FOXBOX Tx VGA/YUV MM Multimode - Transmitter 60-1058-11
FOXBOX Tx VGA/YUV SM Singlemode - Transmitter 60-1058-12 Retired

The Extron FOXBOX Tx VGA/YUV Fiber Optic Transmitter provides long haul transmission of high resolution VGA or HD component video, audio, and RS-232 control signals over a single fiber. Engineered for reliability and exceptional high resolution image performance, it uses Extron all-digital technology to deliver perfect pixel-for-pixel transmission of computer-video images up to UXGA 1600x1200 resolution and HDTV up to 1080p/60. Designed specifically for AV systems, the FOXBOX Tx VGA/YUV includes many integrator-friendly features such as audio gain and attenuation, RS-232 control, and real-time system monitoring. A compact, low profile enclosure allows for discreet installation.

The FOXBOX Tx VGA/YUV is part of the extensive FOX Series of fiber optic products from Extron and is compatible with the 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 FOXBOX Tx VGA/YUV 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 transmitter features industry standard LC-type connectivity.

The FOXBOX Tx VGA/YUV is available in two versions, multimode and singlemode. FOXBOX Tx VGA/YUV MM supports multimode fiber at 850 nm, which is typically used within buildings or facilities with moderate-range transmission distances. The FOXBOX Tx VGA/YUV 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, as well as connecting over very long distances between facilities such as university campuses.

The FOXBOX Tx VGA/YUV accepts, digitizes, and transmits RGBHV/RGBS or HD component video, along with unbalanced stereo audio and RS-232 control signals. It also provides controls for optimizing audio signals.

The FOXBOX Tx VGA/YUV transmitter 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 video and audio at the receiver. It also allows for verification of fiber link status between the units as well as the presence of video and audio input signals at the transmitter.

Analog RGB/HDTV-to-Digital Conversion

The FOXBOX Tx VGA/YUV is ideal for AV systems that include a variety of digital and analog displays and sources. Pairing the FOXBOX Tx VGA/YUV with a FOX Series HDMI, DVI Plus or DVI receiver provides easy conversion of analog RGB or HD component to HDMI/DVI-D.

 NOTE     The analog RGB input signal is digitized pixel for pixel in the transmitter, sent digitally through the fiber cable, and converted back to analog RGB in the receiver.
 NOTE     The analog audio signal(s) is (are) digitized in the transmitter, sent through the fiber cable, and converted back to analog audio in the receiver.
 NOTE     These transceivers are class 1 laser products. They meet the safety regulations of IEC-60825.
