Cypress samples single-chip framer for 10 Gigabit Ethernet and OC-192c/STM-64 packet over SONET/SDH

Fiber Optics Weekly Update, May 24, 2002

Cypress Semiconductor announced that it is sampling POSIC10G (CY7C9547-FAC), a single-chip framer that makes it possible to extend 10 Gigabit Ethernet (10 GbE) LANs over standard SONET/SDH networks. Supporting 10 GbE WAN PHY, 10 GbE LAN PHY, OC-192c/ STM-64 and direct mode, POSIC 10G reduces network and linecard complexity while enabling carriers to offer cost competitive 10 GbE services over MAN/WAN networks. POSIC10G follows closely on the heels of Cypress's sampling of POSIC2GVC, its full-featured OC48/STM-16 framer with virtual concatenation.

Operating in four modes, POSIClOG enables edge and core router designers to use the same design for multiple cards in their system, considerably simplifying linecard design. POSIC10G is a true single-chip 10 GbE solution that integrates a 10 GbE media access controller (MAC), a SONET/SDH framer, a Physical Coding Sub-Layer (PCS), and a WAN Interface Sub-layer (WIS). The device efficiently handles 10 GbE packets, supporting jumbo frames and address filtering. POSIC10G supports SPI 4.2, the industry standard for network processor interface on 10 Gbps linecards. The chip provides advanced support for SONET's automatic protection service (APS), having two on-chip SONET/SDH framer blocks. The APS switching/recovery is both manual and automatic, enabling flexible redundancy options for customer networks.

Enterprises can now connect their LANs to SONET/SDH-based access equipment. They can achieve high performance with a simpler network architecture, eliminating the need for protocol conversion, since the traffic remains IP/Ethernet based. This arrangement ensures cost effective bandwidth for the LAN from switch to switch, efficiently aggregating 10 GbE over SONET/SDH. POSIC10G is the only framer in the market today to enable enterprises to extend their 10 GbE network range to 20 km. Enhanced packet buffer memory helps prevent packet drop due to network congestion.
