Quick Method for Drawing Optical Cables in Cable Trays

Efficiently drawing optical cables in cable trays involves using structured cabling software with pre-defined tray types, layers, and routing preferences to minimize manual adjustments and ensure proper alignment.Software-Based Drawing Techniques
  1. Configure Layers and Tray Types Before drawing, set up layers in your CAD or IT Advisor software to separate cable trays from other building elements. Choose the appropriate tray type—perforated, ladder, or solid—based on ventilation and support requirements . Assign a default tray genome or template to streamline repeated use.
  2. Draw Segments and Connect Automatically Cable trays are drawn as individual segments that snap together. Use automatic connection features to join segments at angles, T- or X-branches, and vertical risers. This reduces manual alignment errors and speeds up the drawing process .
  3. Set Routing Preferences Predefine alignment, elevation, offsets, bends, and branch types. This allows the software to automatically adjust crossings, elevations, and segment lengths, improving efficiency and reducing the need for manual corrections .
  4. Vertical Riser and Drop Trays For multi-floor installations, add drop trays or vertical risers by specifying the height and connecting them to the main tray. This ensures proper cable descent and continuity between floors .
  5. Labeling and Documentation Assign names to trays and segments during or after drawing. This facilitates later cable addition, maintenance, and documentation for structured cabling systems .
Physical Installation Considerations
  • Diameter Fill Method: Ensure the tray is sized according to the one-layer principle for optical cables, avoiding overfilling and maintaining bend radius requirements .
  • Securing Fiber Tubes: Use crimping tools or cable ties adjusted to the buffer tube diameter to secure optical fibers without causing stress or microbends .
  • Electromagnetic Protection: If trays are near electrical cables, consider shielding or separation to prevent interference .
Best Practices
  • Draw in 3D view when possible to coordinate with other building systems and avoid clashes .
  • Use sparse or dense drawing modes depending on the level of detail required .
  • Save tray settings for reuse in future projects to maintain consistency and speed up workflow . By combining software automation, proper tray selection, and careful physical handling, you can quickly and accurately draw optical cables in cable trays while ensuring compliance with structured cabling standards and minimizing installation errors.
