Investment for FTTH is 10 times or more than that for plain DSL.
We are assuming the copper plant is already there otherwise I will respectfully disagree. However the economic is not as simple as you might think. Lets do some calculations. Assume we can build the fiber plant for 1 million USD (*). This fiber can be depreciated over 25 years. That means we only take USD 40,000/year of the company profit. The copper plant is already there but the DSLAM is missing. Assume USD 100 per port plus USD 100 per DSL CPE. This equipment can only be depreciated over 5 years. With 1700 ports this gives USD 68,000/year of the company profit. Not claiming these number are anything but fantasy as I know nothing about the layout of the project. Just illustrating that sometimes more money now does not necessary means less profit for a company. (*) yes 1700 installs could be done for that in optimum circumstances. It could also be much more expensive, all depending. Regards, Baldur
