1080P 3G-SDI SMB 3G-SDI/HD-SDI/SD-SDI Fiber Converter Broadcast & LiveE-link 3G-SDI SMB Fiber Converter
LNK-M3G-SMB1V-20 Series 3G-SDI/HD-SDI/SD-SDI micro extender fiber optic transmission system that transmits one 3G-SDI, HD-SDI, SD-SDI high definition digital video or one DVB-ASI stream through one single mode or multimode fiber supporting SMPTE424M, SMPTE259M, SMPTE297M, SMPTE310M, SMPTE305M (SDTI) standards.
Overview
The LNK-M3G-SMB1V-20 Series represents a compact3G-SDI SMB fiber convertersolution designed for professional broadcast and video transmission applications. This advancedfiber optic transmission systemdelivers reliable performance for3G-SDI/HD-SDI/SD-SDIsignals while maintaining fullDVB-ASIcompatibility through both single-mode and multimode fiber infrastructure.
Engineered with plug-and-play operation, thismicro fiber extenderrequires zero manual adjustments while supporting comprehensiveSMPTE standards complianceincluding SMPTE-424M, SMPTE-259M, and SMPTE-297M specifications. The device incorporatesadvanced digital processing technologythat automatically optimizes signal parameters for pristine video quality across extended distances.
As a compactSMB coaxial fiber converter, the system features a space-efficient form factor with low-power 5V operation, making it ideal for power-sensitive installations and mobile production environments. The unit’sfiber optic transmission technologyensures broadcast-grade signal integrity without compression artifacts or latency issues.
This versatile3G-SDI to fiber converterserves multiple applications including broadcast studios, live event production, remote camera feeds, and digital signage networks. Its robust construction and simplified installation process make it particularly suitable for temporary field production setups and permanent infrastructure deployments where reliability and quick deployment are critical requirements.
Automatic Multi-Standard Signal Detection
Provides intelligent signal recognition for 3G-SDI/HD-SDI/SD-SDI formats without requiring manual configuration or switching.
Extended-Range Fiber Optic Transmission
Delivers reliable signal transport up to 120km over single-mode fiber, supporting long-distance broadcast and production applications.
Application
▶ Outside Broadcast & Live Sports Production
The CWDM-ready designallows integration intowavelength division multiplexing networks, enabling multiple camera feeds over one fiber.
▶ Broadcast Studio & Remote Camera Links
Used forcamera-to-control room connectivity, the system supportsSMPTE-compliant signal transport(3G/HD/SD-SDI) andDVB-ASI streams without manual configuration.
▶ Traffic Management & Surveillance Systems
Applied in intelligent transportation systems (ITS) and security monitoring networks.
▶ Telecommunications & Content Distribution
With support for long-haul optical transport and CWDM multiplexing, the unit fits seamlessly into metro video networks and contribution links.
