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"

Boosting the 100 Gigabit addressable market

Alcatel-Lucent has enhanced the optical performance of its 100 Gigabit technology with the launch of its extended reach (100G XR) line card. Extending the reach of 100 Gigabit systems helps makes the technology more attractive when compared to existing 40 Gigabit optical transport. 

 

"We have built some rather large [data centre to data centre] networks with spans larger that 1,000km in totality"  

Sam Bucci, Alcatel-Lucent
