Design and OAM&P aspects of a DWDM system equipped with a 40Gb/s PM-QPSK alien wavelength and adjacent 10Gb/s channels Lars Lange Bjørn, NORDUnet Roeland Nuijts, SURFnet Martin Nordal Petersen, DTU Fotonik Anna Vasileva Manolova, DTU Fotonik Terena Networking Conference 2011 16 - 19 May, Prague, Czech Republic

Outline History Design VPI off-line simulations Experimental results OAM&P Costs considerations Conclusion

History April 2009: SURFnet fosters the idea of deploying an alien wavelength. SURFnet purchases and install additional needed hardware Ready to go – September 2009 November 2009: Hero experiment presented at SC, Portland Oregon. Ability of both network was tested Shortcomings identified Operated in un-optimized conditions; BER < 3,0 10-16 June 2010: TNC 2010, Vilnius, Lithuania. Simulations in Ciena Optical Modeller Optimized condition BER < 10-17 May 2011: TNC 2011, Prague, Czech Republic. Whats new?

VPI: Assumptions and Method Noise Figure (AMP) = 5 OSNR at REC = 20 PMD: 0.05x10-12 s/m½ Nonlinearity index parameter (transmission fiber): 2.4x10-20 m2/W Nonlinearity index parameter (DCM fiber): 3.0x10-20 m2/W Method Monte Carlo approach: 50.000 bits per data point Simulation time usage: With nonlinearities ~ 3-4 hours per data point. Without nonlinearities ~ 15 minutes.

VPI Results: 10G variation w. constant 40G XPM Lack of SPM?

VPI Results: 10G off / 40G high power Strong SPM

VPI results: 40G variation w. constant 10G XPM SPM

Experimental results: 50GHz spacing 10G power (dBm) Operational window very tight

Experimental results: 100GHz spacing 10G power (dBm)

Experimental results: 150GHz spacing 10G power (dBm)

Experimental results: 50HGz to 150GHz @ 10G = -20,7 dBm The pre-FEC BER is below 10-3 unless spacing is above 100GHz The Alcatel-Lucent design guide specifies 10G = -17,2 in order to maintain guarantied performance according to traffic matrix!

OAM&P - standardization ITU Standardization G.698.1: Multichannel DWDM applications with single-channel optical interfaces G.698.2: Amplified multichannel dense wavelength division multiplexing applications with single channel optical interfaces Scope & Info To provide optical interface specifications towards the realization of transversely compatible dense wavelength division multiplexing (DWDM) systems primarily intended for metro applications Applicable for 2,5G and 10G @ 100GHz / 50GHz spacing

OAM&P - issues Consequence NREN ISSUES No transverse compatibility for newer LH modulation schemes. No standardization targets LH/ULH applications No standardization targets OTS/OMS interworking NREN TARGETS Full optical transparency Bitrate Modulation format Spacing Full optical control Power Spectrum Admission

Cost considerations: 200G Amsterdam - Copenhagen 6 min/XFP 12 min/MUX 30 min/linecard 15 min/wave config 20/30 hours travel AW/REG Guard band neglected AW and native signals can co-exists (Joint design rules) Alarm and Management integration is possible

Conclusion VPI simulation platform for alien wavelength evaluation conforms qualitatively with experimental results 40G PM-QPSK together with 10G NRZ shows large BER variations for varying power and guard band size OAM&P is adequate for this mix of products, few steps are needed for “normal operation” Costs is for this mix of products in favour of the AW approach
