Extron FOX3 T 111 MM – Fiber Optic Transmitter for HDMI, Multimode

Product Overview

FOX3 T 111 MM (Multimode), part number 60-1957-31. The Extron FOX3 T 111 is a compact fiber optic HDMI transmitter for long haul extension of HDCP-compliant HDMI video with embedded audio. It delivers mathematically lossless 4K video up to 4096x2160 at 60 Hz with 4:4:4 chroma sampling over a single fiber, using Extron all-digital technology rather than compression. An HDMI input loop-out feeds a local display or confidence monitor at the source position. Multimode and singlemode versions are available to match the installed fiber plant.

Product Description

Once a run exceeds what twisted pair can carry, fiber is the answer, and the question becomes what the extension does to the image. Compressed extension is acceptable in many applications and unacceptable in others, particularly medical imaging, simulation, command and control, and any environment where the operator is looking for detail rather than watching a presentation.

The FOX3 T 111 delivers mathematically lossless transport. Extron all-digital technology carries 4K video up to 4096x2160 at 60 Hz with 4:4:4 chroma sampling over one fiber, with no visually lossy compression stage in the path. Signal support is HDMI 2.0 with HDCP 2.3 at data rates up to 18.0 Gbps, chroma sampling of 4:4:4 or 4:2:2, and color bit depth of 8 or 10 bits per color. Two-channel LPCM audio is embedded.

The HDMI input loop-out is a practical detail that saves a distribution amplifier. At the source position, the loop-out feeds a local display or confidence monitor with the same signal being sent down the fiber, which is common at a lectern, a control position, or a rack where the operator needs to see what is being sent.

Two versions are offered to match the fiber plant. The multimode version (60-1957-31) suits in-building and campus runs on OM3 or OM4 fiber. The singlemode version (60-1957-32) supports longer distances typical of multi-building campus and metro deployments. Both share the same signal specification and use a single SFP fiber connection. Pair with the Extron FOX3 R 111 receiver at the display end.

Key Features

• Mathematically lossless transport — Extron all-digital technology carries 4K video with no visually lossy compression stage in the signal path.
• 4K/60 at 4:4:4 — Supports up to 4096x2160 at 60 Hz with full 4:4:4 chroma sampling over a single fiber.
• Single fiber operation — Uses one fiber strand per link, conserving strand count in the installed plant.
• HDMI input loop-out — Feeds a local display or confidence monitor at the source position without a separate distribution amplifier.
• HDCP 2.3 compliant — Maintains protected content paths for laptops and media sources.
• Embedded audio — Carries two-channel LPCM audio embedded in the HDMI signal.
• Multimode and singlemode versions — Two part numbers match the installed fiber plant for in-building, campus, or metro distances.
• Compact form factor — Small enough for placement at a source position, lectern, or rack without consuming meaningful space.
• SFP fiber connection — A single SFP interface simplifies fiber termination and future optic changes.

Frequently Asked Questions

What does mathematically lossless mean here?

The transport applies no visually lossy compression to the video. The image arriving at the receiver is bit-accurate to the source, which matters in medical imaging, simulation, command and control, and any application where detail rather than general impression is the point.

Should I order multimode or singlemode?

Match the installed fiber plant. Multimode (60-1957-31) suits in-building and shorter campus runs on OM3 or OM4. Singlemode (60-1957-32) supports the longer distances typical of multi-building campus and metro deployments. The two are not interchangeable.

How many fiber strands does a link require?

One fiber per link. That conserves strand count in the plant, which is often the constraint in an existing building rather than distance.

What is the loop-out for?

It passes the source signal to a local display or confidence monitor at the transmitter position, so an operator at a lectern or rack can see what is being sent without adding a distribution amplifier.

What receiver pairs with this transmitter?

The Extron FOX3 R 111, in the matching fiber mode. A multimode transmitter pairs with a multimode receiver; the same applies to singlemode.

Does it support 4:4:4 chroma at 4K/60?

Yes, up to 4096x2160 at 60 Hz with 4:4:4 chroma and 8-bit color, or 10-bit at 30 Hz. Maximum data rate is 18.0 Gbps.

What support does Creation Networks provide?

We can review fiber type, distance, and optic selection for the link before you order, coordinate Extron warranty and RMA handling, and quote at project volume.
