OM1412 [EoS HOLO VMAP 10G]

Download Datasheet The OM1412 Virtual ASSP is an highly integrated, ultra compact 10Gb/s, High and Low Order, Ethernet over Sonet/SDH Packet Mapper targeted to the Xilinx Virtex 5 Family. 10Gb/s of channelized Ethernet is transported over High Order or Low Order Sonet/SDH (EOS) using standards complaint GFP-F, VCAT and LCAS. Up to 25% of the 10G bandwidth can be low order traffic. The 'packet' interface is SPI4.2 and supports 192 channels allowing more individual customers to be handled on a single device further reducing opex. The 'Sonet/SDH' interface is 10Gb/s 1+1 protected TFI5 interface for high reliability carrier grade deployments. The OM1412 handles both 'Real Concatenation' (CCAT) and 'Virtual Concatenation' (VCAT).

In addition, LCAS is supported to allow group bandwidth to be hitlessly increased or decreased as customer need dictates. The OM1412 has been designed from the ground up as cost effective ASSP replacement in an FPGA – ultra-compact IP targeting the lowest cost FPGA, highly integrated design with CDR, Framer, Mapper and SPI4.2 interface in a single package, 32bit wide DDR2 for external packet buffer and external differential delay memory (up to 64ms), Software Device Driver and on-chip debugger and supporting toolchain - all lower cost and accelerate TTM.

Typical applications are in Metro Core head end products supporting many EOS VCAT/GFP streams from multiple Access Network customers into a single 10GbE stream for handoff to the Data Core Network.
