As usual, we are extremely satisfied with the transceiver module received from FS. They are well-packaged, perform excellently, and have a sleek appearance.

Top preise, Top Quality!

Worked great connecting a Cisco Catalyst 3850 and 3650 on their 10gb ports at about 11 miles apart.

Die Modulverpackung sieht sehr sorgfältig aus und ist wirklich gut zu verwenden. Besuchen Sie sie also beim nächsten Mal wieder!

Got the 10GBASE-ER SFP+ transceivers, 5dB fiber optic attenuator, and LC duplex OS2 single-mode fiber optic patch cables. Really compact gadgets that paired very well.

The web site makes it easy to find the correct items and once ordered they are sent promptly with emailed advice along the way. My experience was a very positive one.

Als optisches Modul eines Drittanbieters ist die Kompatibilität in Ordnung, und der Preis beträgt nur etwa ein Drittel des Originals, was recht kostengünstig ist.

I bought serveral 10G SFP+ transceivers here for my Cisco switches. Thanks to my account manager, she reminded me that this transceiver is for 40km transmission, thus I need 5dB fixed attenuator as my connection is less than 20km. I bought some fixed attenuators along with the 10G SFP+, work like a charm.

Bought the S5800-8TF12S with L3 Routing. 100% pleased with the switch port config. The AM has recommended this 10GBASE-ER SFP+. Worked right out of the box. Great.

Wird für Unternehmen verwendet. Die Technologie sagt, dass die Qualität sehr gut ist.
