Very happy with the modules and services offered by FS.com. I ordered QSFP+ modules to fit for my computing networks. They can receive and forward without frame loss. Customer service was excellent, I had queries to the technical team about what I was ordering and to the sales team about the delivery, each time the response was helpful, accurate and professional.

We always have a wonderful shopping experience here. We were looking for some 40G transceivers with low power consumption of less than 4.5W for our Cisco ASR 9000 Series switches. Then our Account Manager gave us a quick response and recommended the QSFP+ UNIV and QSFP+ SR modules. Considering the existing LC cables we have, we chose the first solution and ordered twenty QSFP+ UNIV transceivers. We were happy they came without breakage. FS always does a good job of packaging and delivery. We plug them into our switches and they are recognized immediately. As they are supposed to be, they are plug and play as well as fully functional in our Cisco switches. No compatibility problems so far. They have worked flawlessly and operated at a full speed, no packet loss or interface issues or anything like that. Much thanks to FS!

This isn’t the first time I've ordered fiber optic products here. The services they provided were out of my expectations every time. All FS guys were very enthusiastic, professional and gave me a quick response to every problem I encountered. Also the modules can work flawlessly with my Cisco gear. Five stars!
