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!"

  Jeffrey Bosma

  XS News , Sr. System & Network Engineer
• "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
• "Your FLEXBOX rocks. On our Linux workstations we can easily change the vendor and thus save costs. In addition, we are also convinced by the product quality, the support and the handling of the order. Thank you!"

  Managing director, croit GmbH
• "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!"
