The new 50G-PONPON PON stands for Passive Optical Network, which describes all types of optical networks that have no active equipment between the start and end point. One of these is the network used to bring the fiber-optic link to the end-user by means of point-to-multipoint architecture in which a single fiber is used to reach several recipients via non-powered optical splitters. technology will enable OF’s fibre infrastructure to support the development of the most advanced digital services and the connection of 5G mobile networks. 

Open Fiber is among the first companies in Italy to have tested in a controlled environment the new 50G-PON (50 Gb) broadbandBroadband The term broadband, in telecommunications, generally refers to the transmission and reception of information data at a connection speed of over 144 kb/s. Broadband organises different channels, conveying different content in the form of data, such as Internet radio, animation, audio files and high-definition video. access service, by which is possible to achieve speeds of up to 50 Gbps (500 times greater than 100Mbps) on the access networkNetwork In computer language, the term network defines a set of hardware and software devices which, when linked together, enable the exchange and sharing of resources, data or information. In a computer network, the devices that generate, route and terminate data are called network nodes.. Test results show the huge potential of this technological upgrade in terms of bandwidth and latencyLatency This term indicates the time lapse between the stimulation of a system and the observation of the resulting effect. In telecommunications, by extension, it refers to the time it takes for a data packet to travel from the source computer to the destination computer. times of a few tens of microseconds. 

These parameters will be crucial in order to continue to meet users’ needs in terms of quality of experience and speed, even more considering that they are constantly and rapidly growing: the 2/2023 AGCOM Communication Markets Monitoring System shows that average monthly traffic per user on the fixed network increased by +102.8% in 2022 compared to 2019. Moreover, this new technological frontier will open up to new service scenarios and will play a crucial role in binding access network elements in 5G mobile networks. Next-generation mobile networks require transmitting antennas densification (microcells) and must have a large transmission capacity. Thanks to 50G-PON technology and the widespread reach of the PON network, the FTTHFTTH “Fiber to the Home” is the technology that connects POPs, located in exchanges, to end users’ property units with fiber optics. access network will become a platform for achieving fixed-mobile convergence, becoming an important enabler for new applications that will travel on the 5G network, from home automationHome automation Home automation is a field that studies technologies to improve quality of life in the home and automate its management as much as possible. It requires a strongly interdisciplinary approach since it combines architecture, building and energy engineering, electronics, IT and telecommunications. Home automation makes it possible to build a smart home in which, for example, switching on lights, opening doors and shutters, managing air conditioning, security systems and communication systems communicate internally or externally, including via mobile phones, smartphones and the Internet. to assisted driving, to the metaverse and AI.

The experimentation also demonstrated the possibility of running the new 50 Gb service in parallel, and without interference, to the other services already offered by the company (XGS-PONXGS-PON An acronym for 10 Gigabit Symmetric Passive Optical Network, the evolution of GPON technology that enables connection speeds of up to 10 Gigabits per second in both downstream and upstream, as specified by the ‘S’ for Symmetric. This is the main evolutionary step of GPON after XG-PON, which allows a maximum speed of 2.5 Gbps upstream and a maximum speed of only 10 Gbps downstream. The increase in maximum supported upload capacity is one of the most important features of XGS-PON, which is set to become the mainstream technology of the coming years., i.e. 10 Gb).

“Open Fiber has always been a pioneer in the search for cutting-edge technological solutions that enable ever greater capacity and speed in data transmission,” comments Guido Bertinetti, Director of Network & Operations of Open Fiber. The success of this experimentation will soon allow us to quickly provide our partner operators with a new standard to offer their customers, companies and public administrations, capable of supporting both current and future advanced digital services.” 

About Open Fiber 

Open Fiber was established to build ultra-broadband fibre-optic network (FTTH) infrastructure throughout Italy. The goal is to ensure coverage of Italy’s main cities and to connect rural areas through an ultra-broadband fibre network, providing increasingly advanced services and functions for citizens, businesses and the public administration. Open Fiber is a wholesaleWholesale Open Fiber is a ‘wholesale only’ operator, i.e. it operates exclusively in the wholesale market, offering access on fair and non-discriminatory terms to all interested Market Operators.-only operator, it does not sell fibre services directly to the end customer but makes its infrastructure available to all interested operators on equal terms. With over 15.5 million ultra-broadband-connected property unities (P.U.P.U. Property unity.s), Open Fiber is the leading Italian FTTH fibre optic operator and among the leaders in Europe.
