Product Description
The Extron FOX3 T 301 MM (P/N 60-1522-11) is a multimode fiber optic transmitter that provides long-haul transmission of HDCP-compliant HDMI video, USB, audio, RS-232 and IR control, and 3D sync signals over fiber optic cable. Using Extron all-digital technology, this FOX3 T 301 fiber optic transmitter delivers pixel-for-pixel uncompressed video up to 4K/60 at 4:4:4 chroma sampling over two fibers, or mathematically lossless 4K/60 at 4:4:4 over a single fiber. It is engineered for AV and KVM systems that require exceptional high-resolution image performance.
This multimode HDMI fiber optic extender transmitter supports HDMI 2.0 data rates up to 18 Gbps and integrates Extron EDID Minder and Key Minder to streamline integration with sources and displays. A buffered HDMI input loop-through drives a local 4K/60 monitor, while integrated USB signal extension carries USB 3.0, 2.0, 1.1, 1.0, and HID peripherals over the same fiber as video and audio, eliminating the need for separate USB extenders in keyboard, video, and mouse deployments. For point-to-point links, pair this transmitter with the Extron FOX3 SR 301 MM scaling receiver, or combine it with a FOX3 Series matrix switcher for enterprise-wide signal distribution.
The 850 nm multimode model supports moderate-range runs within buildings and campuses up to 500 m (1640 feet) over OM4 laser-optimized fiber. Browse compatible fiber extension hardware in our Extron collection.

Key Features
- Lossless and Uncompressed 4K Transmission — Supports mathematically lossless 4K/60 4:4:4 over one fiber or fully uncompressed 4K/60 4:4:4 over two fibers, with HDMI 2.0 data rates up to 18 Gbps (6.0 Gbps per color) and Deep Color up to 12-bit.
- Buffered HDMI Input Loop-Through — A local HDMI output drives a local display for monitoring or content sharing without a separate distribution amplifier, supporting resolutions up to 4096x2160.
- EDID Minder and Key Minder — EDID Minder maintains continuous EDID communication so sources power up and output reliably, while Key Minder authenticates and maintains continuous HDCP 2.3 encryption for quick, reliable switching.
- Integrated USB Signal Extension — Extends USB 3.0, 2.0, 1.1, 1.0, and HID peripherals over the same fiber as video and audio through a one-port USB HID and one-port USB 2.0 connection, eliminating separate USB extenders for KVM applications.
- USB HID Device Class Filtering — The USB HID port applies factory-set device class filtering to restrict connected devices to HID types, preventing unauthorized data transfer in secure environments.
- Audio Embedding and Adjustment — Analog stereo audio is converted to digital HDMI audio with adjustable gain and attenuation (-18 dB to +24 dB in 1 dB steps) and an analog audio return channel for a remote source.
- Bidirectional Control Extension — Transmits RS-232 (pass-through up to 115,200 baud) and IR control signals over fiber for remote AV device control from the transmitter or receiver end.
- Ethernet Monitoring and Control — A 10/100/1000Base-T RJ-45 port enables proactive monitoring and management over standard TCP/IP networks, with a front panel USB configuration port for setup without rear panel access.
- JITC Certified — Successfully completed interoperability and information assurance testing for government and mission-critical environments, with a TAA Compliant version available.
- Everlast Power Supply — The internal Extron Everlast power supply (100-240 VAC) provides worldwide power compatibility and is covered by a 7-year parts and labor warranty.

Frequently Asked Questions
Which receiver pairs with the FOX3 T 301 MM transmitter?
In point-to-point applications, the FOX3 T 301 MM pairs with the Extron FOX3 SR 301 MM scaling receiver. It can also feed a FOX3 Series matrix switcher for enterprise-wide distribution.
What is the difference between one-fiber and two-fiber operation?
Over two fibers the system delivers fully uncompressed 4K/60 at 4:4:4 (including 12-bit color); over a single fiber it delivers mathematically lossless 4K/60 at 4:4:4, useful where fiber count is limited.
How far can this multimode model transmit?
The 850 nm multimode model supports up to 500 m (1640 feet) over 50 µm OM4 laser-optimized multimode cable. It also works with OM1, OM2, and OM3 fiber at reduced distances. Singlemode models are available for distances up to 20 km.
Can I drive a local display at the transmitter?
Yes. The buffered HDMI input loop-through provides a local HDMI output for monitoring or content sharing without a separate distribution amplifier, supporting 4K/60 video.
Is a TAA compliant version available, and what warranty applies?
A TAA compliant version is available on request. The transmitter carries a 3-year parts and labor warranty, and the internal Extron Everlast power supply is covered by a 7-year parts and labor warranty. Contact Creation Networks for full details.
