I got a bunch of fs.com stuff and purchased a pac of 1309nm TX 1295nm RX version for upgrading the ethernet network from 10G to 50G. There are no technical issues with this product. For that I want to give 5 stars. I will continue to buy components from FS.com next time.

Second time ordering from fs.com. Easy to hook cables in and seems extremely stable. Asked some questions of the item and they responded very quickly. Anyway, I am very content with this purchase.
