Orange Polska Tests Seven-core Fibre Reaching 11.2 Tbps

Prysmian Group Extends Cable Range for FTTx and 5G Networks

Orange Polska’s Innovation Lab, together with Infinera and InPhoTech group, tested multi-core fibre and Infinera’s ICE6 800G technology. Infinera claims the throughput obtained during the tests was seven times greater than the maximum that can be achieved today using a standard fibre optic cable. Developed within the

Prysmian Group has extended its Sirocco HD range of microduct cables to include a 576 fibre optic cable in a diameter of 9.5mm, providing a fibre density of 8.1 fibres per mm2, and is installable into a 12mm duct. Sirocco HD microduct cables utilize Prysmian’s BendBright-A2 200µm single-mode (ITU-T G.657.D, G.657. A2) bend insensitive fibre, providing a solution that’s ready for evolved systems and is future-proof. Available now in fibre counts from 96 to 576 and conforming to international standards for

simultaneously. This means that its capacity is seven times greater than that of a standard

optical and mechanical performance, the Sirocco HD cables also benefit by the use of Prysmian’s PicoTube technology making them up to 20% smaller than previously available microduct cables. This makes it possible to install more fibres into congested duct space, and enables the use of smaller ducts for new installations, resulting in lower installation costs and the use of less raw materials. This provides benefits for both the total cost of network deployment and the environmental footprint.

telecommunications fibre. Such optical fibres will be produced in Lubartów by IPT Fiber from InPhoTech group. Infinera says tests have shown that the its hardware allows for 800Gbps data transmission in a single transmission channel. The experiment, conducted in collaboration with Orange, used two channels sending data at a speed of 1.6Tbps in each of the seven cores simultaneously. This gave a total transmission of 11.2Tbps.

Maria Curie-Skłodowska University in Lublin and with the support of the Photonics and Fibre Optics Cluster, the multi-core fibre allows transmission in seven parallel cores

Nexera Gets EU Funding for Rural Fibre Rollout

on the Polish market, confirming the wide development prospects. “Our success is supported by a well- developed business plan, a real and effective company strategy as well as an innovative way of operating our organization, based on the “agile” model, which has in many respects become a benchmark for other operators in the market,” said Jacek Wiśniewski, president of the Nexera Management Board. “We are a relatively small organization, while

in Nexera Regions. The list of lenders includes The European Investment Bank, PKO BP Bank, Santander, BGK and ING. The funds obtained will allow Nexera to pass more than 700,000 addresses that will ultimately be within the range of the operator’s fibre-optic network. In June of this year, Nexera purchased fibre-optic infrastructure from IT Partners Telco, operating locally under the Navu brand. The acquired network consists of more than 5,000 households located in Sandomierz.

Polish operator Nexera received over US$266 million in financing from a consortium of banks including around US$85 million from the European Investment Bank for the development of fibre- optic networks in rural Poland. The funding, in the form of a loan, will be allocated to investments in the development of FTTH networks in the regions. When comparing the size of the company to the amount of the funds made available, Nexera says it is an unprecedented event

the debt financing we receive places us at the level of the largest players in the country. This is a clear success in the Polish market, which shows that we are a reliable organization with huge potential, as confirmed by leading financial institutions,” said Paweł Hordyński, Member of Nexera’s Financial Management Board. The financing will be provided in the form of an overdraft facility and an investment loan to be used for the development of fibre-optic infrastructure
