    Worked instantly and perfectly. Cost was unexplainably low. Delivered from China in less than weeks for less than $2 total cost??? The seller must be taking a loss, but I am not complaining. I couldn’t mail this thing across town this cheaply. It makes no sense, but I’m a happy customer.

    Awesome.

    Had major issues with my new network, took a chance and purchased these as a last resort after spending several late nights going through my hardware, drivers, settings and cabling trying to figure out why my computers wouldn't communicate over the optical connections. I had some ssporadic communication comming and going but it was highly unstable and switching my tranceivers between cables, network cards and computers didn't help. These receivers was delivered a few days later, I replaced the ones I had with these and my network instantly came to life. I have now ordered more of these to keep for spares and future expansions.

    Great 10gb optics for best price!

    Excellent 10gb mm sfp's and an even better price! They work well in my unifi and brocade equipment. I did have an issue trying to use one with an intel x520, ended up using the intel optics that came with the card.

    Product arrived in a pair of static shielded bag, promptly. worked right out. I will point out that these are not 10km SFP+ connectors. Manufacturer

    Product arrived in a pair of static shielded bag, promptly. worked right out. I will point out that these are not 10km SFP+ connectors. Manufacturer states max of 400m. Works perfectly with runs of 2-8m, which is my use case. Will buy again when I need to expand my 10 GB network.

    Fraction of the price for the same apparent quality

    Installed them yesterday with Mellanox ConnectX-3 and ConnectX-4 cards and a Ubiquiti XS-16 10G switch. 10G connection appears to be solid and they're actually running cooler than the Ubiquiti SPF+ that I bought to compare. Paid $6.50 each which is less than a third of the price of the Ubiquiti new. Great product at a great price.

    Compatible with Emulex BE3 10GB cards.

    Buying these transceivers was a shot in a dark, as I wasn’t 100% sure they would work with the Emulex 10GB card. I popped them in, put the cables in and card recognized them immediately. Came professionally packaged with great care. Will definitely buy again.
