WESTLAKE VILLAGE, Calif. -- Inphi® Corporation (, the world leader in analog performance and signal integrity, today announced successful interoperability demonstration of its Electronic Dispersion Compensation (EDC) and Clock Data Recovery (CDR) technology at the SFP+/EDC interoperability plugfest, hosted by the Ethernet Alliance at the University of New Hampshire Interoperability Lab (UNH-IOL). Inphi’s device, paired with every SFP+ optical module present at the event, met and exceeded the 10 Gigabit Ethernet (IEEE 802.3ae) transmitter optical eye mask and jitter requirements. In addition, the device demonstrated error-free performance as a receiver behind all SFP+ modules when put against the worst optical transmitter. Inphi’s patented and field proven analog signal processing engine delivers a high performance, low power EDC/CDR product for use in 10 Gigabit Ethernet modules and systems. In addition, as an established vendor of transimpedance amplifiers (TIAs), Inphi is well positioned to address the system challenges between SFP+ modules and its physical layer devices on a line card.

The testing was recently held at the University of New Hampshire Interoperability Lab (UNH-IOL) by the Ethernet Alliance SFP+/EDC subcommittee, and demonstrated multiple SFP+ SR and LR optical transceivers and physical layer (PHY) ICs interoperating over 270 meters of OM3 multimode fiber and 10 km of single-mode fiber. In addition, the group demonstrated multiple SFP+ -SR and -LR optical transceivers and PHY ICs interoperating with XENPAK, X2, and XFP optical transceivers over the same distances.

“The success of this plugfest indicates the readiness of silicon and module vendors to support SFP+ platforms, which will enable mass adoption of 10 Gigabit Ethernet,” said Marco Mazzini of Cisco and the Technical Champion of the Ethernet Alliance SFP+/EDC Subcommittee.
