Metro 100G and the coherent brick wall
18 February 2015

By Dr. Maxim Kuschnerov

The future never works out quite how you planned. After introducing 100G coherent technology into core and submarine networks, product design engineers now lust for a progression of proprietary coherent interfaces for the metro sector, enabled by falling component costs and higher-order modulation schemes that decrease the cost per bit of the physical interfaces.

Game on for fibre to the home

Playing games is not just a bit of fun; it is also big business; and it illustrates the importance of fibre to the home, according to Nadia Babaali

Top trends from ECOC 2014
23 October 2014

By Giacomo Losio, head of technology at ProLabs

ECOC 2014, the largest European optical communication conference, was a fascinating show. We saw myriad demonstrations of compact 100G devices in QSFP+ and CFP4 form factor, as well as multi-vendor interoperability of optical links where these two form factors are used. 100G client interfaces have reached a point where they can really enable design of dense systems.

Changing the playing field for data centre networks with SDN
09 September 2014

By Stu Benington, vice president of cloud and SDN business unit, Coriant

The evolving connectivity needs of both businesses and consumers are piling the pressure on service providers on a daily basis. Traditional business models are being exposed as outdated, while the limitations of traditional static transport architectures are being challenged.

Aurora2 helps researchers create future internet
26 August 2014

Michelle Pauli, a writer for JISC, examines a dark fibre project that will enable researchers to explore the future internet

How can researchers do the very necessary work of experimenting with a future internet and its technologies without breaking the internet we already have?

'Dark fibre' is the key, and UK researchers now have access to a whole lot more of it, thanks to the arrival of Aurora2, the National Dark Fibre Infrastructure Service (NDFIS).

Achieving carrier-grade software defined networks
18 August 2014

By Geoff Bennett, of Infinera

Writing anything about software defined networking (SDN) is guaranteed to get attention these days.  It’s a hot topic – not least because it really does offer a way to remove the domination of the Ethernet switch and core router markets by the established players and open up new possibilities for network functions virtualisation for network operators.
