GUEST VIEW: 100G makes inroads across ASEAN

Luigi Castelli | Oct. 14, 2013
If 2012 proved to be the peak year for 40G shipments worldwide, led by demand in Japan and China, this year is shaping up as a take off point for 100G optical networks.

Given the hyper growth in capacity expected within a decade, 100G will be a prerequisite to design and develop solutions able to scale beyond 100G without requiring significant additional investment in common parts or an optical transponder. Service providers dream of upgrading 100G to 400G with just a simple upgrade! Thanks to programmable ASICs and innovative DSP (digital signal processing) this might soon be possible.

Due to the combination of aggressive (and in sync) spending on 100G coherent in China (China Mobile and China Unicom) and countries like Japan and Korea, Asia Pacific was the region that spent the most on 100G in Q2 2013.

Early adopters of 100G are now looking to double capacity carried over a single channel (i.e. from 100G to 200G per each optical wavelength) as well as to test  solutions based on a "super channel" approach and capable of delivering 400G per each couple of adjacent wavelengths.

Imagine a device connected to a network operating at 200Gbps. Transferring 500+ DVDs (1,000+ hours of viewing time) would take less than one minute; downloading a 100GB Blu-ray disk would take 4 seconds. For some in Asia Pacific, that future is not so far off.
