The GefenPRO 3GSDI Fiber Optic Extender is a miniature serial digital video data transport system extending video over fiber optic cable supporting 1080p for 3G-SDI. It converts a one-channel SMPTE-424M (3G-SDI), SMPTE-292M (HD-SDI), SMPTE-259M (SDI), or DVB-ASI serial digital video signal over extended distanes up to 18 miles (30 kilometers) using single-mode or up to 1640 feet (500 meters) using multimode fiber optic cable, terminated in ST connectors.

 The Sender unit receives the SDI input signal from a compatible SD/HD/3G SDI source and converts the SMPTE-424M / 292M / 259M SDI signals to optical data. The Receiver unit converts the data to an SD/HD/3G SDI signal, which in turn connects to BNC connection point, or a display. Both Sender and Receiver units are powered by an external 5V locking power supply.
Note: The GEF-3GSDI-FO-141 differs from the EXT-3GSDI-FO-141 in that it adds a re-clocking feature.



Gefen GEF-3GSDI-FO-141 Features:

  • Extends 3G-SDI up to 12 miles (20km)
  • Transports Multi-rate HD-SDI Digital Video over 1 Fiber
  • Supports SMPTE-424M (3G-SDI), SMPTE-292M (HD-SDI), or SMPTE-259M (SDI) specifications.
  • Automatic Input Equalization
  • Output Clock Recovery
  • Latch-Locking Power Connector
  • 3G-SDI BNC input connector and ST terminated fiber optical connector
  • Robust metal die-casting enclosure for harsh environments

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 fiber cable and converts it to an SDI signal.
