CEO / World-Connect Sàrl

As an IT company specializing in the installation of network equipment, we've found FLEXBOX by FLEXOPTIX to be an invaluable tool. Its versatility across various transceivers and user-friendly interface has made our job easier and more efficient.
One of the most impressive aspects of FLEXBOX is the reusability of the transceivers. This feature allows us to reconfigure and reuse the transceivers as needed, offering unprecedented flexibility and cost savings.
The performance is robust, and FLEXBOX has not only saved us time but also provided a cost-effective solution without sacrificing quality.
In summary, FLEXBOX by FLEXOPTIX is a must-have tool for anyone in the networking field. We wholeheartedly recommend it and give it a five-star rating.

FLEXOPTIX have saved us from the misery and disappointment of searching in vain through our box of old, single-vendor transceivers when we need to connect up a device, only to find we don’t have a compatible module. Having the FLEXBOX and programmable transceivers in our toolbox means we’ve always got the right transceiver for any device.  The icing on the cake is the mobility pack which allows you to program any transceivers, anywhere, any time, with just a mobile phone and the FLEXBOX .  Absolutely brilliant and couldn't ask for more.

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.

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!

The flashing is very quick and you can configure it to flash multiple devices in a row. Definitely well worth it.

FLEXBOX makes it easier than ever to manage your optics hardware! From unboxing to a configured module in a minute! Great product.

I had the chance to flash my first transceiver with the FLEXBOX and also navigate through the different tools on the Windows App. I must say that I’m impressed by the flexibility and available features provided by this app and the FLEXBOX. I flashed a 1G LX optic to be compatible with a HP switch in production (Aruba Networks(ex. HP Network) / J4858A) and the switch immediately recognized the plug freshly configured. I can know count on my FLEXBOX for the future transceivers I’ll need to install/replace. Also, the optic measurement is a very good feature.

Senior System Engineer / Netica SRL

Working with a lot of different vendor and devices, it is always a problem to find the compatible transceiver from different distributors and especially to ensure that it is really compatible. I have found FLEXOPTIX, and the FLEXBOX and I must say that this is awesome! We can now simply buy generic transceivers and program them with the FLEXBOX and the FLEXOPTIX App. The application is fantastic and very easy to use! This makes us save a lot of time and no more concern about the compatibility.

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!

Michal Szarecki
IT Engineer / PM IT SOLUTIONS

I wanted to take a moment to provide some feedback regarding the on-site programming capabilities of your FLEXOPTIX product. I must say that being able to program SFPs on-site according to our specific requirements has been an incredibly valuable feature for our network infrastructure. The convenience and efficiency it offers have exceeded our expectations.
One of the standout benefits we have experienced is the rapid deployment it enables. Being able to respond quickly to changing network needs without having to wait for orders from different vendors has significantly reduced our deployment time. This has improved our operational efficiency and allowed us to be more agile in meeting our organization's evolving demands.
Moreover, the cost savings we have achieved through on-site programming have been remarkable. By eliminating the need to order pre-configured SFPs from various vendors, we have saved on shipping costs, streamlined our inventory management, and bypassed vendor-specific pricing structures. This flexibility has positively impacted our budgeting and overall equipment expenses.
This is simply a brilliant idea and product! Thank you!

Senior Network Consultant / CDMA Services Ltd

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!

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.
