KE1X Fiber HD Video Extender

How to Order

HSL innovative remote Fiber Video Extenders are especially designed for digital signage and conference room solutions.The HSL KE1X (DVI-D) are by far the most advanced fiber video extenders on the market today.

KE1X use a single strand OM4 Multimode SC to SC fiber cable to extend HD-quality video (DVI-D), 10/100 LAN, RS232 and IR to a distance of up to 1,000 meters without any latency or data loss. Their small size, reduced power consumption, superior video quality and LAN extension make them ideal solutions for digital signage and remote conference room extensions.

HSL Fiber Video Extenders are 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 Extenders’ LAN port is fully compatible with IEEE 802.3-2005, 10BASE-T/100BASE-T for extending TCP-based devices to up to one kilometer. KE1X extend both IR traffic for remote control and serial RS232 communication via USB on the TX side.

The 1 kilometer extension makes it transparent to the viewers with video displays 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.
