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).



Solutions and Products from Padtec:
   
LightPad i1600G Platform:
Padtec’s LightPad i1600G Platform is an optical integrated transport system of high capacity and low latency and can be applied not only in long distance networks (Backbone, Long Haul and Ultra Long Haul) but also in metropolitan and storage networks –SANs.
The platform incorporates two fully integrated technologies: DWDM - High Density Wavelength Division Multiplexing and CWDM - Coarse Wavelength Division Multiplexing.

FlexPad 8800 Platform:
The FlexPad 8800 Fiber to the User (FTTU) platform is the state of the art solution from Padtec for Gigabit Capable Passive Optical Network (GPON) systems with residential and commercial applications. Built based on ITU-T recommendation G.984, the FlexPad 8800 platform is capable of transporting triple play (voice, data and video) services through optical fiber at rates of 2.5 Gb/s for up to 20 km.
