AT&T and Colt develop API for SDN-to-SDN interoperability

AT&T and Colt Technology Services have developed an application programming interface (API) that lets SDN architectures from different network service providers work together, and used it to integrate the on-demand capabilities of their respective networks.

The partners claim that this is the first successful trial to show software-defined network (SDN) interoperability.

AT&T to trial 400 Gigabit Ethernet services in 2017

AT&T intends to be the first in the industry to demonstrate 400 Gigabit Ethernet services across its production network, and will launch trials for business customers in early 2017.

The US service provider reported that data traffic on its network grew more than 150,000 per cent between 2007 and 2015, and continues to increase. The introduction of 400GbE is a natural progression, the company says.

Openreach and Huawei combine PON technologies to reach 52.5G speeds

Openreach, BT’s local network business, and Huawei, claim to have become the first companies in Europe to show how combining multiple access technologies on the same fibre could super-charge broadband speeds for businesses and consumers in the future.

The companies showed coexistence of 40Gb/s NG-PON2, 10Gb/s XGS-PON and 2.5Gb/s GPON technologies on the same fibre, giving an aggregate capacity of 52.5Gb/s on Openreach’s network.

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.
