The Business Case for POTS SPLITTER TECHNOLOGY

The Business Case for POTS SPLITTER TECHNOLOGY

The Problem / Motivation:

The primary motivation for placing POTS splitters within the PCP copper cross-connection cabinet rather than the DSLAM cabinet is to reduce labour and material costs.

See diagram below comparing splitter placement within the DSLAM (Figure 1.1) to splitter placement within the PCP copper cross-connection cabinet (Figure 1.2). It can be concluded from this that less tie cables are required in Figure 1.2, therefore POTS splitters give carriers greater flexibility and reduce materials / installation / civil costs.



See diagram (above) comparing splitter placement within the DSLAM (Figure 1.1), to splitter placement within the PCP copper cross-connection cabinet (Figure 1.2).

Further details of cost savings / efficiency gains are:

►► Reduce component costs: tie cables; racks; MDF Blocks.

►► Reduce civil costs: fewer tie cables required between DSLAM and PCP.

►► Reduce installation costs: by using few components within the DSLAM, carriers have greater flexibility.

►► Simplify installation: engineers have less volume of work to do when installing and the task is also simplified.

►► Maximise equipment density: higher density can be achieved in the DSLAM, therefore enabling carriers to service more customers from a smaller footprint, therefore optimising return on investment.

These are key enablers for carriers to more cost-effectively roll-out Next Generation Networks such as VDSL and g.fast and optimise return on investment.


Problem of placing POTS splitter within PCP Copper Cross Connection Cabinet:

By placing POTS splitters within the PCP copper cabinet, carriers face environmental challenges. While these cabinets are sealed chambers, they do not have any heat or humidity control and they are subjected to a constant condensation cycle and temperature cycling, which over time can result in a breakdown of the installed components. Ultimately this results in faults.
