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.

buen producto de buena calidad, se acopla de inmediato.
