Convert projects from conceptual or basic design into detailed design:
Translate our proposals to customers into detailed technical designs. Customize-to-order our product portfolio to fulfill our customers needs.
Create manufacturable 3D models, 2D drawings, assemblies, and technical specifications.
Define practical design details such as mounting, interfaces, sealing, cable entry, fibre routing, connector placement, and assembly sequence.
Ensure the design can be built, inspected, tested, and delivered.
Detailed design of hardware:
Design and detail hardware such as:
Fibre optic connection layouts
Cable and fibre routing
Splice plans and splice tray layouts
Junction boxes and connector interfaces
Sensor mounting concepts
Brackets, housings, covers, plates, fixtures, and mechanical interfaces
Assembly and installation details
Create production-ready documentation:
3D models and 2D manufacturing drawings
Assembly drawings
Bill of Materials
Supplier drawings
Technical specifications
Fibre connection details and splice diagrams
Inspection and test requirements
Support Operations and suppliers:
