FIRST ‘SUPERFAST ESSEX’ FIBRE CABINET ARRIVES IN VILLAGE


Gigaclear has installed its first pure fibre broadband cabinet in a village in Essex, UK, under the county’s broadband improvement programme, Superfast Essex. Te cabinet provides 212 properties in Birchanger with a connection


to a pure fibre broadband network, with more properties enabled across the district (Utlesford) in the coming months. Te network is capable of delivering download and upload speeds up to 900Mb/s. Te ultrafast rural broadband network operator is commited


to delivering fibre broadband to more than 4,600 properties in Utlesford, as part of Phase 3 of its work with Superfast Essex. Te £6.8 million contract is funded by an investment from Essex County Council, a local funding contribution from Utlesford District Council, a matching government grant from Broadband Delivery UK and a significant investment from Gigaclear. It is a significant civil engineering project, in which Gigaclear


contractor Kier dug up 5.3km of carriageway, footway and verge to lay more than 6.5km of fibre. Councillor Gagan Mohindra, Essex’s member for economic


development, said: ‘Building a brand-new broadband network is no easy feat, but the long-term benefits to the economy and quality of home life makes it a very worthwhile project for Essex County Council to invest in.’ Drew Ritchie, chief operating officer at Gigaclear added: ‘We believe


passionately in the importance of digital inclusion for all, no mater how rural their chosen home or business is, and we are delighted that our network is bringing world-class broadband speeds to residents of Birchanger, in partnership with Superfast Essex.’


KAIAM’S UK AND EUROPE OPERATIONS BOUGHT BY BROADEX TECHNOLOGIES


Chinese transceiver supplier, Broadex Technologies has acquired the UK and Europe operations of Kaiam. Te struggling division of US- based Kaiam Corp went into administration at the end of 2018, when Blair Nimmo and Alistair McAlinden, of KPMG, were appointed as joint administrators, and 310 of the 338 employees were made redundant. Broadex has formed a UK


subsidiary, ‘tentatively named’ Broadex Technologies UK, for the $5.5m purchase. Te UK business was formed with an additional $10m of Broadex’s funds. According


to the announcement, the acquired assets include the Livingston, Scotland, facility and all equipment related to the business, including inventory, workshop decoration and supporting facilities, alongside any IP and patents. Te acquisition is designed


to expand the China-based company’s manufacturing capabilities of planar lightwave circuit (PLC) chips, and stabilise the upstream supply of related products, at the same time, providing a new production research and development base, and enhancing Broadex’s strategy when it comes to optical chips and related devices.


TENCENT DEMONSTRATES 200G IP OVER DWDM WITH ACACIA COMMUNICATIONS


Chinese conglomerate Tencent has completed an 80km fibre transmission of multiple 200G 8QAM signals over its OPC-4 open line system (OLS) using Acacia Communications’ CFP2- DCO modules on third-party switch platforms. In order to emulate the higher


ORANGE STRENGTHENS PRESENCE IN FRANCE VIA PUBLIC INITIATIVE NETWORKS


Orange is to offer its services in France as an internet service provider (ISP) on all public initiative networks deployed in the market, regardless of the infrastructure operator deploying the network. Te move will expand the operator’s fibre offering, which is currently available for 12 million homes and business premises. Tose in areas served by the networks will eventually benefit from Fiber Orange offers. Tese are already available for more than 500,000 homes and business

premises located in the public initiative network zone. By the end of 2019, they are expected to reach around three million eligible catches in these same areas. Fabienne Dulac, deputy chief


executive officer at Orange France, said: ‘With this decision, we demonstrate our commitment to the deployment of fibre and our desire to support our customers and public stakeholders. It illustrates Orange’s ongoing commitment to fight digital exclusion.’


fibre loss in its metro networks, Tencent added additional 10dB optical attenuators to the tested link, and was still able to achieve error-free operation in all the ports. OPC-4, which was developed by Tencent, meets its SDN requirements for a disaggregated transport network and is fully integrated into the company’s network controller. Tencent believes that this lab demonstration validates the deployment readiness of its IP over DWDM solution using OPC-4 in their metro DCI networks. The demonstration used


Acacia’s CFP2-DCO modules with 50GHz channel spacing and 200G 8QAM modulation, which additionally showcase the


ability to support transmission of up to 19.2T on a single fibre using Tencent’s 96 channel OPC-4 and Acacia’s CFP2-DCO modules. The demonstration is designed to highlight the value of IP over DWDM and disaggregated solutions to cost-effectively meet the growing bandwidth needs of Tencent’s metro DCI infrastructure. Jengyi Geng, senior network


architect at Tencent, said: ‘With Acacia’s 200G CFP2-DCO, our switch platform can support eight ports, for up to 1.6T per line card and our OPC-4 can support transmission of up to 19.2T over a single fibre for metro DCI applications.’ Tom Williams, associate vice


president of marketing at Acacia Communications, added: ‘We believe this lab demonstration underlines the importance of pluggable coherent modules in applications such as Tencent’s metro DCI network, potentially creating opportunities for our NEM customers to offer differentiated solutions in these applications.’
