European FTTH/B rollout up 6.8%

The FTTH Council Europe’s annual Market Panorama aims to provide a complete summary of the status of FTTH/B in Europe measured during September 2022. The study is based on data and information collected by the European Commission (through DESI studies) and information gathered from local regulators in each country, where available. Data is also gathered through direct contacts with leading players and IDATE partners within countries; information exchange with FTTH Council Europe members; and data per player for FTTH/B and other fibre-based architectures.

According to the Market Panorama released by the FTTH Council Europe at the recent FTTH Conference,

the accuracy of data from Ukraine and as a result, the FTTH Council have removed Russia and Belarus from individual mention in the report due to their actions and support of the invasion of Ukraine. Regarding the specific case of Ukraine, FTTH/B coverage in the country is estimated to be around 67% of total homes in September 2022, but there is no current data on the level of damage caused by the war on FTTH networks in Ukraine and despite seeing reports of amazing efforts to maintain the network as much as possible, it is not yet known how fast these networks can be rebuilt.

The UK is leading the way in terms of homes passed which has accelerated extremely rapidly since the report’s data collection point of September 2022. Full fibre coverage had reached 42% of UK homes, or around 12.4 million, by September 2022, representing an increase of 4.3 million homes between 2021 and 2022. Italy and Germany have also increased the FTTH deployment since 2021, although VDSL technologies remain the most widespread to date. The report notes however, that there have also been significant regional actions this year which impact

as of September 2022, FTTH/B coverage (i.e.

premises passed) in the 27 EU countries (including the UK) was up 6.8% year-on-year, giving a total of 55.3% of premises passed. For the EU 39 countries (including UK) the figures were 5.3% and 62% respectively. Take-up for the EU 27 + UK over the same period however, was a mere 0.4% with a total of 52.8% subscribers as a percentage of homes passed. For the EU 39, including the UK was 1%, with a total of 49.5% subscribers as a % of homes passed.

OIF launches 3.2T CPO implementation agreement

multi-vendor elements to enable co-packaging architectures, including the External Laser Small Form Factor Pluggable (ELSFP); co-packaged 3.2T copper cable assemblies; an operating linear optical module; and a variety of optical connectivity solutions. Richard Ward, technical editor of the OIF 3.2T Co-Packaged Module IA, Astera Labs, commented that considerable progress has been made in co- packaging, and this new IA, along with a collaborative ecosystem meets industry needs, including those of Cloud service providers, as they build their next- generation AI networks.

It can enable optical and/ or electrical interfaces for a 51.2Tbps aggregate bandwidth switch. The new IA includes interoperability specifications for the 3.2 Tbps CPO modules, including: 8 x 400Gbps optical interface options for FR4 and DR4 connectivity 32 x CEI- 112G-XSR host interface (or 32 x CEI-56G-XSR in “backwards compatible” mode); opto-mechanical module specifications; electrical specifications; control and management interface, enabled

innovation and progress in co-packaging, continuously seeking ways to improve and innovate,” said Jeff Hutchins, OIF PLL Working Group Co-Packaging vice chair and board member, Ranovus. “This IA is part of a trio of projects which include the Framework project and the External Laser Small Form Factor Pluggable (ELSFP) project. Building on OIF’s successful track record of coherent and laser module IA’s, it addresses the market need for interoperable integrated optics standardisation identified by the CPO Framework IA.” OIF also recently announced CPO specifications for pivotal

In its first project under the umbrella of the Co- packaging Framework Document, the OIF has launched an industry-first. The OIF-Co-Packaging-

3.2T-Module-01.0 – Implementation

Agreement (IA) for a 3.2Tbps Co-Packaged (CPO) Module defines a 3.2T co-packaged module that targets Ethernet switching applications utilising 100G electrical lanes and provides backward compatibility with 50G lanes. The module definition can be in the form of an optical module or a passive copper cable assembly and provides ~140G/mm of bandwidth edge-density.
