SUNNYVALE, Calif. -- Cortina Systems® (Cortina), a leading supplier of intelligent communication solutions, today announced the 10GE industry enabling Electronic Dispersion Compensation (EDC) family, the CS4212 and CS4217. The CS4212 and CS4217 will enable 10GE enterprise, metro and core market segments across all form factors through their size, low power and availability. Cortina’s CS4212 enables the industry move to SFP+ by increasing multi-mode fiber reach to more than 300 meters. This allows a single board design for all SFP+ module types and also makes possible for higher density line cards to be used due to the low power and small footprint. Cortina’s CS4217 enables optical module suppliers to build devices compliant with the 10GBASE-LRM standard. The low power and small footprint allows X2 and XFP modules to be built for legacy multi mode fiber in the enterprise. ”SFP+ has the potential to reduce the 10G overall systems cost and drive 10GE to volume shipments,” said Scott Feller, product line manager at Cortina Systems. “Cortina is seeing the market take off with the CS4212 and CS4217 shipping more than 40,000 ports in the first quarter of this year.” The Cortina Systems® CS4212 Electronic Dispersion Compensation Device (CS4212 EDC) is highly integrated with four 10 Gbps clock and data recovery (CDR) circuits. Two channels have the optional capability for integrated Electronic Dispersion Compensation (EDC). This functionality supports 2 SFP+ modules that can be either limited or linear. Enabling the EDC capability allows the device to operate with linear SFP+ optical modules to extend the operating range of 62.5 um and 50 um multi-mode fiber to 300 meters and beyond. The device is fully autonomous and does not require external processors to control the initial convergence or the dynamic adaption of the dispersion compensation. The Cortina Systems® CS4217 Electronic Dispersion Compensation Device (CS4217 EDC) is a highly integrated dual port 10 Gbps clock and data recovery (CDR) circuit. The receive path has integrated EDC to allow optical modules to extend the operating range of 62.5 um and 50 um multimode fiber to 300 m and beyond. The device is in a 6mm by 6mm package to allow easy integration in to optical modules. The device integration and low power design techniques allow XFP 10GBASE-LRM modules to be built under 1.5 W.
