What Customers say

• "Using FLEXBOX we have been able to deliver high quality optical adapter product range in a mixed brand environment, with the maximum flexibility in managing logistic and stock costs. It is a definitely a tool that every professional should use."

  Laert Klemo

  CTO, Eagle Security System
• "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!"

• "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!"

  Michael Nicolaou

  Senior Network Consultant, CDMA Services Ltd
• "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"
