Most connections between ARNES network PoPs are implemented using leased optical fibres.
The cost-effective Ethernet protocol is used to provide connections with capacities of 10 Gb/s or 1 Gb/s.
The backbone network is hybrid. It supports both point-to-point and IP-connectivity. Both types of service are implemented using CWDM or DWDM technologies, which enable the transmission of multiple simultaneous communications channels over a single optical fibre. The DWDM equipment used enables up to 16 simultaneous 10 Gb/s channels, while CWDM enables up to four simultaneous 1 Gb/s channels.
IP-connectivity services are based on powerful routers that support both IPv4 and IPv6.
The use of redundant connections, reliable equipment and advanced monitoring and administration mechanisms ensures that services operate reliably.
The backbone is based on wavelength transparent fibre optic. CWDM and DWDM technology running on leased optical fibres. High-speed connections of 1 Gb/s or 10 Gb/s Ethernet are established between PoPs.
