Stand-alone Fiber to Fiber Media Converter
SFP+ to SFP+ for Data Rates from 1 Gbps to 11.5 Gbps

  • S4110-768x771
  • S4110-4848-front
  • S4110-4848-back

The S4110 is a stand-alone fiber to fiber media converter. It is protocol independent and supports data rates from 1Gbps to 11.5Gbps through two open SFP+ slots. This allows network managers to customize the S4110 with a pair of SFP+ modules to meet their network requirements. The open SFP+ ports support a wide variety of Transition Networks 10GE SFP+ fiber modules. This any-rate to same-rate converter can be used to perform reliable and cost-effective single mode to multimode conversion or it can be used to provide wavelength conversion in CWDM applications.
