Product Datasheet

The Extron FOX USB Extender is a fiber optic transmitter and receiver set for long haul transmission of USB signals over fiber optic cabling. Engineered for reliability and exceptional performance, it uses Extron all-digital technology to deliver perfect transmission of USB 2.0, 1.1, and 1.0 signals with data transfer rates up to 480 Mbps. Designed specifically for AV systems, the FOX USB Extender includes many integrator friendly features such as peripheral emulation, an active four-port hub that supplies 5 Volts, 500 mA per port, and real-time system monitoring. Compact, low profile enclosures allow for discreet installation.

As part of the extensive FOX Series of fiber optic products from Extron, the FOX USB Extender can be used for simple point-to-point applications or in combination with FOX Series matrix switchers for support of enterprise-wide installations. Used in conjunction with an Extron FOX Series DisplayPort, HDMI, DVI, or VGA extender, the FOX USB Extender is capable of transmitting Keyboard-Video-Mouse - KVM signals very long distances over a fiber optic infrastructure.

The FOX USB Extender enables direct connection of USB peripherals to a host computer at extreme distances, eliminating the need for additional IP network drops, equipment, software, or drivers. This simplifies integration in KVM applications by avoiding IT-specific design criteria that may be in conflict with the needs of KVM in professional AV installations.

The transmitter features peripheral emulation to support uninterrupted communication between the host and the USB device, ensuring USB port recognition during system boot-up and in a switching environment. For simplified integration, the receiver features an active four-port hub that supplies 5 Volts, 500 mA per port to power attached devices. Also, port LED indicators provide visual confirmation of system activity.

The extender is ideal for a wide range of applications requiring long haul transmission of USB 2.0, 1.1, and 1.0 compliant signals with data rates up to 480 Mbps. Peripheral emulation ensures reliable communication, even without a tie being made to a connected device. In addition, fiber optic transmission of content is inherently secure and immune to outside interference.

The FOX USB Extender features industry standard LC-type connectivity and is available in two formats: multimode and singlemode. The FOX USB Extender MM supports multimode fiber at 850 nm, which is typically used within buildings, between floors, or at facilities with moderate-range transmission distances. The FOX USB Extender SM supports singlemode fiber at 1310 nm, offering long-range USB 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 long distances between facilities such as at a university campus or medical complex.
