Gefen

Gefen delivers innovative, progressive computer and electronics add-on solutions that harness integration, extension, distribution and conversion technologies. Gefen's reliable, plug-and-play products supplement cross-platform computer systems, professional audio/video environments and HDTV systems of all sizes with hard-working solutions that are easy to implement and simple to operate.

The Gefen 3GSDI Fiber Optic Extender

The Gefen 3GSDI Fiber Optic Extender is a miniature digital video data transport system over fiber optic cable supporting 1080p for 3G-SDI and HD-SDI. It converts a one-channel SMPTE-424M 3G-SDI, SMPTE-292M HD, or SMPTE-259M serial digital video signal over extended distances up to 12 miles (20 km) over either single-mode or multi-mode fiber optic cable.

How It Works

The Sender receives the SDI input signal and converts the SMPTE-424M / 292M / 259M SDI signals to optical data. The Receiver unit collects the optical data from the fi ber cable and converts it to an SDI signal.

READ THESE NOTES BEFORE INSTALLING OR OPERATING THE 3GSDI FIBER OPTIC EXTENDER

- The use of an intermediate cable or adapter is not recommended. Additional coupling devices may deteriorate the signal transmission.

Features

• Extends 3G-SDI up to 12 miles (20km)
  • Transports Multi-rate HD-SDI Digital Video over a single ST fiber cable.
• Supports SMPTE-424M (3G-SDI), SMPTE-292M (HD-SDI), or SMPTE-259M (SDI) specifications.
  • Automatic Input Equalization
• Latch-Locking Power Connector
  • HD-SDI BNC input connector and ST terminated fiber optical connector
• Robust metal die-casting enclosure for harsh environments
