BT and Huawei to create photonics dream team at Cambridge University

BT and Huawei plan to establish a joint research group at the University of Cambridge with £25 million in funding and contributions over the next five years.

The collaboration will bring together ‘five to ten’ researchers – from BT Labs, the Huawei R&D Team and academics from the University of Cambridge – to explore new communications technologies that have the potential to unlock economic benefits for UK businesses and organisations.

Telefonica pioneers plastic optical fibre for home networks

Spanish incumbent Telefónica has successfully completed what it describes as a ‘pioneering’ project using plastic optical fibre (POF) in a home network that guarantees gigabit speeds to the customer.

Telefónica has not confirmed a commercial launch date, but online reports suggest the technology could be rolled out to consumers next year.

Photonics researchers make one chip to rule them all

A multifunctional silicon photonics integrated circuit that can be programmed to perform a variety of different functions has been developed by researchers from Spain and the UK.

This is “the first photonic integrated chip that enables multiple functionalities by employing a single common architecture”, according to researchers from the Silicon Photonics Group at the Optoelectronics Research Centre (ORC), University of Southampton, and from the Institute of Telecommunications and Multimedia Applications (iTEAM) at the Universitat Politècnica de València,

Fixed wireless meets optical access in Nokia Wireless PON

There’s a new kid on the access block and it’s a form of fixed wireless called WiGig. Nokia has integrated the new wireless technology into its optical access equipment, to provide operators with another option for delivering gigabit services to the home.

Nokia says it’s the first to include WiGig technology with passive optical network (PON) equipment. Pilots, commercial trials and general product availability are planned for 2018, the company added.

Lightwave Logic champions polymer-based modulators

Electro-optic polymers could help other optical materials become more successful, according to Lightwave Logic, a development stage company.

Lightwave Logic has developed a high-performance Mach-Zehnder polymer modulator suitable for 50Gb/s modulation, the company announced at ECOC 2017 in Gothenburg Sweden. This breakthrough will enable arrays of 4 x 50G polymer modulators, which can be combined with PAM-4 encoding to build 400Gb/s data centre optics.

CWDM8 MSA targets compact lower power optics for 400G

The CWDM8 multi-source agreement (MSA) Group has been formed to define optical specifications for 400G singlemode optics using 50G per wavelength and non-return-to-zero (NRZ) optical modulation.

The consortium aims to address what they see as a near-term need for lower power and more cost-effective options for distances of 2km and 10km within data centre and campus networks. This will support the deployment of 12.8Tb/s Ethernet switches and other advanced networking equipment with 50G electrical I/O.

100G Lambda MSA focuses on serial 100G optical links

The desire for faster data centre optics appears to be outpacing the standards process. As a result, 22 companies have joined forces to speed up the development of 100Gb/s serial optical interfaces.

The 100G Lambda multi-source agreement (MSA) group is developing specifications for optical interfaces based on 100Gb/s per wavelength over duplex singlemode fibre. These new optical specifications are targeting 100 and 400 Gigabit Ethernet applications in the next-generation of networking equipment.
