This module works perfect. I have 3 pairs of these and all of them work stable. My dark-fibers are longer than 10km but the link is stable even with attenuators. The lower optical power budget is approx. -17dBm. Im using one of the pairs over a 18km route, both modules are receiving -15dBm and they are working stable, without port flapping or interface errors. I will confidently purchase these modules again in case of need.
As a suggestion, I can recommend that Fiberstore produce a version of these to work over 4 wavelengts 1490-1550nm instead of 1270-1330nm. Thats very much required for operation over G.655 fibers.

at beginning 100% I'm not sure this stuff will working on my switch Dell Force10 S4810 since on datasheet mentioned for optic QSFP+ support for 850nm only and no 1310nm, after convinced by FS that they tested already with the same brand and type switch as what I have at they lab then we do the order.
Shipment is good, price is great and the spectacular one is....the stuff is working with properly, so far our network running without any interruption from this QSFP+. Very good job FS and keep it that way; thank you very much.
