What Customers say

• "Before we knew FLEXOPTIX, we always stocked various types of transceivers from different brands. Now, several years later, we have completely switched to FLEXOPTIX's universal transceivers since we can simply brand these ourselves using the FLEXBOX. Along with their broad product range and very fast shipping, they are an awesome company to deal with!"

• "We will now be able to source all our SFPs from a single vendor without having to worry about the configuration. That translates to peace of mind and huge flexibility. Well done guys!"

  CTO, Neocarrier Communications
• "For years we struggled with hundreds of transceivers from different vendors but this is finally over! With FLEXBOX we can easily reconfigure our transceivers which in the end saves a lot of time and money."

  Director Infrastructure Services, Avira Operations GmbH & Co.KG
• "The FLEXBOX was easy to set up and use, and the programmable transceivers worked seamlessly in several different brand devices. This will make our spares much easier to manage."
