RB-12GSDI-485 12G SDI over SM/MM fiber extender single strand, SMPTE 2082 (2160p@60Hz UHD), RS-485 data, SET of TWO
Overview
The RB-12GSDI-485 is a digital fiber optic transmission system designed to transport a single 12G SDI video signal alongside an RS-485 data channel. The system supports UHDTV 4K resolutions up to 2160p at 60Hz. Utilizing a single-strand fiber connection, it provides signal extension for both single-mode (up to 10km) and multi-mode (up to 500m) fiber architectures. The units are designed for plug-and-play operation, requiring no manual configuration.
Key Features
- Supports SMPTE ST-2082 standard, allowing for transmission of 12G-SDI, 6G-SDI, 3G-SDI, HD-SDI, and SD-SDI signals to ensure compatibility with varied broadcast video equipment.
- Includes a 2-wire RS-485 data channel to facilitate bi-directional control or auxiliary data communication over the same fiber strand.
- Features integrated clock recovery and signal re-shaping circuitry to maintain digital signal integrity over long distances.
- Built to an industrial temperature grade specification (-20 to +75 Celsius), allowing for operation in environments with fluctuating thermal conditions.
- Provides dedicated LED status indicators for power, fiber link, data activity, and SDI signal presence, enabling immediate visual verification of operational status.
