Good customer service, friendly staff, good knowledge of products. Before I knew what I need, I ask several questions about the amplifier, except for the information shown on the site, the sales lady also sent me some detailed information about the test results of their engineers. Now the products have arrived on time, thanks.
Amplifiers are common components in WDM systems, expecially in long-haul transmissions. We bought this C-band amplifier to use between two 10G ethernet swtiches, it works perfect. I have got what I paid for. Highest recommendation!
The amplifier was a quality product and worked great. FS was always there to help me through my problems with options and information! This device is very simply but offers a satisfied signal, especially the nosie reduce in a great degree, not just increase the signal strength. I'm very happy with both product and seller!
These amplifibers were ordered to try to fix a problem in our long haul WDM systems. I received the booster amplifier on time and they did exactly what they were supposed to, they provide a perfect transmission for us. Now the network systems runs very well. Along this booster amplifier, we also buy some other components, all of them are arrived timely and ingood shape, thanks.
