KE3X Fiber KVM & HD Video Extender

How to Order

HSL innovative remote Fiber Video Extenders are especially designed for digital signage and conference room solutions.

The KE3X can extend HD-quality video over DVI and full-speed USB devices to a distance of one kilometer on a single strand OM4 Multimode SC to SC fiber cable. The HSL KE3X (DVI-D) is by far the most advanced fiber KVM extender on the market today, and is fully compliant with HDMI 1.3a and HDCP 1.3.

The KE3X compact size and attractive pricing make it an ideal solution compared to large, high cost available video extenders.

Its small size, reduced power consumption and superior video quality, make it the ideal solution for remote KVM extension and video conferencing solutions.

The HSL Fiber KVM Extender is extremely low on power consumption using either power over USB (on the TX side) or an efficient 5V wall-mounted power supply (on the RX side) to power all interfaces.

The 1 kilometer extension makes it transparent to the viewers with video displays and USB devices placed where viewing is required, while the corresponding video source equipment is installed in a safe remote location, without interfering with daily work and operations.
