S4120-1048

Stand-alone 10 Gigabit Ethernet Media Converter
10GBase-T Copper to Fiber

Product Brief

The S4120 is a stand-alone media converter that provides an interface between 10GBase-T ports and 10GBase-X slot via an open SFP+ port, allowing users to convert their 10Gig Ethernet ports to the preferred type of cabling used in their networks. The open SFP+ slot supports a wide variety of Transition Networks 10GE SFP+ fiber modules. Operating at Layer 1, the physical layer, data is passed through the converter at line speed, making the S4120 ideal for applications where low latency is essential. The ION S4120 can be managed, in-band, over the fiber, when it is linked back to a C4120 card installed in a managed ION chassis.
