  16. 16. WDM NICE ROUGH TRAVEL GUIDE: AT THE 100G CAFE 04/07/2009 So here we are at the must-attend 100G showcase, with no fewer than 7 vendors jostling for position on the stage in front of a baying crowd*.  The only qualification?  To have a published field trial with an operator.  However, one does not! I leave as an exercise for the alert reader to discover which! I'll try to encapsulate each trial/vendor in a few highlights, which will doubtless cause trouble for omitting some important aspect - there's no substitute for being here!  As the 100G alphabet soup is cooked, I suspect the session will run late. Alcatel-Lucent. 1st 100G trial with Verizon 16/11/07.  500km Tampa-Miami. DQPSK-NRZ/RZ modulation also with 10G channels.  Has published 13 R&D papers since 2005.  Conclusion: 100G PDM-QPSK (25 Gbaud) with coherent detection and digital post-processing, also compatible with 10G NRZ and 40G. Ciena.  100G trial with Caltech over 1500km.  Agrees with Alcatel-Lucent on system technology - ADC plus DSP ASICs also Photonic Integration.  30-50% p.a. traffic growth means capacity exhaust, even 40G is insufficient in 2012.  There will be much secret sauce from different vendors. Cisco.  1st 100GbE 802.3ba-based router demo with Comcast 6/08.  Key requirement is compatibility with 10G links @ 50GHz.  Conclusion: PM-QPSK modulation (25Gbaud).  Sees 100G in routers for IPoWDM architectures, but also transponders.  Vision shows 200G, 400G, 1T, CO-OFDM, software-defined optics. Ericsson.  112G trial with DTAG over 633km including 4x ROADM.  PM-RZ-DQPSK modulation with fast LiNbO3 polarization tracking plus 10G and 40G neighbouring channels.  Conclusion: PM RZ-DQPSK @ 50GHz needing no ADCs or DSP since polarization tracker is used for PMD tolerance.  Investigating OFDM, SCM, nQAM. 23 July 2009
  17. 17. WDM NICE ROUGH TRAVEL GUIDE: AT THE 100G CAFE Huawei.  Several options available.  OPFDM-DQPSK or OPDM-DQPSK - no ADC/DSP is needed so cost-effective.  ePDM-DQPSK provides best performance, >1,000km but is more complex.  Market timing is critical, as is ASIC complexity and availability.  Sees a 5 year delay between 40G and 100G deployments. Nokia Siemens.  107G trial with AT&T in 2006, 2x 80km direct optical. 1st CP-QPSK in 2007.  111G trial with Verizon in 2008, 1040km and mixed 100G, 10G and 40G channels.  Believes that coherent CP-DQPSK is the way forward, hero experiments are now finished, and need to make real commercial products. Nortel.  100G trial with Comcast 3/08, 335km link including ROADM.  Many network demos 2008-09, including Verizon 73km link that could not carry standard 10G.  Conclusion: coherent FDM-DP-QPSK (14Gbaud) @ 50GHz.  Vision that coherent plus WDM gives next big jump in fibre capacity. I have the feeling of an industry - at least most of the vendor side - in a hurry, pushed by an invidious mix of public demand from a few high-profile carriers, the prospect of competitive IEEE interfaces, intense vendor competition plus a driving technological rivalry to scale the 100G mountain. I remain most concerned about gaining sufficient economy of scale, but despite appearances, the industry is largely converged on DP-QPSK with coherent detection.  And whilst vendors may be reluctant to highlight it, the OIF's MSA functional standardisation is a critical first step towards economy. 23 July 2009

  21. 21. Orange UK: Infrastructure fixed - mobile convergence is a reality The optical layer offers a very cost effective solution for such infrastructure FMC Study network traffic flows before selecting future network architecture and/or implementing capacity upgrades The combination of Ethernet optimised PE routers, high speed core P routers and optimised optical infrastructure ensure the tools are available for cost-optimised core transport network evolution 23 July 2009
