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.

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.

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).

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.
What is SDN?

Now that the dust has settled after Next Generation Optical Networking 2014, Tim Gillett solicits the opinions of exhibitors and delegates

By any measure, it appears that the Next Generation Optical Networking show, held last month in June, was a huge success.

Mike Jones, vice-president of MicroCare, describes the use of fluids other than alcohol for cleaning fibre optic connectors

During the 1970s, Bell Labs was busy perfecting the technologies to commercialise fibre optic communications. They could see a time when all the copper wire in the world could not handle the volume of data that people would want to send over phone lines.

With most of the industry focusing on fibre and high-bandwidth microwave systems, Max Penfold, Sales Manager at UTEL, reveals why copper’s new secret weapon could stunt fibre’s growth.



Cost and compatibility can make a compelling case for pushing 100Gb/s bandwidth over a single optical channel, both as individual links and supporting 400Gb/s Ethernet, finds Andy Extance

Robin Mersh takes a look at how the industry is creating next-generation optical access fit for 5G


Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov and Dr Yin Wang
