What customers say

Working with the FLEXOPTIX Transceivers and FLEXBOX is not only uncomplicated but offers us the possibility of working with many vendor types to support the different campus networks. Thanks guys - awesome work.
Brian Masiga Network Engineer, Research and Education Network for Uganda
On more than one occasion the flexbox significantly saved time for me by not having to scrub a deployment session but simply reconfigure a transceiver and carry on. This alone is a good reason that secures the flexbox a non-negotiable place in my datacenter-go-bag. However what really sets flexoptix apart is not them solving an irritating problem we all know. No. It is their vast inventory and know-how paired with impeccable QA. If I have a need for transceivers it is my single go-to source for procurement. They have exactly what I need in stock even before I know I need it, and when I need it, I can trust the order is in my hands in no time. Every single time. I can configure and deploy without doubt and without delay. It is rare to find such a valuable and dependable partner that reliably takes away a whole set of problems while offering decent pricing and a customer support that is above reproach.

Everything is build for and runs in the cloud today, the Aviatrix Multicloud solution as well. Still, we have customers asking for a highperformance encryption from “their” premises to the cloud and this is where our CloudN appliances come into play. If customers ask us to support the installation of our appliances, we’ll do everything we can to help. And then it’s good to know that if you sneak into a datacenter, you can rely on FLEXOPTIX to even fulfil that connection(s) that are terminating on a device that was missing or has changed in the architecture you discussed before. Thanks for the brilliant service!

The flexbox has been an amazing tool for our Equinix AM5 deployments, we have used many brands previously however the flexbox was superior right from the start, especially when working in the datacenter and not needing to hold my laptop in my hand but my phone, which is just amazing for rapid deployments.

Looking forward to keep using the flexbox in the future! :)
