For our network access, we have chosen to follow the path of FTTH technology, currently the most advanced technology, capable of introducing GPON technology (Gigabit Passive Optical Network) and monitoring its evolution.
Open Fiber’s FTTH access network is a passive multi-operator network, which supports “point – multi-point” technologies and provides the use of “point- point technologies”.
OF’s “point – multi-point” architecture is based on the realization of a network in which the optical resources of concentration are assigned to the different operators, while the final connection with the end-user is realised with only one dedicated fiber.
To allow an efficient collection of users, it has been introduced a network element made of a permutation wardrobe (coincidental with the PFS node) which allows the connection, in a flexible way, to every client with the operator’s optical resources with which the service has been contracted.
OF GPON architecture
The evolution paths of the technologies for optical access networks PON (Passive Optical Network) are characterised by an increase of the band to door and the band available for the client.
The evolution of FTTH technology is a key aspect of telecommunication’s industry. Open Fiber’s optic access platform is adaptable according to the evolution of applications in the market and to the future band requests.
The services provided on the PON (Passive Optical Network) configuration network are turned to residential and business users, with connection services in symmetrical and asymmetrical configuration. Thanks to the technology evolution of the PON network use, it will also be possible to offer connections in high backhauling and fronthauling capability for advanced radio mobile systems.
Technologies provided for the FTTH standard are:
NG-PON2 (min 4x10G/2,5G)
In the brackets the maximum speed in Downstream and Upstream are specified.
Open Fiber chose to follow the FTTH technology path for its access network and to introduce the GPON technology as its first step.
A modern Transport Network
Open Fiber is developing a modern national transport network, which allows the collection of the fiber accesses trafficking and deliver it to the operators, ensuring equal access and service conditions regardless of the delivery point, local or remote.
In this sense, the network enables the offer of a complete portfolio of services to tap into the needs of an increasingly more heterogeneous market, from the end-to-end connection with consuming (granted band or minimum latency) Service Level Agreement - SLA - to the future offer of a network and computing infrastructure to host physical and virtual third parties functions; all to improve the Quality of Experience, support video content spread, offer security solutions and the Internet of Things (IoT) platforms.
Open Fiber is drawing up a platform conceived with a convergent, programmable, highly performing and scalable “Carrier Grade” architecture, which allows operators to consolidate and increase the performances of their backbone infrastructures, simplifying management activities and improving the ease of service delivery. This architectural solution is IP end-to-end and will allow the delivery of every kind of service, such as video, mobile, cloud.
Open Fiber’s Transport Network includes only two levels:
- a core or a national backbone network
- a bundling network.
Open Fiber’s latest generation national backbone includes National POP (Point of Presence) distributed to be able to guarantee full national coverage.
The bundling network, formed by Edge’s POP, will provide the necessary Level 2 and 3 functions, as well as the full support to the MPLS transport protocol for advanced services, as L2VPN, L3VPN and multicast, realising a high capability access network point (with uplink to the 100G network) and able to manage customer services.
