Formerly a System & Network Engineer at the service of French Academic and Research Network and currently developing my own IT services business, I have been a strong advocate of FLEXOPTIX "one-SFP-fits-all" approach since 2015! Having purchased close to 1500 optics over the last few years for different kinds of projects (Metropolitan & Campus Networks, Datacenter, Nexans FTTO projects), I have always been completely satisfied with FLEXOPTIX products. I have had the opportunity to test several competing solutions and for me "FLEXBOX" is by far the most advanced in terms of functionality, ease of use and compatibility. Beyond the flawless technical aspects, the many human qualities of the different people I have had the opportunity to exchange with are a priceless advantage: sympathy, reactivity, impressive know-how, infallible logistics and after-sales services, FLEXOPTIX is a company you enjoy working with and you can trust one hundred percent. Thanks a lot guys!

Spending a few minutes of my time, first and foremost expressing how much I’m impressed by your friendliness, is the least I can do. Friendliness was followed by super-fast order processing and delivery. In a few words, unboxing and using your Flexbox is an utterly awesome experience. As in brilliant. Also saving us loads of time ordering optics. In addition to all of this – you deliver particular good build quality, too. You’ve got me impressed, thank you!

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.

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.

Our engineers spend a lot of time in data centers connecting switches and routers from different vendors. With the FLEXOPTIX service not only their task gets easier, also the back office doesn't have to have a broad range of optics from different vendors in stock anymore. The days that an engineer stand next to a router with an optic from the wrong vendor are over. With the FLEXOPTIX FLEXBOX the engineer simply reconfigures the optic, and that’s that. As an added benefit with the FLEXBOX there is no need to connect a new cross-connect to a device to see if it is connected on the other side. The measurement option that comes with the FLEXBOX are very handy!

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

We use “FLEXBOX” and “FLEXOPTIX” for a few years now. Since then life is much easier. And even saved me sometimes in the middle of the night. Need a special vendor or type, plug it in, program, and done. Very… but very occasionally a compatibility is not present in the system. Just drop a e-mail to support with your needs to get an immediate response from “JIRA – the flexoptix robot” and your compatibility is added to your FLEXBOX within 24 hours. Just awesome!!

Now that I’m done configuring my equipment, I use FLEXBOX to impress associates. I’m an IT Hero just for the savings, not to mention the FLEXibility to stock one type for each adapter. Keep up the good work!

Absolutely Flawless! Ultrafast delivery and real plug & play from start to finish. Now we're able to react on needs much quicker thanks to the FLEXBOX. Having Universal Transceiver on stock and instantly program them to customer's need is amazing.
Bronislav Robenek
Bronislav Robenek Network Architect, Cloud4com
Ordering and using FLEXOPTIX transceivers was far quicker than even getting a quote from traditional vendors. Using the FLEXBOX is super easy and fast - 5 minutes to get transceivers ready including unboxing and enjoying packaged marshmallows.
Klaus Degner

The FLEXBOX allows us to use 100MBit/s to multi-gigabit transceivers in our product for a wide range of customer needs. We can not solve them without this magic box!

The FLEXBOX is really a great tool. It allows me to quickly re-configure transceivers. Nice additional feature is the "Power Meter & Source" tool. It allows, without additional hardware, a quick check of optical transceivers, fiber cables, fiber connections etc.

Just wanted to express my giddy happiness at how fast your crack team of ninjas were able to get optics to my desk.

With the FLEXBOX we’re able to use our Transceivers universally in all kind of equipment and reduce the stock keeping significantly. Just awesome!
Using FLEXBOX and FLEXOPTIX transceivers mean for us Flexibility. We don’t use so much transceivers but we work with different brands each day. With a small amount in stock we can configure them with the right specifications for each use. Assuring it will perfectly fit the requirements of our equipments and costs are also reduced considerably. Setting up either the FLEXBOX and a transceiver on a computer or through the mobile app is just easy as 1,2,3. It tooks us less than 15 minutes between unboxing and using a transceiver. We really appreciate the mobile option so we can have the FLEXBOX in one hand, a transceiver in the other one and the phone with the app in the pocket for programming on the field. Thanks FLEXOPTIX for this really useful tool and for extending supported vendors in the future.
Christophe Mulkers CEO/CTO, Oufti Connections
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.
Michael Horn Telecommunications Infrastructure Security Professional
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!
Gerald Buchholz / Principal Solution Architect Aviatrix
After many years of using clumsy EEPROM programmers, soldering irons, hammers etc. to make SFP modules work properly, now FLEXBOX allows me to do the same thing in a fraction of time. I only hope my boss doesn't find out I have so much free time now!
Adil Demiri CTO, SGN d.o.o.
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
Veloci e impeccabili! Transceiver, cavi e accessori super affidabili. Uso FLEXOPTIX da 6 anni, nessun difetto, nessuna preoccupazione, tutto funziona, anche la prima ottica XFP installata ad Agosto 2015 ???? FLEXBOX è la "ciliegina sulla torta" del mood Flexoptix: completa la filiera "quotazione -> ordine -> configurazione -> consegna", consentendo ai clienti di essere al 100% autonomi, veloci ed impeccabili nell'acquisto dei dispositivi ottici. Leggere e configurare un'ottica è questione di secondi, il supporto multipiattaforma per una completa FLEXibilità...è uno tool indispensabile anche per la risoluzione dei problemi (misurazione della potenza ottica, analizzatore di distanza e molto altro). Insomma...Spacca!
Alessio Faticoni Senior System Engineer Sinapsi
The flashing is very quick and you can configure it to flash multiple devices in a row. Definitely well worth it.
Adam Montgomery Necto Inc
Definitely, FLEXOPTIX will be my optics supplier from today. The ability to compatibilize optics across multiple vendors is going to save us from many headaches. The FLEXBOX is a must for any company using optical network equipment.
Miguel Bérniz Chief Technical Officer, GibFibre Ltd
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!
Martin Verges Managing director, croit GmbH
Since we ordered a FLEXBOX, our life as definitly changed. There’s a before and an after FLEXBOX. So many vendors in the compatibility matrice, so easy way to configure the module! And the cables and accessories came also with quality.
Stéphane Gouron Directeur Agence Ouest, S-cube.
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
It's just a genius device. So easy to use and simple! I would recommend it to every network engineer. Plug-in the module, program and its ready for deployment!
David Schoefberger Schoefberger
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
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.
Terji Leitisstein Hansen RAN Manager, Vodafone FO
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
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!
Gregory Agerba CTO, Neocarrier Communications
Very easy to use and quick too. I particularly like the ability to use the same configuration on a number of transceivers just by ticking a box - a real time saver
Mike Dallaway Mira 2014 Limited
Extensive list of supported vendors. Your product is like a Swiss Army Knife that all Engineers should have!! Great Job and keep it up!
Fahad Dalwai Network Engineer, Abdulaziz Abdulmohsin Al-Rashed Sons Co. W.L.L.
In our test environment we use the optics over and over in many devices. Programming optics with the FLEXBOX is as easy as 1,2,3!
Erwin ter Hofstede CEO, EC-Hosting
FLEXBOX allows us to reduce the amount of spare transceivers we keep for our diverse hardware systems, thereby keeping overall cost low.
Sven Gebhardt Head of Platforms & Services, grandcentrix GmbH
The FLEXBOX was easy to set up and use, and the programmable transceivers worked seamlessly in several different brand devices. This will make our spares much easier to manage.
Shaun James Engineering Inspector, Tata Steel Strip Products UK
The FLEXBOX is the best thing since sliced bread!
