Fiber, cable or copper?

Marcel van Dam

Marcel van Dam

Marcel werkte voor KPN en KPN Mobile in diverse commerciële (management) functies. Vanuit zijn laatste functie als Area Director bij KPN International Consultancy was hij eind 2001 één van de twee oprichters van NTCS. Sindsdien heeft hij NTCS verder geleid en uitgebouwd.

When the new suburb ‘Gold Coast Villas’ on Aruba was conceived, the question arose whether Setar should deploy copper cables or take the opportunity to go for glass fibre (Fibre to the Home or FttH). Following a study on the subject by NTCS, the decision was made to connect Gold Coast Villas using fibre, and that also other new suburbs should follow this decision. After this successful introduction, Setar was confronted with the question on how to roll-out Broadband on a larger scale as a Next Generation Access of NGA; and how this best could be harmonised with existing networks on VDSL and HFC/coax bases.

The request from Setar

Setar has requested NTCS to undertake a study on the short and long-term operational costs and investment requirements for three scenarios:

  1. Continued deployment of xDSL. The distance between DSLAM and client need to be reduced in order to be able to offer higher bandwidth (NGA). This can be accomplished through the implementation of active cabinets on the island;
  2. Continued deployment of glass fibre to (all) existing buildings and addresses;
  3. Deployment and upgrading of the existing Docsis/HFC coaxial cable network in order to deliver higher bandwidth (NGA) to clients.

The approach of NTCS

NTCS consultant Erik van den Oever commenced with a thorough analysis and inventory check of the existing network. Following this, and with close participation of Setar, he defined the objectives of the study and the selection of scenarios to be taken into consideration. Based on the obtained information, Erik was able to develop a model through which the economic parameters of the various scenarios could be compared. In conclusion, the economic results, combined with the related technical/operational aspects, were presented; and resultant conclusions and recommendations were evaluated with Setar management.

Results for Setar

The models developed by Erik have enabled Setar to compare scenarios; and based on this to make important strategic decisions on investments and developments in the access network, on short term; while also supporting an overall strategy for the longer term.

“With the results of the elaborate study and the worked-out scenarios of  NTCS, we feel confident that we can make the right strategic decisions regarding the further development of our access network; and are able to make sensible and future-proof investments therein. Raul Ponson (CTO Setar)

“Setar is commendable for a solid business development, and a sensible mix of innovations and deployment of existing resources, in order to keep abreast with customer demands. A good example for the region! “Erik van den Oever
