Infinera waves on a Ciena light system Guy Roberts, GEANT Association Terena Architects workshop, 12 Nov 2014
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 • To test the engineering feasibility SURFnet sharing their fibre with GÉANT • To understand the costs of operating such a solution • To 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 Connect | Communicate | Collaborate
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 Connect | Communicate | Collaborate
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 Connect | Communicate | Collaborate
Field trial wavelength selection • Two waves: 1556.55nm, 1554.94nm • 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 Connect | Communicate | Collaborate

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 500G 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 Connect | Communicate | Collaborate
