Compatible Modules and Cables for FS S3900 Series Switches

Posted on By FS.COM

The FS S3900 Series is a family of high-availability, low-latency Gigabit stackable Layer 2+ (Layer 3 Lite) switches that are built to fit the ever escalating Internet traffic and bandwidth demands. Ideally suited for ISPs and Multiple System Operators (MSOs) to provide triple-play services for home users, the FS S3900 switches are also powerful enough for deployment at the access and aggregation layer of SMBs, enterprise, and campus network. Here we provide essential information on the FS S3900 Series, including its key features and specifications, modules and cabling options.

Features and Benefits of FS S3900 Series Switches

The FS S3900 Series comes into three variants - S3900-48T4S, S3900-24T4S and S3900-24F4S. They are equipped with 1G copper/fiber downlink ports and 10G SFP+ uplinks (stack links) to provide a combination of low latency, non-blocking line-rate switching, and ease of management. Aside from the advanced features that bring high availability, comprehensive security, robust multicast control, and QoS to the network edge, S3900 Series also boosts powerful hardware design. The specifications are listed as following.
