The uphill battle to keep pace with bandwidth demand

Relative traffic increase normalised to 2010 Source: IEEE

Optical component and system vendors will be increasingly challenged to meet the expected growth in bandwidth demand.

According to a recent comprehensive study by the IEEE (The IEEE 802.3 Industry Connections Ethernet Bandwidth Assessment report), bandwidth requirements are set to grow 10x by 2015 compared to demand in 2010, and a further 10x between 2015 and 2020. Meanwhile, the technical challenges are growing for the vendors developing optical transmission equipment and short-reach high-speed optical interfaces.

Ciena: Changing bandwidth on the fly

Ciena has announced its latest coherent chipset that will be the foundation for its future optical transmission offerings. The chipset, dubbed WaveLogic 3, will extend the performance of its 100 Gigabit links while introducing transmission flexibility that will trade capacity with reach.

Feature: Beyond 100 Gigabit - Part 1

"We are going to be deployed, [with WaveLogic 3] running live traffic in many customers’ networks by the end of the year"
