You need dark fibre for each remote shelf connection as well as for FC-VI port. This amounts to two optical pairs for each stack. As stacks should be mirrored, minimum that makes sense is 6 optical pairs between sites.

Stretch Metrocluster - How many dark fibres?
created by Willybobs27<https://communities.netapp.com/people/Willybobs27> in Data ONTAP - View the full discussion<https://communities.netapp.com/message/97679#97679>
I've looked at various bits of documentation and some suggest 2 dark fibre's, one for each fabric, whilst others show 4 dark fibre's one for each fabric and 2 for the FCVI cluster interconnects.
Which one is correct?
