Nokia joins UK's pioneering smart city initiative in Bristol

Nokia has joined the Bristol Is Open initiative, becoming the first major telecoms vendor to participate in Bristol's unique living laboratory.

Bristol Is Open (BIO) encompasses the entire city, effectively transforming it into a dynamic test bed to explore how integrated technology can benefit citizens – from helping solve problems such as traffic congestion, air pollution, and assisted living for the elderly to trials of self-driving cars.

Nokia Bell Labs touts 65 terabit transoceanic transmission trial

Alcatel-Lucent Submarine Networks (ASN) and Nokia Bell Labs have achieved what they claim is a record transmission capacity of 65Tb/s over 6,600km of singlemode fibre.

An interesting point of comparison: the capacity of 65Tb/s is 13,000 times greater than the capacity that was available on the first undersea amplified transatlantic system installed in 1995.

Ixia and Viavi showcase 400 Gigabit Ethernet test system with FEC

Participants in the demo, from left to right: Thananya Baldwin and Jerry Pepper from Ixia, Paul Brooks from Viavi, and Sando Anoff from Finisar.

ECOC 2016 - Ixia and Viavi Solutions joined forces to show what they claim is the world’s first public interoperability demonstration of a test system running bi-directional 400 Gigabit Ethernet line rate traffic with RS-544 forward error correction (FEC) as currently defined in the IEEE 802.3bs draft standard.

Lumentum and Finisar show 100G SWDM4 transceiver interoperability at ECOC 2016

Lumentum and Finisar took part in what they claim is the industry's first interoperability demonstration of 100G SWDM4 optical transceivers at ECOC 2016 in Dusseldorf, Germany, this week.

A live data link ran between the Lumentum and Finisar booths with SWDM4 optical transceivers from the two manufacturers exchanging data via a traditional duplex multimode optical fibre. The QSFP28 modules are plugged into test systems provided by Anritsu and Viavi, recording error-free transmission, thus demonstrating the transceivers' ability to communicate with each other.

VPIphotonics and Luceda Photonics collaborate on tools for PIC simulation and layout

VPIphotonics and Luceda Photonics have teamed up to develop a method to automatically export photonic circuit designs from the VPIcomponentMaker Photonic Circuits design software into IPKISS.eda for layout design and mask generation.

The interface was developed at the request of customers, especially those involved in silicon photonics, according to the two companies.

Nokia Bell Labs, T-Labs and Technical University of Munich test drive novel modulation scheme

ECOC 2016 – Nokia Bell Labs, working with Deutsche Telekom T-Labs and the Technical University of Munich, has achieved terabit transmission capacity and unprecedented spectral efficiency in a network field trial using a new modulation technique, called probabilistic constellation shaping.

This research will help telecom operators and enterprises to further optimise the distance and capacity of their optical networks – by dynamically adjusting transmission rates to suit the channel conditions.

Infinera serves up Transport SDN with Xceed Software Suite

Infinera has unveiled the Xceed Software Suite, a portfolio of modular software components that can automate service provisioning in Infinera-based optical transport networks.

The suite comes in two main parts. The Xceed Multi-layer SDN Platform provides software-defined networking-based automation of control plane functions. The Xceed Applications are a set of starter ‘apps’ that enable service providers to immediately start using the new software to activate bandwidth and reconfigure network resources.

First light for Intel’s silicon photonics transceivers

On August 17 at the Intel Developer Forum in San Francisco, Intel announced that its silicon photonics platform is now in volume production and shipping in the form of 100G optical transceivers.

The announcement highlights the maturity of this technology, as demonstrated by the commercial availability of the first products, the company asserts.

Adtran develops tunable subscriber optics for NG-PON2

Optical access vendor Adtran announced the development of what it calls Subscriber Edge Tunable (SET) transceivers for next-generation passive optical networks at its annual analyst event held this week in its Huntsville, Alabama headquarters.
