Description
Usefully open source
Modular design
Easy to modify & adapt
For scientific research and experimentation
KORUZA innovates the design of a free-space optical communication system reusing mass produced Small Form-factor Pluggable (SFP) electro-optical transceivers, combining the latest advances in low-cost 3D printing using the Fused Deposition Modelling (F DM) method with bare-minimum custom electronics design.
DIY friendly open-source release together with a complete kit of assembly parts as well as detailed on how to properly assemble and test the system, is released. You can preorder kit at our partner company . KORUZA is on GitHub, using best practices of software design to allow colaborative editing.
KORUZA Features
Data transmission at a capacity of 1 Gbps
The capacity of 1 Gbps is sufficiently high to support large number of moderate users or basic access capacities and can thus be used to build much larger networks then with existing low cost wireless systems.
Capability of bridging a gap of 100m at 1Gbps with an optical link margin of 20dB
Low-cost SFP modules wavelength multiplexed for single-mode fibre use in the 1300nm – 1500nm range have proven to be cost/performance optimal design choice with approximately 20dB optical link margin and with less then 1dB attenuation over short range FSO paths.
Low-cost
While free-space optical technology has been around for decades, it has been always extremely expensive and built for enterprise and service provider markets. A novel and innovative approach to designing such system has been introduced, significantly reducing the engineering effort and material costs.

3D Printable
Design relies on the use of low-cost 3D printing technique of hot extrusion of plastic materials, as it enables the construction of rigid mounting assemblies as well as precise micrometer grade precision linear and kinematic alignment modules.
Modular design
The fully modular mechanical design interconnected with stainless steel rods now enables modification for a variety of use cases. 3D printed parts are designed in OpenSCAD environment, enabling straightforward modification for everyone as well as simplified modification to insure a perfect fit on variety of 3D printers.
Urban environment communication backbone
Primarily designed for urban environments, where Wi-Fi networks suffer from RF spectrum congestion and deploying wired is extremely expensive. KORUZA is resilient to these problems as its light beam is highly collimated, thus numerous units can coexist in a dense urban area, where the demand for capacity is high and distances are relatively short.
FSO system testbed
Suitable for the scientific community to modify and adapt, creating a modifiable testbed and thus providing a platform for experimentation.
