AMCC, Gennum demo 10GBase-LRM Interoperability

OCTOBER 15, 2008 -- Applied Micro Circuits Corp. has announced interoperability between its QT2025 10-Gbit/sec PHY with EDC and Gennum Corp.'s GN3052 ROSA for 10GBase-LRM applications.

OCTOBER 15, 2008 -- Applied Micro Circuits Corp. (AMCC; search for AMCC) has announced interoperability between its QT2025 10-Gbit/sec physical layer device (PHY) with electronic dispersion compensation (EDC) and Gennum Corp.'s (search for Gennum) GN3052 ROSA for 10GBase-LRM applications.

Together, these products show more than 6 dB of OMA sensitivity margin over operating conditions, PCB trace lengths, and IEEE 803.2aq 10GBase-LRM stressors, delivering significant performance advantages including best-in-class sensitivity and very high gain, AMCC asserts. Gennum's SFP+ ROSA and AMCC's QT2025 have also demonstrated interoperability in SFP+, X2, XPAK, and XENPAK applications, the company adds.

"AMCC's EDC and 10GbE PHY technology provided key elements in achieving outstanding 10GBase-LRM results in interoperability testing with Gennum's ROSA," said Gary Beauchamp, senior vice-president and general manager, Optical Products, Gennum Corp. "Gennum's GN3052 ROSA provides automatic gain control (AGC) functionality specifically designed for emerging applications utilizing EDC such as 10GBase-LRM."

AMCC's QT2025 is a fully integrated 10-Gbit/sec transceiver with fully adaptive EDC. It provides a high-performance interface between a MAC or a switch device and optical modules. The QT2025 is also capable of interfacing directly to SFP+ direct attach copper cabling and to 10GBase-KR backplanes.

According to Neal Neslusan, director of marketing at AMCC, "The demonstration of interoperability provides a clear indication that 10-Gbit/sec datacom traffic can be successfully transmitted over greater distances to meet the highly demanding 10GBase-LRM specification. It is yet another milestone for deploying 10G in the market."
