I am very pleased about the products. They are very high quality materials. It looks like you give a lot of attention to details, like how to pack the products, what materials it is used.

Yes, we received them and have installed them already. As usual everything is all good with your products :)

That's great. I want to compliment you. Your customer service is just amazing.

I bought the filters to use with the EDFA in the DWDM solution, the insertion loss and polarization dependence are low, excellent!

I bought the wrong connector, the customer service help me change the new filters immediately, so sweet!
