The Extron FOX3 T 201 Fiber Optic Transmitter provides long haul transmission of HDCP-compliant HDMI video, audio, RS-232 control, and IR control over fiber optic cabling. Engineered for exceptional high-resolution image performance, the transmitter uses Extron all‑digital technology to deliver perfect pixel-for-pixel, uncompressed transmission of images up to 4K/60 @ 4:4:4 over two fibers or mathematically lossless 4K/60 @ 4:4:4 over one fiber. Designed specifically for AV systems, the FOX3 T 201 also includes many integrator-friendly features such as Key Minder®, EDID Minder®, audio embedding, Ethernet monitoring and control, audio gain and attenuation, and real-time system monitoring. A compact, low profile enclosure allows for discreet installation.

Uncompromised Image Quality

Supporting data rates up to 18 Gbps, the FOX3 T 201 is designed to extend uncompressed video images up to 4096x2160 at 60 Hz with 4:4:4 chroma sampling over two fibers or mathematically lossless video images over one fiber, making it ideal for mission-critical applications or any environment that requires the transmission of very high-resolution imagery. Maintaining a 60 Hz frame rate with a 4:4:4 color space provides smooth frame transitions in full-motion video and ensures the details of high-quality computer images, such as CAD drawings, are preserved.

Engineered to Streamline Integration

The FOX3 T 201 Transmitter can be used with a FOX3 SR 201 Receiver in point‑to‑point applications or in combination with a FOX3 Series matrix switcher for an enterprise‑wide HDCP‑compliant distribution system of 4K/60 4:4:4 HDMI video, audio, RS‑232 control, and IR control signals.

To simplify integration with digital sources and displays, the FOX3 T 201 features two Extron technologies: EDID Minder and Key Minder. EDID Minder automatically manages EDID by maintaining continuous EDID communication between connected devices, ensuring that the source powers up properly and maintains optimal video output for display. Key Minder authenticates and maintains continuous HDCP encryption to support quick and reliable switching in professional AV environments while enabling simultaneous distribution of a single source signal to one or more displays. In addition, an input loop-through allows an output signal to drive a local monitor that also supports 4K/60 video, and the built-in internal test patterns present display alignment patterns aiding in setup and configuration.

Control Signal Extension and Device Management

The FOX3 T 201 offers convenient local and remote system access for configuration, operation, and monitoring. The front panel USB configuration port enables system configuration without having to access the rear panel. The direct RS-232 and IR insertion ports extend control signals to remote devices over the fiber optic cable. Sources and displays can be controlled from either the transmitter or receiver end using either RS‑232 or IR signals. When used with a FOX3 Series matrix switcher, the remote RS-232 port can receive inserted control data from the matrix switcher over the fiber optic cable for control of the connected device. The transmitter also features a LAN port, enabling the FOX3 T 201 to be proactively monitored and managed over the network using standard TCP/IP protocols.

Multimode and Singlemode Models for Design Flexibility

The FOX3 T 201 is available in multimode and singlemode models. The FOX3 T 201 MM model supports multimode fiber at 850 nm, which is typically used within buildings or facilities with moderate‑range transmission distances. The FOX3 T 201 SM supports singlemode at 1310 nm, offering long‑range transmission capability over extreme distances. It can be used in very large facilities such as airports and stadiums, and for connecting over very long distances between facilities such as university campuses. Because transmission of content is inherently secure and immune to outside interference, fiber applications are particularly favored in government, military, and medical environments. The transmitter features industry-standard LC‑type connectivity. The 1" (2.5 cm) high, half-rack width metal enclosure is designed for discreet installation in professional AV environments.
