It’s great to find this XFP module in this website with such a cheap price. The original brand module is too expensive. We also asked many other vendors, and many of them can provide this module but with really high price and we need to wait a long time before we receive the module. Then we find this website offering this module with same day shipping service. We ordered directly after the sales told us not to worry about the quality and compatibly of this module. Now we have already received the modules. Hope it can work well in the future.
