FTTH Capacity Planning: How to Find Free Cores & Splitter Ports for New Customers

When sales teams receive a request for a new broadband or enterprise leased-line connection, the first question is always: "Do we have spare fiber capacity nearby?" Without clear digital documentation, companies waste thousands on unnecessary cable rolls.

The Cost of Invisible Network Capacity

In many cable networks, operators have 12F or 24F cables running down street corridors where only 4 or 6 fibers are actively utilized. However, because the technicians do not know which cores are free, they pull a brand-new cable from the node.

This unnecessary overbuilding burns capital on optical cable, suspension clamps, and technician labor, while leaving valuable dark fiber unused inside existing sheaths.

Conducting Instant Feasibility with CoreMap

CoreMap provides instant spatial feasibility checks. Enter the prospective customer's address or drop a pin on the map. CoreMap scans all nearby junction boxes within customizable radiuses (e.g., 100m, 200m).

For each junction box, the software immediately displays:

1. Number of available splitter ports with sufficient optical power.

2. Dark / unassigned fiber cores inside incoming distribution cables.

3. Estimated drop cable distance and route path.

Sales representatives can confirm serviceability with the customer during the first phone call, closing deals faster than competitors.
