OFC/NFOEC 2013 product round-up - Part 2

 Second and final part

• Custom add/drop integrated platform and a dual 1x20 WSS module
• Coherent receiver with integrated variable optical attenuator
• 100/200 Gigabit coherent CFP and 100 Gigabit CFP2 roadmaps     
• Mid-board parallel optics - from 150 to over 600 Gigabit.
• 10 Gigabit EPON triplexer 

Add/drop platform and wavelength-selective switches

Oclaro announced an add/drop routing platform for next-generation reconfigurable optical add/drop multiplexers (ROADMs). The platform, which supports colourless, directionless, contentionless (CDC) and flexible grid ROADMs, can be tailored to a system vendor's requirements and includes such functions as cross-connect switching, arrayed amplifiers and optical channel monitors.

"If we make the whole thing [add/drop platform], we can integrate in a much better way"

Cisco Systems' 100 Gigabit spans metro to ultra long-haul

Cisco Systems has demonstrated 100 Gigabit transmission over a 3,000km span. The coherent-based system uses a single carrier in a 50GHz channel to transmit at 100 Gigabit-per-second (Gbps). According to Cisco, no Raman amplification or signal regeneration is needed to achieve the 3,000km reach.

Feature: Beyond 100G - Part 2

"The days of a single modulation scheme on a part are probably going to come to an end in the next two to three years"

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"
