Perle S-10G Media Converters transparently connect 10 Gigabit Ethernet links over multimode or single mode fiber. Each 10GbE Media Converter comes with two pluggable transceiver ports that support fiber to fiber, copper to fiber or copper to copper media conversion. The S-10GR additionally supports 10/100/1000/2500/10000 rate conversion. Fiber to Fiber and Copper to Fiber conversion is achieved by inserting XFP or SFP+ fiber transceivers that support multimode and single-mode fiber, including CWDM/DWDM wavelengths. Copper to copper is achieved by inserting SFP+ Direct Attach Cable (DAC), also known as twinax, or XFP 10Gbase-CX4 transceivers. The empty transceiver ports on the S-10G Media Converters allow for flexible network configurations to meet any requirement using a variety of 10G transceivers supplied by Perle, Cisco or other manufacturers of MSA compliant SFP+ and XFPs. You can use these products to convert: SFP+ to SFP+ XFP to XFP XFP to SFP+ SFP to SFP ( 1000Base-x to 1000Base-x ) SFP+ to CX4 10/100/1000/2500/10000 Ethernet Perle 10 Gigabit Ethernet to Fiber Converters provide an economical path to extend the distance of an existing 10GbE link.
