This product has been retired.

The Extron FOX 500 DVI Tx Fiber Optic Transmitter provides long haul transmission of DVI, audio, and RS-232 control signals over a single fiber. Engineered for reliability and exceptional high resolution image performance, it uses the Extron all-digital technology to deliver perfect pixel-for-pixel transmission of computer-video images up to UXGA 1600x1200 resolution, including HDTV 1080p/60. Designed specifically for AV systems, the transmitter includes many integrator-friendly features such as an EDID emulation mode, buffered input loop-through, RS-232 control, and real-time system monitoring.

The FOX 500 DVI Tx is part of the extensive FOX Series of fiber optic products from Extron and is compatible with FOX Series HDMI, DVI Plus, DVI, and VGA receivers. It can be used for simple point-to-point applications or in combination with FOX Series distribution amplifiers and matrix switchers to handle the most challenging AV system designs, from a simple conference room to an enterprise-wide fiber optic distribution system.

The transmitter is ideal for a wide range of applications requiring long distance transmission of high resolution content with the highest quality. Because transmission of content is inherently secure and immune to outside interference, fiber applications are favored in government, military, and medical environments. The FOX 500 DVI Tx features industry standard LC-type connectivity.

The FOX 500 DVI Tx is available in two versions, multimode and singlemode. The FOX 500 DVI Tx MM supports multimode fiber at 850 nm, which is typically used within buildings or facilities with moderate-range transmission distances. The FOX 500 DVI Tx SM supports singlemode as well as multimode fiber at 1310 nm. Singlemode fiber offers long-range transmission capability over extreme distances of up to 30 km (18.75 miles). It is used in very large facilities such as airports and stadiums, and for connecting over very long distances between facilities such as university campuses.

Offering convenient integration into AV systems, the FOX 500 DVI Tx transmitter accepts and digitizes unbalanced or balanced stereo audio and RS-232 control signals for transmission along with the DVI-D signals. It also includes a buffered input loop-through for viewing DVI video on a local monitor. EDID emulation ensures proper communication with the DVI source when no local monitor is present.

The FOX 500 DVI Tx and its corresponding receiver can be controlled and configured using the RS-232 port on the transmitter. With a second fiber link installed, functions for both units can be controlled at either location. Since the units are typically situated far apart, this capability adds considerable versatility, enabling adjustment and calibration of audio at the receiver. It also allows for verification of fiber link status between the units as well as the presence of DVI-D and audio input signals at the transmitter.

DVI-to-Analog RGB Conversion

The FOX 500 DVI Tx is ideal for AV systems that include a variety of digital and analog sources and displays. Pairing the transmitter with a FOX Series VGA receiver provides easy conversion of DVI-D signals to analog RGB.


Note: The FOX 500 DVI does not support transmission of DVI signals with HDCP - High-bandwidth Digital Content Protection.

FOX 500 DVI Tx
 NOTE     The FOX 500 DVI Tx is a transmitter with one or two fiber optic cables linking it to a receiver. It is available in singlemode or multimode version.
 NOTE     The analog audio signals are digitized in the transmitter, sent through the fiber cable, and converted back to analog audio in the receiver.
 NOTE     This transmitter is a class 1 laser product. It meets the safety regulations of IEC-60825.
Optical fiber interconnection between transmitter and receiver
   Number/type 1 or 2 fiber optic
    NOTE     Only one fiber is required to transmit video, audio, and unidirectional data. A second fiber is required to transmit return data for bidirectional control and communication.
   Connectors 2 LC connectors
   Operating distance
      Singlemode 30 km (18.75 miles) with singlemode (SM) cables with an SM unit
      Multimode 300 m (985') with 62.5 µm OM1 multimode (MM) cables with an MM unit
1 km (3280') with 50 µm OM2 multimode (MM) cables with an MM unit
2 km (6561') with 50 µm OM3/OM4 laser optimized multimode cable with an MM unit
    NOTE     Operating distance is approximate. These are typical maximum distances that may vary depending on factors such as fiber type, fiber bandwidth, connector splicing, losses, modal or chromatic dispersion, environmental factors, and kinks.
