Hello, it is my understanding that they are compatible. I did have some questions so I referred to Cyclone V Device Datasheet pages 16-18 regarding 1.5V PCML. Here is what I have found.

Transceiver (AC Coupled)Vod (max) = 1200mVVod (typ) = 660mV (my co-worker found this somewhere)

Vod (min) = 120mV (my co-worker found this somewhere)

Vocm = 0.65VReceiver (AC Coupled)

Vid (max) = 1600mVVid (typ) = 200mV(my co-worker found this somewhere)

Vid (min) = 700mV(my co-worker found this somewhere)

Vicm = 0.8V

I also contacted the vendor of the SFP which was very helpful.

You might consider contacting a Field Applications Engineer from Altera, must open a Service Ticket with Altera, ask you questions and also ask contact an FAE.

I think you will be okay.
