Goals: Goals Examine the possibility to use standard 10G Ethernet LAN equipment for long-haul WAN transmission Using DAREnet’s 250km SMF link between Odense and Lyngby If possible find a setup that has a BER below 1E-12 which is the 802.3ae objective Use standard NIC’s and aggregating switch's to verify link with real Ethernet traffic Measure the setup’s power penalty DAREnet fiber in Denmark: DAREnet fiber in Denmark The 252 km of standard SMF dark fiber between Odense and Lyngby Includes three points for possible amplification, filtering etc. in Nyborg, Næstved and Taastrup Equipment: Equipment BATM T6 switch Including 10G Uplink module developed at CERN as part of ESTA Optillion TOP 5010-SC Xenpak transceiver 1550 nm optics with maximum reach of 40 km Includes IEEE802.3-2000 PMD BIST capability for BER measurements Optical amp’s and filters COM lab setup: COM lab setup Field tests - 1: Field tests - 1 Setup using pre-amp at receiver 4 amp’s in total per link 3 x 80 km DCF (Dispersion Compensating Fiber) Achieved BER andlt;1E-15 ! Limited by time shortage BER curves: BER curves Field tests - 2: Field tests - 2 Setup without using pre-amp at receiver 3 amp’s in total per link 3 x 80 km DCF Achieved BER andlt;1E-12 Shortage of time limited the experiments on this setup, BER could likely be improved Picture - Lyngby: Picture - Lyngby Xenpak Amp’s DCF PC Filter and attenuator Picture – Næstved and Odense: Picture – Næstved and Odense Conclusion: Conclusion Successfully used standard 10G Ethernet LAN equipment to transmit over 250km of SMF dark fiber (including optical amplification and DCF) Setup meets 802.3ae objective with a BER of 1E-12, best result is below 1E-15 Transmitted full-duplex 8 Gb/s real Ethernet traffic using 16 x 1 Gb/s NIC’s and aggregating switch's Measured setup power penalty at 1E-12 to be 2.5 dB Conclusion – cond.: Conclusion – cond. The successful results prove the possibility to use low-priced Ethernet LAN equipment for long-haul connections Future work and use: Future work and use Initial tests show the possibility to extend the reach even further Experiments could for example make use of the dark fibers continuing to Århus and Aalborg A 10 Gb/s link between SDU in Odense and DTU in Lyngby could for example be valuable as a GRID-to-GRID connection Questions?: Questions? Back-to-back sensitivity measurement: Back-to-back sensitivity measurement Used to determine the power penalty for the demonstrated setup You do not have the permission to view this presentation.
