The DS33M30 family of products provides a compact and efficient solution for transporting Gigabit Ethernet traffic over OC-3/STM-1 optical networks. With the addition of an optical transceiver, Ethernet PHY, DDR SDRAM, and host processor, a complete solution of GbE over OC-3/STM-1 can be implemented. The family supports Ethernet over SONET/SDH (EoS) at VC-4, "Next-Generation" EoS higher order mapping with multiple concatenated VC-3s, and Ethernet over PDH over SONET/SDH (EoPoS) with up to three virtually concatenated DS3/E3 tributaries. The supported frame encapsulations include GFP-F, HDLC, cHDLC, and X.86 (LAPS).

An evaluation kit is available: DS33M30DK DS33M33DK
