2020 vision
Wednesday, May 30, 2012 at 9:20AM In a panel discussion at the recent Level123 Terabit Optical and Data Networking conference, Kim Roberts, senior director coherent systems at Ciena, shared his thoughts about the future of optical transmission.
Final part : Optical transmission in 2020
"Four hundred Gigabit and one Terabit are not going to start in long-haul"

Optical transmission's era of rapid capacity growth
Wednesday, May 30, 2012 at 7:39AM Kim Roberts, senior director coherent systems at Ciena, moves from theory to practice with a discussion of practical optical transmission systems supporting 100Gbps, and in future, 400 Gigabit and 1 Terabit line rates. This discussion is based on a talk Roberts gave at the Layer123's Terabit Optical and Data Networking conference held in Cannes recently.
Part 2: Commercial systems
The industry is experiencing a period of rapid growth in optical transmission capacity. The years 1995 till 2006 were marked by a gradual increase in system capacity with the move to 10 Gigabit-per-second (Gbps) wavelengths. But the pace picked up with the advent of first 40Gbps direct detection and then coherent transmission, as shown by the red curve in the chart.

The capacity limits facing optical networking
Tuesday, May 15, 2012 at 8:45AM Ever wondered just how close systems vendors are in approaching the limits of fibre capacity in optical networks? Kim Roberts, senior director coherent systems at Ciena, adds some mathematical rigour with his explanation of Shannon's bound, from a workshop he gave at the recent Layer123's Terabit Optical and Data Networking conference held in Cannes.

The post-100 Gigabit era
Thursday, March 8, 2012 at 6:37PM Feature: Beyond 100G - Part 4
The latest coherent ASICs from Ciena and Alcatel-Lucent coupled with announcements from Cisco and Huawei highlight where the industry is heading with regard high-speed optical transport. But the announcements also raise questions too.

Ciena: Changing bandwidth on the fly
Friday, March 2, 2012 at 4:00PM 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
Friday, December 9, 2011 at 8:06AM 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
