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

Fibre sharing Field Trial


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


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.

Challenge 2: 10 Wavelengths on one fibre

• 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.

Some WSS implementations look for a carrier as a ‘keep alive’ for the WSS to operate. Without the carrier, the WSS seemingly won’t work. Hence if a 3rd party connects to a WSS port, it won’t acknowledge what is coming in.

Following cards fit into Infinera ATC-A chassis: • OFM-4 Optical multiplexer • AAM Amplifier module • PCM Power control module • AMM Management module • IQA Network operating system

AOLX-500 goes into the DTN-X GÉANT


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
