Customer feedback

Christian Seitz

"With the FLEXBOX we’re able to use our Transceivers universally in all kind of equipment and reduce the stock keeping significantly. Just awesome!"

Nikos Papandreou

"Now that I’m done configuring my equipment, I use FLEXBOX to impress associates. I’m an IT Hero just for the savings, not to mention the FLEXibility to stock one type for each adapter. Keep up the good work!"

Philipp Päper

"Einfacher geht es nicht! Die Programmierung der SFPs kann ohne Einweisung durch jeden IT-Mitarbeiter durchgeführt werden. Der für uns wichtigste Punkt ist aber, dass wir endlich nicht mehr für jeden Hersteller SFPs vorhalten müssen. Ein paar FLEXOPTIX-SFPs genügen."
