The architecture of the operator’s network
The Three Pillars of Connectivity
We integrate technologies from leading global manufacturers to build a robust and flexible architecture divided into three main levels:
Data Network
The infrastructure in the core nodes intelligently manages huge flows of information and can be compared to the “heart” of the system.
High-performance routers and switches that provide lightning-fast traffic routing with minimal delays.
Integrated Cybersecurity: Next-generation firewalls (NGFW) that guarantee data integrity and protection against complex threats.
Access Network
We provide connection to the end user using the most advanced technologies on the market
FTTR (Fiber to The Room)
The latest generation of connectivity, which brings fiber optics to every point in the building for guaranteed speed in every room.
PON (Passive Optical Network)
An efficient and energy-saving technology for direct optical connection without the need for intermediate active power supply.
Mobile Technologies (3G/4G/5G)
Full support for next-generation wireless networks, enabling mobility and mass connectivity of IoT devices.
Transmission Network
Provides long-distance connectivity with uncompromising bandwidth.
DWDM (Dense Wavelength-Division Multiplexing): Innovative technology for multiple compression of optical signals. It enables the transmission of terabits of information over the same optical fiber over enormous distances.
Optical Connectivity: Building backbone networks that are future-oriented and resistant to external influences.
