KORUZA v1

The low-cost, open-source and open-hardware wireless optical system where KORUZA began.

From a student idea to an open testbed

KORUZA started in 2012 as VALET, a Very Affordable Laser Ethernet Transceiver, developed by Luka Mustafa with Dr. Benn Thomsen at UCL in London. The idea was to reuse mass-produced SFP fibre transceivers and 3D printed optics to bring free space optics to community networks at a fraction of the usual cost.

Five prototype generations followed. KORUZA 1.0, released in 2015 for scientific research, was fully modular, designed in OpenSCAD and published under the CC BY-SA 4.0 licence, with a complete assembly kit and step-by-step instructions so researchers could build, understand and modify it.
