Frequently Asked Questions - AVX-DVI-FO-SP4 Black Box

What is the maximum distance supported by the AVX-DVI-FO-SP4?

When used with single-mode fiber, the AVX-DVI-FO-SP4 can extend DVI and audio up to 1.5 km (4921 ft). With multimode fiber, the distance is limited to 500 m (1640 ft).

Does the AVX-DVI-FO-SP4 require external power?

No, the AVX-DVI-FO-SP4 is a passive splitter and does not need any external power. Power is only required for the transmitter and receiver modules.

How many displays can I connect using this splitter?

The AVX-DVI-FO-SP4 has 4 output ports, so you can connect up to 4 displays. By cascading multiple splitters, you can distribute to up to 32 displays.

What type of fiber optic cable should I use?

You can use either single-mode (9/125 µm) or multimode (50/125 µm or 62.5/125 µm) fiber. Single-mode is recommended for longer distances.

What resolutions and video formats are supported?

The system supports DVI-D video up to WUXGA (1920 x 1200) with 24-bit color depth. It complies with DVI 1.0 standards.

Does this splitter transmit audio as well?

Yes, the AVX-DVI-FO-SP4 transmits stereo audio along with the DVI video over a single strand of fiber. Audio must be connected separately at the transmitter and receiver.

What is the optical loss introduced by the splitter?

The AVX-DVI-FO-SP4 introduces an optical loss of 6 dB. This must be accounted for when calculating the total link budget.

How do I install the AVX-DVI-FO-SP4?

Connect the fiber input from the transmitter to the interconnect LC port. Then connect each of the four output LC ports to the receivers (or downstream splitters). No power is needed. Ensure all connectors are clean.

What should I do if there is no image on the display?

Check that the transmitter and receiver are powered on, the fiber cables are connected properly, and the display is set to the correct input. The LED on the transmitter should show violet if a video signal is present. Also verify the resolution does not exceed 1920x1200.

What is included in the box with the AVX-DVI-FO-SP4?

The package contains only the 4-Port Fiber Splitter unit. No power supply, cables, or other accessories are included. You will need separate transmitter/receiver kits and fiber cables.

2. Overview

2.1 Introduction

The DVI Extender transmits high-quality video signal formats and audio to a remote screen, without compromising the original media quality. The DVI Extender delivers a full HD resolution signal through one fiber optic cable up to 1.5 kilometers. It's an ideal solution for systems where high-resolution and high-quality video signals need to be displayed over long distances.

Connect the extender in a point-to-point configuration to transmit high-resolution video to a remote display. The transmitter module is compatible with all kinds of display devices. It reads and stores the display's EDID information to prevent EDID handshake problems. Installing the extender is easy and more flexible than ever.

Connect the extender in a point-to-multipoint configuration to distribute high-resolution video to up to 32 displays. Use the 2-, 4-, and 8-port splitters to achieve flawless video distribution and extension. All splitters are passive devices and do not require external power.

Typical applications include public informational displays in elevators, trains, subways, airports, shopping malls, museums, or hotels.

2.2 Features

• Delivers high-quality multimedia content in real time from a media player to a distant screen while maintaining crystal-clear video. A high-definition video signal from a single player to a display can be extended up to 1.5 km without electrical support for splitters. The DVI Extender increases the range of the display network and enables you to set up your screens at any locations without sacrificing the quality of media.
• Supports audio extension. The DVI Extender transmits both audio and video over a single-strand fiber optic cable.
• Extends all DVI VESA standards all the way up to a 1920 x 1200 resolution.
• Offers programmable EDID. The transmitter reads and stores the display's EDID information and provides a handshaking capability for any type of display with different resolutions.
• Consumes very little power. Transmitters and receivers consume 3 W or less for transmitting and receiving Full HD resolution video signals and CD-quality audio.
• Split, extend, and distribute DVI video and stereo audio using the passive fiber splitters.

The DVI Extender is the best system to use when extending high-quality DVI video and stereo audio over long distances. The extender includes a transmitter module and a receiver module.

The transmitter module encodes the audio/video signals into an optical signal and the receiver module decodes the optical signal back into the original audio/video signal.

In point-to-point transmission, each display needs a transmitter and a receiver to extend the source.

3. Installation

3.1 Connections

Connect the transmitter module to the DVI port on the PC/video card and connect the receiver module to the DVI port on the digital display device.

Use the DVI Extender with an LC fiber optic cable (single-mode optical fiber: 9/125 μm).

3.2 EDID Setting

The transmitter has a basic EDID table built in that includes the most commonly used display modes. If you encounter problems selecting the right resolution and would like to copy the EDID table from your monitor, follow these instructions:

- Connect the transmitter to the DVI port on the monitor.

Figure 3-1. DVI-D connector on the monitor.

Figure 3-2. Transmitter plugged into remote monitor.

- Connect the DC power to the transmitter and power on the monitor.

4. Troubleshooting

4.1 Problems/Solutions

Problem: No image

Solutions:

1. Make sure the PC power is on.
2. Check whether the computer and the monitor are properly connected.
3. Turn the PC power on and off.
4. Make sure the fiber cable between the transmitter and the receiver is properly connected.
5. Check whether the LED on the transmitter shows a violet light. If the LED does not show any activity, the video settings on the PC may be incorrect.
6. Make sure the LED on the receiver shows a violet light. If the LED does not show any activity, the signal from the fiber cable is missing. Check the cable connections.

Problem: Screen artifacts appear.

Solution: Check the resolution of the DVI source. This device supports up to a 1920 x 1200 WUXGA resolution.

Problem: No sound

Solutions:

1. Make sure the power is on for the audio source.
2. Check whether the speaker power is on.
3. Make sure the audio cable is correctly connected.
