TIM presents the Magnifica fiber offer: FTTH on XGS-PON available in some of the exchanges in 11 Italian cities.For the supply of FTTH (Fiber-to-the-Home) connectivity, the Italian telecommunications operators have up to now primarily used the GPON (Gigabit-capable Passive Optical Network) technology which allows to ensure end users up to 2.5 Gbps. downstream and up to 1.25 Gbps.In another article we have seen what XGS-PON is and what are the differences compared to GPON.The most important technical peculiarity of XGS-PON in terms of subscribers to the fiber optic service is the possibility of having a symmetrical connection up to 10 Gbps, therefore in both directions.TIM announced today the availability of its Magnifica offer based on XGS-PON technology.In the TIM centers of Italy where Magnifica can be activated, each user can transfer data up to 10 Gbps downstream and 2 Gbps upstream.The company indicates the cities in which it is possible to request Magnifica in this first phase of experimentation: Milan, Turin, Trento, Trieste, Bologna, Florence, Rome, Naples, Cagliari, Taranto and Brindisi.It must be said that not all the users certified on the TIM exchanges of the various cities are currently covered: the online verification tool allows you to establish whether the FTTH XGS-PON fiber has already been reached.The offer up to 10 Gbps in downstream provides for a monthly fee of 49.90 euros and includes the supply of a WiFi 6 4x4 dual-band 10 GbE compatible router.TIM indicates that an Ethernet LAN port can be transformed into WAN in wholesale scenarios.The router also integrates two USB ports (one USB 3.0 and one USB 2.0) as well as two FXS for connecting phones.From a purely technical point of view, as explained at the time by TIM itself, the operator makes GPON and XGS-PON coexist on the same fibers: "the XGS-PON and GPON technologies use non-overlapping spectral bands. This feature allows the coexistence of the two systems on the same PON tree. As part of the experimentation, coexistence is implemented through the aid of a WDM1r filter, which has the task of multiplexing / demultiplexing the upstream and downstream bands of the GPON and XGS-PON systems ".Source: TIM.The diagram shows the frequencies used and the approach used by TIM for the FTTH GPON and XGS-PON fiber.A passive optical network creates a point-to-multipoint connection: the "point" is an operator's apparatus called Optical Line Terminal (OLT) placed for example at the exchange while downstream devices are installed at the end customers (ONT , Optical Network Terminal or ONU, Optical Network Unit).An optical tree or PON tree is connected to each of the ports available on the OLT, to which a certain number of users are connected according to the splitting factor decided by the telecommunications operator.The maximum speed allowed by GPON or XGS-PON is shared by the users connected to the shaft: inside road cabinets or boxes placed under the road surface, further splitting can be carried out at an optical level by applying further branches on the PON shaft.Generally, the splitting levels applied are at most two.With TIM Magnifica nothing changes on the subscriber user side: at his real estate unit the operator will install an ONT that performs the optical / electrical conversion.Downstream of this device it is possible to use a router which must be compatible with 10 GbE and which TIM supplies.We have seen how routers such as the FRITZ! Box 5530 Fiber already exist that allow you to eliminate the ONT also compatible with XGS-PON.AVM had confirmed that FRITZ! Box 5530 Fiber is ready for the Italian FTTH fiber market but that end users cannot currently benefit directly from it because it is a device intended only for the provider market.IlSoftware.it is the Italian website about software.It offers news, articles, tips, insights and reviews on the world of software and technology.A reference point for technicians, professionals and SMEs that helps to make the right choices, solve problems and optimize workflows.To improve the business.We are the first to be demanding, like our readers.© 2001 - 2022 All Software by Nasi Michele - VAT: 02472210547 - All rights reserved - Privacy - Cookie information - Conditions - Credits - ADV Preferences
