Cortina adds new member to its 40G/10G optical transport processor family

Cortina Systems, Inc. has announced 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. The CS604x family is pin for pin and software compatible with the previous generation, CS600x, and adds support for latest OTN mapping standards, ODUFlex, and 40G Ethernet. To enable direct connection to new lower cost 40G modules such as QSFP and CFP, the CS604x has four additional 10G multi-rate serial interfaces. Cortina claims CS604x family is the industry's first OTN processor family with integrated jitter attenuation PLLs.

"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."

"During 2010, total 40G port shipments doubled on optical equipment, with most being used for multiplexing 4x10G traffic," said Andrew Schmitt, Directing Analyst, Optical at Infonetics Research. "Aggregation of high density 10Gbps is the sweet spot for core deployments based on data center interconnect and broadband aggregation, which is addressed by the Cortina CS604x with its ability to transparently map and transfer 10G and 40G clients to OTN, OTU3(e) and OTU4, in a standard fashion."

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. 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.

"Time to market is critical to our customers. The Cortina CS604x family not only extends the previous generation CS600x's leadership in the Optical core and metro networks, it provides 100% software and hardware compatibility," stated Zarabi. "The CS600x is deployed in products at many tier 1 and 2 OEMs. The hardware and software APIs are proven and give our customers a seamless transition and upgrade path."

The CS604x family has been sampling to customers since March 2011.
