A structured cabling system is the part of a building that every other system ends up depending on. Data outlets, Wi-Fi access points, IP cameras, AV and building controls all need a horizontal link that stays inside the 90 m permanent link limit, a telecom room close enough to serve it, containment with room for the cables, and a backbone that carries enough fibre with margin to spare. This free Structured Cabling Designer brings those checks together on your own floor plan, following the structure of ANSI/TIA-568, ISO/IEC 11801 and EN 50173.
Load a drawing or start on a blank grid, set the scale, then place the MDF and IDF rooms and draw cable tray, wire basket or conduit routes. Add work-area outlets one at a time or fill an area by density, and every outlet is routed to its nearest telecom room along the containment with vertical drops and service slack. The tool flags links above the amber and 90 m limits and suggests where a new IDF would fix them, prints TIA-606 style labels on the plan and in a cable schedule, packs whole runs into 305 m boxes, and sizes patch panels, switches, managers and racks. It also works out tray and conduit fill, PoE bundle guidance, telecom room size, the fibre backbone with core counts and a link loss budget, and draws a riser schematic with rack elevations.
The tool is built for network designers, ELV and ICT consultants, contractors and installers preparing concept designs, tenders and material take-offs. Lengths, fill limits, PoE bundle sizes, attenuation and application limits use typical values, so check them against the edition of the standard that applies to your project, the manufacturer datasheets and a site survey, and certify every link after installation. Your work saves automatically in your browser, and you can export PNG images, a CSV of the schedule and BOQ, a JSON project file or a printed report.
Structured Cabling Designer v1.0
Plan horizontal and backbone cabling on your floor plan to TIA-568 / ISO/IEC 11801 / EN 50173: outlets, telecom rooms, tray routes, 90 m link check, TIA-606 labels, 305 m box packing, racks, fibre loss budget, riser and BOQ.

- Pick the standard, cable category and jacket at the top, or press ★ Example project to load a sample office floor and see every output straight away.
- Load your floor plan (PNG, JPG or a PDF page) or start a blank grid, then set the scale by clicking both ends of a known dimension.
- Place the MDF and IDF / telecom rooms, then draw cable tray, wire basket or conduit routes as polylines (double-click to finish). Routes that cross or touch join into one network.
- Place work-area outlets one by one, or use Auto-place area to fill a rectangle by density (for example one dual data outlet per 10 m², one Wi-Fi AP per 120 m²).
- Each outlet is routed automatically to the nearest telecom room along the containment, with vertical drops and service slack. Links over the amber or 90 m limit turn amber or red and the tool suggests where a new IDF would fix them.
- Review the cable schedule with TIA-606 labels, the BOQ tabs, tray fill, PoE bundle guidance, fibre loss budget, riser and rack elevations, then save the project, export PNG or CSV, or print the report.
