To cope with society’s unrelenting desire for on-demand content and subsequent traffic growth in data centres, optical transceivers need to deliver increased speed, bandwidth and density – and all at a lower cost!

The statistics behind the information explosion are truly astronomical. More data has been created in the last two years than in the entire history of the human race.

With so much information being created, data centre operators need high-capacity optical communication networks to transfer data rapidly and efficiently around their facilities. Today’s 100 Gb/s data rates have sustained the data deluge up to now, but will soon need to be trumped by higher transmission speeds if traffic growth is to be maintained.

200Gb/s and 400 Gb/s transceivers are seen as the next new standards, and researchers are working feverishly on ideas to squeeze next-generation performance out of current-generation systems. Similarly, manufacturers are coming up with various new and innovative single mode transceivers capable of delivering increased speed, bandwidth and density. However, innovation is expensive: the elephant in the room remains cost.
