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!

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.

We use FS modules for years with different networking hardware. Amazing and very stable products without any issues. Preparing a big network project with several switch vendors it was time to do the next step and order a FS BOX. Now we can be much more flexible than before and the provided tools are fast, stable, easy to use and as stable as all other FS producs. All in all - highest recommendation!

About two months ago, we started to prepare for our new project. Then I contacted my AM to get some technical supports by providing our network diagram with detailed info. For our case, the distance between Site A and Site B is 15 km & Site B and Site C is 8 km. The tech support team offered us two alternative solutions based on our requirements (real-time monitoring). After discussing, we drafted a shopping list. They double-checked the list and advised that we should replace CWDM 40km modules by 80km ones. And they helped us to change the module types covering CWDM-SFP10G-1470, CWDM-SFP10G-1490, etc. It's worth mentioning that they even noted the color of the devices for aesthetics. Combined with professional and considerate, quite impressed.

We planned to buy several 10G CWDM optical transceivers for 50km link between Site A and Site B. I turned to FS without hesitation, my first choice always. These 10G CWDM SFP+ modules that support 10km to 80km over single mode fibers perfectly meet our demands. They have performed as expected with no issues so far. Fabulous!

According to the FS team’s suggestion, we used the 80km CWDM modules in our 8CH CWDM MUX. The whole negotiation with those guys were quickly and professionally. And we were delighted with the final 3dB optical margin over the whole link.

FS tech team recommended the product for our Nokia device, and figured out the optical budget for our 65km link. Their attention to detail and communication is 10/10.

We wanted to connect our Cisco switch with a CWDM Mux Demux nearly 80 kilometers away (less than 80 km). Just not sure whether the module we found could support the need. We consulted the FS AM, and then bought this one. It worked as described and there was no problem after using it for 20 days.

I wanted to realize the transmission of multiple 10G businesses on dual fiber through a WDM system. FS AM gave me a solution by using this 10G transceiver and a pair of matched 8CH CWDM Mux Demux. At first, I was confused about why I had to choose this 80km transceiver instead of a 40km one. AM told me the 40km CWDM SFP+ cannot meet the power loss of the whole link, so it was better to use 80km one. Thanks to her suggestion, everything is OK now.
