Ethernet Over SONET/SDH Mapper

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 high-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). By Maxim Integrated Products
