2 Fibre sharing Field Trial Background GÉANT Telia Sonera fibre will not be renewed. Looking for cost saving solution. Field trial has been approved Field Trial Will test if GÉANT can make use of SURFnet s dark fibre to carry GÉANT DWDM trunks. Will be carried out on the SURFnet system Amsterdam-Hamburg line system Objectives test the engineering feasibility SURFnet sharing their fibre with GÉANT understand the costs of operating such a solution understand the operational model of such a solution Partners The GÉANT Association will lead and SURFnet be a partner in the field trial Infinera will loan GÉANT the cards necessary for the field trial for a period of 60 days 2

3 Challenge 1: Matching Infinera and Ciena channel plans The CMB8 channel muxes used result in guard bands of two 50GHz channels between each of the 9 groups of 8 channels to form a total of 88 channels with two of these unavailable to use (shaded dark grey) Infinera channels 3 and 8 overlap with guard-bands so can not be used. Because of these guard bands and CMB8 only 400G possible in the blue spectrum: 3 x 100G and 2 x 50G. For the field trial CMB8 channel muxes can be used. A better long-term solution is to use a single 44 channel Ciena Mux (CMB44) or WSS which will remove the guard bands 3

4 Challenge 2: 10 Wavelengths on one fibre Infinera Photonic Integrated Circuit (PIC) has an integrated AWG which multiplexes 10 x 50Gbps onto a single fibre Connecting direct into Ciena WSS is not a supported configuration. Field trial will overcome this by splitting out one 50Gbps wave per patch Requires an AWG and an amplifier to compensate for losses. 4

5 Field trial wavelength selection Two waves: nm, nm One of the Infinera wavelengths is 50 GHz and the other is 150GHz away from a Ciena 100G PM-QPSK This allows us to check the impact of adjacent waves.

Without the carrier, the WSS seemingly won t work. Hence if a 3 rd party connects to a WSS port, it won t acknowledge what is coming in. 8

11 Production phase Objectives: At the end of the field trial the loan optical components will be returned to Infinera. At this point it is proposed to re-engineer the system to use alien waves as a production solution. The aim is to re-use as many existing components as possible. The system should support up to G at the lowest engineering cost. Robust operational model is needed Two options considered: Use AWG to separate out each wave onto a separate fibre (as in field trial) Use WSS as a more flexible solution 11
