INTRODUCTION

Congratulations on your purchase of the 3GSDI Fiber Optic Extender. Your complete satisfaction is very important to us.

GefenPRO

In the realm of video distribution, certain features are invaluable in a commercial or broadcast environment. Accommodations such as a build-inpower supply and flat blackrack-mountenclosures set GefenPRO apart from our traditional products. Complex distribution units allow for professional DVI,3G-SDI,and HDMI signals to be routed and converted easily and seamlessly, while being backed up by a renowned and dependable technical support team. Gefen invites you to explore the GefenPRO product line and hopes that you find the solution that fits your needs.

The GefenPRO 3GSDI Fiber Optic Extender

The GefenPRO 3GSDI Fiber Optic Extender is a miniature digital video data transport system over fiber optic cable supporting 1080p for 3G-SDIand HDSDI. It converts aone-channelSMPTE-424M3G-SDI,SMPTE-292MHD, orSMPTE-259Mserial digital video signal over extended distances up to 19 miles (30 kilometers).

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.

OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 3GSDI FIBER OPTIC EXTENDER

The GefenPRO 3GSDI Fiber Optic Extender will connect two 3G-SDIdevices using anST-terminatedfiber cable to a distance of up to 12 miles (20 kilometers.).HD-SDIcan be extended up to 19 miles (30 kilometers). The input has automatic equalization and the output is automatically reclocked.

3G-SDIcan be extended up to 1640 feet (500 meters) when using multimode fiber.

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

TROUBLESHOOTING

No picture / display shows a blank screen

Ensure that all jacks that are used by the 5 V DC power supplies are firmly connected.

Ensure that the SDI connector is firmly plugged in to the SDI source and SDI display. Ensure that the Sender and Receiver module parts are connected to the SDI source and SDI display, respectively.

Check if the SDI source and SDI display are powered on and properly booted.

Reset the system by unplugging and reconnecting the Sender SDI module or Receiver SDI module. Re-bootthe system while connecting the3G-SDIFiber Optic Extender.

Verify that the fiber cables are not damaged.

Picture is distorted or contains noise

Verify the quality of the SDI source and check the length of the fiber cable. The 3GSDI Fiber Optic Extender will extend 3G-SDIup to a distance of 12 miles (20 kilometers) usingsingle-modefiber.HD-SDIcan be extended up to a distance of 19 miles (30 kilometers) usingsingle-modefiber.3G-SDIcan be extended to a maximum of 1640 feet (500 meters) usingmulti-modefiber.
