apredna rješenja za nove tehnologijeN

Pojavom novih širokopojasnih usluga (brzi pristup Internetu, video na

zahtjev, učenje na daljinu, kućna kupovina, TV prijenos, rad na daljinu ..) te

samim povećanjem količi

) postavljaju se sve veći zahtjevi prijenos podataka.

Zahtjev za većom brzinom prijenosa nameće potrebu veće širine

prijenosnog pojasa kako bi se što više informacija po jednom kanalu moglo

prenijeti u što kraćem roku postigla zadovoljavajuća kvaliteta usluge

(QoS). Danas se teži implementaciji xDSL tehnologija koje nam osiguravaju

veliku širinu prijenosnog pojasa.

Advanced Solutions for New Technologies

The appearance of new broadband services (quick access to Internet,

video at request, learning at distance, home shopping, TV transmission,

working at distance…), and the very increase of the daily exchanged

information quantity (Internet, e-mail) poses increasingly higher require

ments on the data transmission. The required higher speed of transmission

imposes the need for a broader width of the transmission band which

supports the shortest transmission of information per one channel and the

achievement of the satisfactory quality of the service (QoS). Nowadays, the

emphasis is laid on the implementation of xDSL technologies which secure

the broad width of the transmission band

relatively small investments

quick connection and users support

simultaneous analogue and digital transmission

adaptable speed of information transmission

By means of sophisticated modulation schemas DSL (Digital SubscriberLine) technology conveys broadband services into our homes and into various business entities (companies, industry, state institutions, schools…).

The existing network infrastructure does not meet the actual transmissionneeds. In order to increase the transmission capacity and improve the performances of the very network, the existing cable infrastructure should betested and at least 500 m of the access segment of the network should beexchanged by the new xDSL cables. However, considering the daily increased number of the users in the system, a partial exchange of the infrastructure soon won't be able to meet the transmission needs. The bestsolution is the exchange of the entire network by the new xDSL cables, asthe present investment into the network secures the capacities for thefuture needs, and in the end reduces the expenses and enables thebroadening of the network to the new users and the new services withoutfurther investments.

Elka kabeli d.o.o. has designed, tested and produced the newest genera

tion of the cables, able to meet the present need of the xDSL technologies.
