We need a large quantity of 10G optical transceivers for our new data center. Restricted by a limited budget and a tight schedule, I count on FS to provide a cost-effective solution for me. My account manager is rather professional and patient to answer all my questions, really nice conversations we have. I have to praise your fabulous customer services. And the modules were well-packaged and worked perfectly on our switches. Will recommend you to my friends in this field.

I bought the S3900 switch on your website, so I need several SFP+ optical modules to support 10GbE. These 10G transceivers that can provide 10GBase-CWDM throughput up to 20km over SMF are suitable for my needs. Neat facade, easy to install, and works smoothly with the switch. Fairly nice!

The modules were implemented in our CWDM network. On our Cisco switches, the modules ran nice and their TX and RX were within spec.

Using these products for the Cisco switches we just deployed. Just worked so well. I have no single problem with them until now and I would like to recommend them to anyone who has the need.
