Cortina Debuts 2nd Gen 40G OTN Processor

Cortina Systems is now sampling its second generation 40G/10G optical transport processor family, CS604x, designed for transport and aggregation of data, voice, and video signals simultaneously over 10G, 40G, and 100G networks.



Cortina said its updated processor is aimed at the growing adoption of 40G Ethernet transport, as these trunks will require the cost-efficient aggregation of 10G connections. Recent OTN standards ratification for GMP mapping and ODU0 and OTN Switching will accelerate this trend. Cortina has integrated jitter attenuation and cleanup PLLS to help in a variety of applications, including packet optical transport platforms, DWDM transport systems, Carrier Ethernet switch/routers, and submarine line termination systems.



The new CS604x family retains pin for pin and software compatibility with the company's previous generation, CS600x, and adds support for latest OTN mapping standards, ODUFlex, and 40G Ethernet. It offers four additional 10G multi-rate serial interfaces for direct connection to QSFO and CFP 40G modules.



"Telecom equipment makers are looking for integrated solutions that reduce their BOM cost, board space, and power consumption, while supporting the latest standards and technologies enabling them to transport legacy and emerging packet-oriented services transparently," said Arun Zarabi, Vice President, Infrastructure Business Unit, Cortina. "The Cortina CS604x four jitter attenuation and cleanup PLLS provide significant savings to customers in both board space and cost in asynchronous demapping applications, when compared to external PLL based solutions needed with competitor products."



The Cortina CS604x Optical Transport Processor & FEC Devices integrate 40G Ethernet MAC enabling monitoring and mapping of 40GE clients to OTN, compliant with latest G.709 (Amendment 1 7/2010) & G.798 (10/2010) standards updates for GMP mapping of various bit rate clients into OTN, four integrated jitter attenuation and clean up PLLs, and additional 4x10G multi-rate (OTL/STL/XLAUI) serial interfaces enabling single chip/single card design for CFP/QFSP to CFP/300-pin MSA transponder applications.



As with the previous generation, these devices support standard and strong Forward Error Correction (FEC) at 10G & 40G rates, and provide performance monitoring and networking support for various client signals including 10GE LAN/WAN, Fibre Channel, Infiniband, and SONET/SDH with connectivity to XFP/SFP+ and SFI4.1 MSA modules. http://www.cortina-systems.com
