STOCKHOLM -- Building on a number of Layer 2 Ethernet developments in 2008, Transmode, announces the extension of Layer 2 functionality to the Transport domain with the new 12 port Layer 2 Ethernet Muxponder. The new unit aggregates 10x Gigabit Ethernet signals but uniquely has a 10 Gigabit Ethernet LAN output for direct interconnection with switches and routers enabling compact and cost efficient aggregation of Gigabit Ethernet and better network utilization.

Building on two of the company's core competencies, Layer 1 Muxponders and Layer 2 Integration into WDM, Transmode has developed the new Ethernet Muxponder with both Layer 1 and Layer 2 aggregation. The Ethernet Muxponder has 12 ports, 10 Gigabit Ethernet SFP ports and two 10 Gigabit Ethernet XFP ports. The use of SFPs and XFPs in all ports ensures the Ethernet Muxponder supports all necessary range options of CWDM and DWDM and all necessary client port options - CWDM, DWDM or inter-office connections.

In a typical configuration the Ethernet Muxponder supports 10 client ports running at Gigabit Ethernet rates and aggregates these into a Layer 2 protected 10 Gigabit Ethernet LAN signal using the two 10G ports. As the uplink is 10 GbE LAN signal, it does not require demultiplexing in the optical domain and can be plugged straight into a switch or a router.
