SMB 3G-SDI Micro Extender 120km Auto-Sensing CWDM 18Ch SMPTE/DVB-ASI
Overview
The LNK-M3G-SMB1V-20 Series represents an advanced micro-sized fiber optic transmission solution engineered for space-constrained broadcast and professional video environments. This compact extender delivers robust transmission of 3G-SDI, HD-SDI, and SD-SDI high-definition digital video signals, along with DVB-ASI streaming capability, through either single-mode or multimode fiber infrastructure.
Supporting comprehensive industry standards including SMPTE 424M, 259M, 297M, 310M, and 305M (SDTI), this micro-extender ensures full compatibility with existing broadcast equipment and production workflows. The system incorporates sophisticated digital fiber optic transmission technology that eliminates the need for manual adjustments, enabling truly plug-and-play operation with simplified setup procedures.
Designed with power efficiency in mind, the extender operates on a single 5V power supply with optimized low power consumption, making it ideal for portable production setups and energy-conscious installations. The compact form factor allows for flexible deployment in broadcast trucks, fly-pack systems, and space-limited equipment racks where physical space is at a premium.
This micro-extender is particularly suitable for electronic news gathering, live event production, and mobile broadcasting applications where reliability, compact size, and ease of operation are essential. The robust construction ensures stable performance in demanding field conditions while maintaining broadcast-grade signal quality across all supported video formats.
