We have received the products and they turn out to be the right choice for our high-speed networking needs.

Some of the LR transceivers we purchased last month have been put in use and are working as expected, so that's great. We're now in the process of adding some more fiber cables between our buildings and logged in the site to compare prices between LR and SR transceivers.

If you have Mikrotik devices and you need 10GBASE-LR modules, use the customized one. Works 100%. Awesome product. +1 also for customer service. Thank you.

Awesome service, FS has delivered the order in my country in less than a week.
