4K HDMI KVM over Fiber

The Black Box KVXLCHF-100 is a KVM extender set that transports HDMI video, USB 2.0, RS-232 serial and analogue audio over a single SFP fibre link. A local HDMI output on the transmitter mirrors the source display at the host side. The kit includes both endpoints, power supplies with international plug adapters and all necessary copper cables for immediate deployment.

Server-room operators and remote-studio users

Suits administrators who need full keyboard, mouse, monitor, serial-device and audio access to a server or PC up to 10 km away over single-mode or multi-mode fibre. Not for buyers who require multi-head video, USB 3.x bandwidth, DisplayPort or DVI native connectors, or IP-based KVM-over-IP management without a separate console server.

10 km fibre reach with SFP flexibility

The maximum extension distance is 10 km, determined by the SFP transceiver chosen and the fibre type installed. This single figure dictates whether the unit spans a rack row, a building campus or a metro link, and it is the primary specification to verify against site cabling before purchase.
