The fiber optic substitute ADSL II
For Digital Future | January 29, 2008
The fiber optic filament is a flexible circular section made of some kind of glass or plastic capable of carrying light beams on the inside. It is also necessary to have a light source that emits a highly directional beam, so that they can be introduced into the optical fiber with maximum efficiency, as they have a very small diameter, a fraction of a millimeter or so. The LEDs are used and lasers.
The fiber optic main disadvantage is that you can not take advantage of the copper cables or other connections exist and therefore we must pierce the street to get across the wires. Moreover, the fibers are very sensitive and can break easily. Moreover, it takes some doing expensive transmitters and receivers that the installation is quite expensive, about 400 euros if not the facility. This expenditure will be borne by the company providing the service.
From April phone will make a pre-commercial experience in Madrid and in 2008 there will be more than 470 plants compatible with this technology all over Spain. We must emphasize what makes these tests telephone with a bid of 30Mbps downlink and 1Mbps upload, minimum speeds, although it is expected to be low cost and technical problems that are expected as this is a period of pruevas.
Looking over the Internet one can find offers from other countries, and not to be biased and make an offer to the United States or Japan, where they thousand vaults | turns to the technological infrastructure of Spain, you get a Numericable in France. This company offers 100Mbps downlink and 5Mbps rise by about 20 euros.
