Great value and works really well! So far so good.

Ordering from your company has been amazing so far, getting things quickly in a pinch has saved me twice now!

Got this PA-EDFA with their dispersion compensation modules for our long-haul DWDM transmission. It works great on our single fiber link. The loss is within our expected range and the optical signals transmitted and received are stable. Using these devices helped us to save many fibers and other fees. Will consider other products again.

I have shopped at FS for years. They made satisfactory customization and delivery every time. The Polarisation Maintaining EDFA I got this time worked as expected to boost 1 mW output of a c-band tunable laser to around 100mW, which we could monitor via the simple management tool. Had the module inserted in the 1U managed chassis sit on the rack. The modules themselves and the 1U chassis have proven to be of very good quality. Highly recommended!

We were interested in the EDFA but wondered whether the EDFA could work with our 200G DWDM module from another vendor, so we contacted the FS tech team for confirmation. They checked the datasheet of our module and assured us that the EDFA could work with the 200G module. Then they asked us about the optical loss of the whole link and recommended the 17dBm EDFA to ensure our power budget. The guys told us, we also needed an FMT chassis #39214 to install and manage the EDFA. At last, we bought two EDFAs and chassis. The chassis suit our 19-inch rack, and deployed EDFAs in our system, the 200G modules worked normally.
