Exar Intros GbE Mapper

Exar introduced an optimized Gigabit Ethernet (GbE) Mapper for access and transport applications in C/DWDM networks. The new GEM250 mapper provides direct connection to GbE PHYs on the client side and SDH/SONET SerDes on the line side. It combines all the functions necessary to multiplex 2 Gigabit Ethernet streams into a single 2.5 Gbps signal. Integrated GbE MACs provide Ethernet statistics while Ethernet frames can be encapsulated with HDLC or GFP. All SDH/SONET Regenerator/Multiplex Section and Trail/Path monitoring functions are also implemented in hardware. http://www.exar.com
