Given that the term web-scale was coined barely two years ago, it is surprising how quickly it has come to dominate the conversation in the optical networking industry. The requirements of web-scale operators like Facebook, Google and Microsoft are increasingly front and centre at events like OFC 2015, which was held in Los Angeles, California, in March.
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
