I am very impressed with the customer service from FS.com. The notifications I received from ordering, to shipping, to you following up have been fantastic. Thank you for the excellent customer service. I will definitely be a returning customer.

Thanks for reaching out, all the stuff we got from you all is great so far! We will keep FS in mind when purchasing in the future when new needs arise.

My device is a Cisco Nexus 93180YC-FX, and I purchased some 10G 1270nm CWDM modules. Because I was not sure if they would be compatible with my equipment, I asked for help testing before I purchased them, and my account manager gave me quick feedback on the test results. When I bought it back it was fully compatible with my equipment and worked great.

Need to use this product on Cisco Nexus 9000 series and just can't confirm if it's compatible with my device. Purchased two at AM's suggestion and tested them which worked very well on my device.

The product has worked flawlessly in my Cisco switch and achieves 10Gbps rate. Thank you for offering such a great product at such a reasonable price.
