If you want to save money...
These two Digitus SFPs with universal firmware will most likely also do for a fraction of the price (~25%) of the FlexOptix (for Anna-Lisa) for €98.
These two products from Digitus only differ in terms of operating temperatures. I would take the more robust as it is not much more expensive.

In terms of SFP selection you have to look for two things:
- firmware versions which indicate most compatibility to different vendors. Some SFPs have special firmware. Data Center customers e.g. needs different SFP/SFP+ for Cisco and Brocade switches ...
- price, in this area you pay sometimes a lot if the SFP is vendor certified (Cisco, HP). Prices over €1000 up to €5000 are not unusual. Many customers, even Data Center Customers, buy 3rd party as they regard it as unnecessary voodoo and in a datacenter you have redundancies for important connections anyway
Simply try it out .. like in many fields nowadays you need to look and check.
EDIT: Or save time and take the Direct Out product which is manufactured from FlexOptix (Darmstadt, DE), which you can regard now as preapproved by Matthias.

It looks that this german brand concentrates on delivering products with universal firmware that is most compatible to many products.
