05/05/2008 Cortina Systems: "Cortina’s CS4212 Passes Ethernet Alliance SFP+/EDC Interoperability"
Cortina Systems® (Cortina), a leading supplier of intelligent communication solutions, announced the 10GE industry enabling Electronic Dispersion Compensation (EDC) family, the CS4212 successfully interoperated with every SFP+ optical module at the SFP+/EDC interoperability plugfest, hosted by the Ethernet Alliance at the University of New Hampshire Interoperability Lab. 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.  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.  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.
