      Just plugged these 10G BIDI SFP+ modules into our switches. Got solid connection, runs cool, and no issues over our 15km link. Great value for the performance. Definitely recommend if you need reliable 20km optics.

      Just got these 10G BIDI SFP+ modules to link two buildings in our campus. Setup was super easy—plugged them in and they linked right up. Even around 18km, the signal is strong and stable, no drops. Great price for a reliable 20km solution. Works perfectly for our point-to-point connection!
