This calculation estimates the economic implications that an upgrade to DOCSIS 3.1 can incur in an existing network. It is a guide and assumes that coaxial cables can be reused.
The CAPEX (total investment), is based on a rough estimate of the total cost of active and passive hardware in the network and its planning, administration and installation. It is not an offer and DKT A/S is not liable in any way. The numbers are based on inspiration and experience from real-life upgrades, but local circumstances and requirements must be considered prior to making a more accurate estimate.
A further significant reduction in CAPEX is possible if a budget exists for node split/reduction in subscribers per segment. This budget must be deducted from the estimated CAPEX, as this is no longer necessary with the sufficient capacity provided by DOCSIS 3.1!
The OPEX (Operating expenses) is based entirely on maintenance of the passive distribution network, such as taps/splitters. At least 8% of the population of passives must be maintained each year. Experience shows that the maintenance consist of:
This can all be avoided by using the DKT “Signia” distribution passive series. More than €2 can thus be saved per subscriber/year, which neutralizes the extra investment within year 1!
In addition to the calculated OPEX savings, there is a long list of additional savings. These are not included in the calculation, among others:
