In following world trends, cellular telephone operators are constantly increasing their customer base. At the same time, new technologies, such as GPRS and third generation (3G) UMTS, are being implemented in a way to offer applications richer in content and interactivity.
During the evolution of cellular telephone networks, the increase in bandwidth used by the end user - principally generated by new services and applications - directly reflects in different classes of networks such as Access and “Core”.
To support the increase and to also efficiently provide different types of traffic (voice and data) in a convergent network, operators are migrating their medium capacity PDH systems to ring type networks based on SDH and more recently to networks based on IP/ GbE.
In this context, GPON technology shows itself as an excellent solution in the construction of the backhauling of TDM systems and cellular tower packages and BTS up to BSC (base station controllers).
