FSP Qualifications
•

Providing a bit level transport on optical layer is not enough

•

ADVA has to understand the applications and the impacts of conversion
and distance transport

•

To verify our understanding and to make sure our customers get the full
support of their storage equipment vendors we run an extensive
qualification program

•
