  1. Enter Total Ports Needed — the number of active fiber connections to terminate.
  2. Select Connector Type (LC, SC, or MPO) and Panel Size (rack units) for the panel form factor.
  3. Set Reserve Capacity (%) — 20–30% spare is common for future growth.
  4. Review Panels Required, Total Rack Units, Total Port Capacity, Spare Ports, and Splice Trays Needed.
  5. Use Total Fiber Strands to order the correct quantity of fiber pigtails and patch cords.
