The product is very suitable for my cisco switch, and I have purchased several, looking forward to their follow-up performance.

Very Pleased with Quick shipping. SFP worked with Cisco UBR10k router just like FS said. Will definitely be doing more business with them.

Very good Int. logistics in 7 days the order arrived at ARG.

My preliminary test results are such that the XFP SR optics are performing exceptionally good on Cisco 6500. I just left my laboratory in my testing and I will deploy tomorrow in the live topology. I will definitely work with FS.COM again, should some new business arise.

FS technical team was good support for fixing my technical issues while ordered the product.

What a lovely company to deal with, great customer service. I will be back. Thanks for a prompt delivery and lovely quality items.
