Connectivity and compatibility

This extender kit connects a DisplayPort source to a remote display using singlemode fiber optic cable, ensuring signal integrity over long distances. The transmitter includes a local HDMI output for previewing the source feed, while the DIP switch options allow integration of USB HID devices, IR remotes, or serial control systems through the same fiber link. It supports HDCP 2.2, maintaining protected content without interruption. The kit is compatible with any DisplayPort 1.2 source and display that supports 4K resolution and HDR.

Ideal uses and environments

The B127F-1A1-SM-DD excels in scenarios where the display must be located far from the source, such as airports with flight-information boards, stadium scoreboards, trade show digital signage, or large-scale corporate installations. Its long reach and reliable signal quality make it a strong choice for integrators and IT managers who need a low-maintenance, high-performance solution to bridge control rooms and remote 4K displays. The rugged metal housing and included mounting hardware also support professional installations in demanding environments.

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.
