This is the "failure" of us (the business) choosing QSFP as the de-factor formfactor for 100G, there is not power in that cage to make 10km+ optics in an easy way. If we would have pushed for CFP4 as the "last" formfactor in 100G land we would be much better off. The options you have to choose

Hi What options are available for 40G QSFP+ and 100G QSFP28 for 10+ km links? I see a lot of switches offered with QSFP+ and QSFP28. But I do not seem to find the necessary optics to build the links I want. For example, take a look at the options available at Fiberstore:
