Good quality

Looking for cost-effective SFP fiber modules in our building to building run (12km and 30km). We already knew that FS had designed many customized cases for their clients, so we sent our project design to them and asked them for a clear connection for each node. They always replied in prompt service and provided us a whole connecting diagram. Also they marked the products we needed in the diagram below. We were very surprised by their professionalism and expertise. After negotiation, we decided to go with their suggestions and bought the modules and fiber optic cables here. Installed these modules on my Cisco switches, they offer a stable transmission for them without any compatibility issues or packet loss. Five stars for the good products and friendly people at FS. Excellent shopping experience here!

These modules were immediately picked up by my Cisco 4500 WS-X4724-SFP-E switches. After I plugged it into the port, the link promptly came up. Zero packet loss and no delay. Pretty high quality for someone who is looking to work with SFP and fiber in their project.
