Hi I have guaranteed authentic Cisco Originals through a Partner for $125.00. All I have currently listed on amazon are compatible transceivers. The Cisco Original (QTY50) come with verification Certificates of Authenticity.

Hi, Are these Cisco OEM genuine SFPs or a 3rd party compatible SFPs?

Cisco Originale e riconosciuto come tale.

Semplicemente perfetto. Originale e riconosciuto come tale anche dagli switch di ultima generazione. Istallato in un C1300-MGP-8P molto particolare nel riconoscere gli switch SR (funzionava con compatibili SX ma assolutamente no con gli SR) ed ha funzionato senza problemi. 850 nanometri LC.
