Black Box KVXLCHF-200

Overview

The Black Box KVXLCHF-200 is a fiber-based KVM extender kit designed to let you control a computer or server from up to 30 kilometers away while preserving 4K image quality. It transmits HDMI video at a resolution of 3840x2160 pixels with a 30 Hz refresh rate over single mode or multi mode fiber optic cables. Alongside video, it extends keyboard, mouse, USB 2.0, audio, and RS-232 signals through the same fiber link, enabling seamless remote operation in environments where the computer must be kept separate from the user workstation.

This extender is ideal for settings such as transportation control centers, hospital imaging suites, manufacturing floors, and secure command rooms where sensitive or noisy equipment needs to be housed in climate-controlled racks. The local loopback video port on the transmitter allows for convenient monitoring or troubleshooting directly at the computer location.

Ideal uses and environments

This extender kit is well suited to environments where computers must be physically separated from users due to noise, heat, or security concerns. It works effectively in transportation control centers, medical imaging suites, manufacturing floors, and secure command rooms. The ability to extend signals up to 30 kilometers makes it a strong choice for large facilities or campuses requiring centralized computing resources with remote access points.

Users who need high-resolution video combined with reliable peripheral and audio support will find this kit meets those demands while simplifying cable management and installation complexity.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
