The Cortina Systems® CS4315 Electronic Dispersion Compensation Device (CS4315 EDC) is highly integrated with four 10 Gbps clock and data recovery (CDR) circuits. The two receive channels have the optional integrated  Electronic Dispersion Compensation (EDC) capability. 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 μm and 50 μm multimode fiber to 220 meters and beyond, and greater than 7 meters of Direct Attach Copper cable.
