The product advertised was exactly what I received, on time, and installation instructions were accurate. My order went well! I did not have to contact customer service. I would definitly order from them again!

Those optics we bought earlier in the week arrived lightning fast! I know small order but it was urgent need. they arrived fast as needed

I use FS.com's XFP modules and has saved us a metric ass ton of fiber cores. Optics installation is easy and hassle-free.

The rep who assisted me was very knowledgeable and helpful when determining how to get the product to our warehouse quickly. Great service. Will use fiberstore again.

Used these to replace some old transceivers, very nice build quality. I was very pleased with the service and exactly the XFP transceivers I need. This is the way to shop. I will be spreading the word to be sure.

Fast shipping, good quality, great price. No problems at all.

Tried contacting optical company directly, several times, to no avail. Finally remembered this great place. Ordered it no problem, here in 10-12 days. Thank you FS.COM !

At first I thought it might be hard for me to find the compatible Cisco XFP modules from a Chinese OEM vendors, but it is so amazed to order from Fiberstore wth competitive pricing. I will come again!

Impressive customer service and fast shipping. Waiting to see whether the working performance of these XFP is good or not.

Excellent! I have purchased multiple items from Fiberstore and they always have the hard to find items at reasonable costs and fast shipping. 10GBASE-ZR XFP is tested to be fine on my Brocade switch and can offer up to 80km. But one thing I need to complaint is that the shipping fee is high.
