NeoPhotonics samples 400ZR OSFP coherent transceiver

NeoPhotonics began sampling its new 400ZR ClearLight OSFP transceiver to a leading cloud -related customer.

The new transceiver utilizes NeoPhotonics Silicon Photonics Coherent Optical Subassembly (COSA) and low power consumption, ultra-narrow linewidth Nano-ITLA tunable laser, combined with the latest generation of 7 nm DSP, to provide full 400ZR transmission in a standard data center OSFP form factor.

NeoPhotonics said its new 400ZR ClearLight OSFP transceiver can be plugged directly into switches and router, simplifying data center interconnect (DCI) networks by eliminating a layer of network equipment and a set of short reach client-side transceivers. The new OSFP module is capable of tuning to 75 GHz or 100GHz spaced wavelength channels, as specified in the OIF agreement, and operates in 400ZR mode for Cloud DCI applications.  For longer metro reaches, the module  is designed to support 400ZR+ modes.

This ClearLight OSFP module can also be optionally provisioned to tune over the entire “Super C-Band”, or up to 6.4 Terahertz, increasing the capacity of an optical fiber by up to 50% over standard implementations.  NeoPhotonics provides arrayed waveguide gratings for multiplexing and de-multiplexing with 75GHz and 100GHz wavelength channel spacings, supporting 85 and 64 channels respectively, with filter responses optimized for high baud rate coherent signals.

"This new OSFP module joins our ClearLightTM DCO transceiver line and takes full advantage of our highly integrated and low power consumption Nano-Tunable Laser and Silicon Photonics COSA to enable a full metro coherent transceiver in the form factor and electrical interface designed for short reach interconnections inside the data center," said Tim Jenks, Chairman and CEO of NeoPhotonics. "We are now sampling these OSFP transceivers so that customers can evaluate the simplicity, cost and operating savings that can be realized by plugging coherent optics directly into switches and routers, and we are applying this same technology to additional form factors such as QSFP-DD", concluded Mr. Jenks.

Vodafone supports 5G 0-RAN as its restructures tower business

by Benedict Chua

Vodafone confirmed further activation of its 5G network in the UK, including in Belfast, Edinburgh and Leeds, plus the towns of Cheadle, Rochdale and Stockport in and around Greater Manchester.

Vodafone is also now offering  5G roaming in five locations in the Republic of Ireland. 5G roaming already covers Germany, Italy, Spain and the UK as part of Vodafone’s 5G roll-out.

Vodafone is the first UK company to introduce 5G multi-operator radio access network (MORAN) technology. This enables providers to share the same mobile base station, helping to reduce energy usage and the number of masts needed.

Vodafone UK Chief Executive Officer Nick Jeffery said: “We have started the new year as we mean to go on. We now offer 5G in double the number of places than our nearest rival and we have significantly boosted the capacity of our network. It is ready for the arrival in 2020 of some great new 5G handsets and the next big software release bringing ultra-low latency. Together, these will push 5G to the next level.”

In October 2019, Vodafone initiated trials of OpenRAN in the UK, the DRC and Mozambique. The trial sites across the three countries will provide 2G, 3G and 4G services, with 5G possible over OpenRAN in the future. Vodafone has already undertaken lab trials of OpenRAN with Vodacom South Africa, and in Turkey has deployed the technology to deliver 2G and 4G services to customers in both urban and rural parts of the country.

Vodafone is working with a number of new vendors supplying OpenRAN technology including US companies, Parallel Wireless and Mavenir, and UK-based Lime Microsystems for Open CrowdCell. Vodafone has also become a founding member of the newly annouced 5G Future Forum, which is also backed by America Movil, KT, Rogers, Telstra and Verizon. The mission of this forum is to develop uniform interoperability specifications to improve speed to market for developers and multinational enterprises working on 5G-enabled solutions.

Also of note, Vodafone is currently working to restructure most of its European tower infrastructure into a new, fully independent "TowerCo" company. The goal is for TowerCo to be operational by May 2020. The newly independent company will comprise 61,700 towers in 10 markets with potential proportionate EBITDA of around EUR 900 million. Vodafone said it believes that there is significant scope to generate operational efficiencies and increase tenancy ratios across the portfolio by creating an independent company. Based on market benchmarks for anchor tenant lease rates, existing third party revenues and the attributable cost base, TowerCo could generate proportionate annual revenue and EBITDA of around €1,700 million and €900 million, respectively. TowerCo’s attributable annual maintenance and expansion capex could be up to €200 million.

A future IPO for the new organization is a possibility.

Vodafone has recently announced active and passive network sharing agreements in Italy, Spain and the UK.
