We installed twenty of these 1310nm 10km SFP modules across a campus fiber network replacing aging optics. Every unit came online immediately and DOM statistics matched our expectations. Power levels stayed consistent after several days of continuous traffic. Definitely a dependable option for enterprise Gigabit Ethernet. ^_^
