What Customers say

• "Have been using FLEXOPTIX transceivers for a few years now in a carrier/telecoms environment for various vendors and they've never disappointed me. After having the opportunity to be able to program them myself on demand, I've realized how many hours I could have saved until now with FLEXBOX! No large stocks, just a few generic SFPs in stock waiting to get programmed when needed. Awesome!"

  Senior Network Consultant, CDMA Services Ltd
• "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!"

• "When in possession of the Flexbox it becomes and indispensable tool in general, and also specifically in managing remote Mobile Base Stations fiber connectivity. Using the Flexbox either with PC or Smartphone is really plug and play with no annoying incompatibility issues at all. The Flexbox together with ease of order and superior delivery times makes it literally unnecessary for us having any significant SFP stock."

• "The SFP are exactly like promise on the web page, and the configuration tool is so amazing. I worked years with SFP and optical fiber and this tool is so great. It include a power meter an OTDR and allow to diagnose and configure the SFP for many vendors. It will help us in our research and also to manage our LAN. Thank you FLEXOPTIX"
