Description

4-Ch Bi-Directional 3G-SDI Fiber Converter Broadcast-Grade up to 120Km

Overview

The LNK-3GSDI-4BV Series provides reliable 4-channel bidirectional 3G-SDI video transmission over

a single optical fiber, supporting broadcast-level uncompressed signals. With built-in auto equalization,

re-clocking, and reverse RS-485 data channel, it ensures pristine video quality up to 1080p60 over

distances from 10Km to 120Km. Designed for professional broadcasting, live production, and industrial

environments, its rugged rack-mount chassis and wide temperature tolerance deliver long-term stability

in demanding conditions.

Features

4-Ch Dual-Direction Video: Simultaneous bidirectional 3G-SDI signal transmission.

Auto Signal Recovery: Built-in cable equalization and re-clocking for stability.

Long-Range Fiber: Supports simplex LC fiber links up to 120Km.

Reverse Data Channel: Integrated RS-485 return path for camera control.

Uncompressed Quality: Full digital, broadcast-grade 3G-SDI with ultra-low BER.

Wide Format Support: PAL/NTSC, 720p, 1080i, and 1080p up to 60fps.

Industrial Build: 19” rack-mount aluminum housing with hot-swap design.

Extreme Durability: Operates from -40°C to +85°C with high MTBF (>100,000h).
