AVPro Edge 8K 48 Gbps Fiber Optic Extension Kit with USB, eARC & Ethernet

Product Overview

The AVPro Edge 8K 48Gbps Fiber Optic Extension Kit is a full HDMI 2.1 extender kit for transmitting ultra-high-bandwidth video and data over fiber optic cable. It supports 8K at 60Hz and 4K at 120Hz, delivering the complete HDMI 2.1 feature set — including eARC, USB extension, and Ethernet pass-through — over a fiber link, making it the correct solution for installations that require the full HDMI 2.1 specification at distance. AV integrators specifying 8K-ready infrastructure, high-refresh-rate 4K gaming environments, or production systems requiring the full 48Gbps HDMI 2.1 pipeline will find this kit addresses all of those requirements in a single kit. It is the solution when standard 18Gbps fiber extenders are insufficient for the signal chain.

Product Description

HDMI 2.1 at 48Gbps is substantially more demanding than HDMI 2.0 at 18Gbps. Fiber optic transmission is the only medium that reliably handles this bandwidth at installation distances, which is why this kit uses fiber rather than copper. The kit transmits the full 48Gbps HDMI 2.1 signal without downgrading color space, refresh rate, or HDR metadata, preserving the fidelity required for 8K content or 4K 120Hz high-refresh-rate applications.

eARC (Enhanced Audio Return Channel) support allows high-bitrate audio formats — including Dolby Atmos object-based audio — to return from the display to the AV system over the same fiber link used for video. The USB extension port extends peripheral connectivity to the remote display location, enabling keyboard, mouse, and HID device use at the display end without a separate USB extension infrastructure. Ethernet pass-through delivers network connectivity at the display location over the same fiber cable, which is particularly useful for smart display management or network-connected devices at the remote end.

HDR formats including HDR10, Dolby Vision, and HLG are all transmitted intact through the fiber link, ensuring the display receives the full HDR signal chain without any stripping or downgrading. HDCP 2.3 compliance covers all current content protection requirements.

Key Features

• HDMI 2.1 at 48Gbps — full HDMI 2.1 bandwidth, supporting 8K@60Hz and 4K@120Hz without compression or bandwidth reduction.
• Fiber Optic Transmission — long-distance, interference-free signal delivery over fiber, the only reliable medium for 48Gbps at AV installation distances.
• eARC Support — Enhanced Audio Return Channel for passing Dolby Atmos, DTS:X, and other high-bitrate audio formats from display to AV system.
• USB Extension — peripheral connectivity at the remote display location for keyboard, mouse, and HID devices.
• Ethernet Pass-Through — network connectivity at the display end delivered over the fiber cable.
• Full HDR Support — HDR10, Dolby Vision, and HLG all transmitted intact through the fiber link.
• HDCP 2.3 — full compliance with current content protection requirements.
• Kit Format — ships as a complete transmitter and receiver pair with all necessary accessories for a single fiber run.

Typical Applications

• 8K display installations in command centers, broadcast facilities, and premium AV environments requiring fiber at distance
• 4K 120Hz high-refresh-rate gaming or simulation environments where full HDMI 2.1 performance is required at the display location
• Production studios and post-production suites requiring the full 48Gbps HDMI 2.1 pipeline from source rack to reference monitor
• Executive boardrooms and premium conference rooms specifying 8K-ready infrastructure for future-proof display systems
• Large venue installations where the display is too far from the source for copper HDMI 2.1 cables
• Control rooms requiring USB peripheral access and Ethernet at the display end without separate extension infrastructure

Frequently Asked Questions

Why is fiber required for 48Gbps HDMI 2.1 at distance?

Standard copper HDMI cables lose signal integrity rapidly beyond 3–5 meters at 48Gbps. Fiber optic cable does not suffer from the same bandwidth-over-distance degradation, making it the only practical medium for full HDMI 2.1 at AV installation distances.

Does this kit support 4K at 120Hz?

Yes. The full 48Gbps bandwidth of HDMI 2.1 allows 4K@120Hz in addition to 8K@60Hz, making it suitable for high-refresh-rate display applications.

What is eARC and why does it matter?

eARC (Enhanced Audio Return Channel) is the HDMI 2.1 audio return standard. It supports high-bitrate audio formats including Dolby Atmos and DTS:X — formats that the older ARC standard cannot carry. On this kit, eARC returns audio from the display back to the AV system over the same fiber cable used for video.

What USB devices are supported through the USB extension port?

The USB extension supports keyboard, mouse, and standard HID peripherals at the display end. Confirm maximum USB extension bandwidth with AVPro Edge product documentation for specific peripheral compatibility.

How does this differ from AVPro Edge's 18Gbps fiber kit (AC-EXO-444-KIT)?

The AC-EXO-444-KIT operates at 18Gbps (HDMI 2.0) and supports 4K@60Hz 4:4:4. This kit operates at 48Gbps (HDMI 2.1) and additionally supports 8K@60Hz, 4K@120Hz, eARC, USB extension, and Ethernet — features that require the full HDMI 2.1 specification.

Is a specific fiber type required?

Fiber type requirements depend on the distance of the run. Refer to AVPro Edge product documentation for supported fiber specifications, or contact Creation Networks for installation planning guidance specific to your project.
