast signals onto a single multimode or single-mode fiber optic cable, significantly simplifying cable
infrastructure in complex production setups.
Engineered for multi-camera broadcast applications, this multiplexer establishes a complete signal pathway
between camera units and base station equipment. The forward channel transports pristine 3G/HD-SDI video
from camera to control room, while the return path delivers program video, genlock reference, intercom
communication, tally indicators, and Ethernet data back to the camera position. This bidirectional capability
enables full remote camera control and real-time communication between production crew and camera
operators, essential for live broadcasts and remote production scenarios.
The system's robust design ensures reliable operation in both studio environments and demanding field
production conditions. Utilizing either tactical fiber cables for mobile applications or SMPTE hybrid fiber
assemblies for fixed installations, this multiplexer provides complete immunity to electromagnetic interference
and ground loop issues. This makes it particularly suitable for outside broadcasts, sports events, news gathering,
and studio productions where signal integrity and operational reliability are paramount. By integrating multiple
signal types through a single fiber connection, the system dramatically reduces cable bulk and setup time while
maintaining the highest broadcast quality standards across all transmitted signals.
