Verizon celebrates successful 400Gb/s field trial

Verizon has completed a successful field trial delivering live 400Gb/s Ethernet traffic on a single wavelength between MPLS Core routers over its packet-optical network.

The trial demonstrated the interoperability between equipment from two different suppliers – Ciena and Juniper – alongside the capability to quadruple the typical capacity carried on one wavelength.

Silicon photonics to capture almost $4 billion of optical transceivers market by 2025

Silicon photonics is on the verge of experiencing dramatic uptake in optical transceivers, market research firm Yole Développement has reported, with the technology set to capture 35 per cent – almost $4 billion – of the optical transceiver market by 2025, up from just a few per cent in 2016.

The transceivers are expected to be used mostly for intra-data centre communication, according to Yole, with the strongest demand being for 400G (400 Gigabits per second), and 200G acting as an intermediate step between 100G and 400G.

IEEE forms 802.11 Light Communications Study Group

The IEEE has formed the IEEE 802.11 Light Communications Study Group to work towards standards for light-based wireless local area networks (LANs) or Li-Fi as it is often known.

The new study group will directly engage with manufacturers, operators and end users in consensus building efforts and to create a Project Authorization Request (PAR) towards developing a global wireless local area network light communications standard.

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,

PHIX Photonics Assembly targets automated manufacturing

Start-up PHIX Photonics Assembly has raised a first round of investment from Dutch regional development agency Oost NL to build and develop a facility for volume production of photonic integrated circuit (PIC) modules for datacom, telecom and medical applications.
