umm..are you sure your question is not about EIGRP?
OSPF has no concept of interface-delays.
The default reference bandwidth for OSPF is 100M
In your case if you set your reference bandwidth to 100000 your 100G links would have a link cost of 1, 10G - 10, 1G-100, 100M-1000 and 10M-10000
A vendor specific list would be a better place to ask.
