What customers say

FLEXOPTIX creates overall great and reliable products. We need optics for multiple vendors and with the FLEXBOX we are able to simplify our spare part handling. The best part of the FLEXBOX are the Linux drivers and therefore no need for any additional OS just for branding optics.
Dominik Grueber Hetzner Online GmbH / Network Administrations

Woa, i can get next day delivery for any vendor. That’s a game changer. Also thanks for making it a smartphone app, this fits my workflow well.

Arvid Picciani CEO / devguard GmbH

FLEXBOX made my life a lot easier, adapting to multiple hardware in a breeze. I used fiber/SFP, RJ45/SFP, RJ45-10G/SFP for an esports production with different hardware brands and all of them worked instantly.

Before being a FLEXOPTER I had a lot of trouble communicating with my infrastructure and acquisitions team because of the complexity of compatibility between different brands and models

now I can operate and adapt to each on site production.

Emilio Vargas Production Manager / Liga ACE esports
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.
