JUNE 18, 2007 -- Cortina Systems Inc. (search for Cortina) has announced its second generation high-performance EPON switch chipsets, the CS8021 and CS8016.

Cortina describes the CS8021 as a highly integrated quad EPON OLT device with bridging and switching capabilities, and the CS8016 as a 1-Gbit/sec full bandwidth ONU device with complete traffic management and scheduling capabilities.

"Network operators and service providers need a distributed and scalable solution for FTTx networks," stated Zino Chair, vice president of marketing at Cortina. "Using CS8021 and CS8016, network operators and service providers can implement a low cost, carrier-class Ethernet broadband access solution with quality of service (QoS) and traffic management."

On the central office side, the CS8021 OLT is designed to simplify board design by supporting four EPON ports in a single chip, enabling equipment vendors to develop high-port-density chassis or stackable rack-mount systems. The dual Fast Ethernet management ports of CS8021 OLT allow vendors to build a redundant (fault tolerant) managing system. Additionally, the extensible SDRAM frame buffer facilitates QoS.

On the CPE side, the CS8016 ONU is designed to offer a wide range of QoS and traffic management services to ensure that bandwidth, delay, and jitter requirements for each ONU are met according to the traffic profile extracted from the service-level agreement. The CS8016 ONU also integrates frame buffer memory to eliminate the need for external RAMs.

The CS8021 OLT and CS8016 ONU work together to provide differentiated services for various categories of traffic to ensure preferential treatment to high-priority traffic such as voice and video. Both chips meet the Chinese Telecom Compliance requirements, Cortina says.
