Applied Micro Circuits (News - Alert) Corporation has announced interoperability between its QT2025 10-Gigabit per second (Gbps) physical layer device (PHY) with electronic dispersion compensation (EDC) and Gennum Corporation’s GN3052 ROSA for 10GBASE-LRM applications.

 

The interoperability has been demonstrated in an effort to prepare 10GBASE-LRM technology for high speed datacenter connectivity. According to company’s officials, these products together show more than 6dB of OMA sensitivity margin over operating conditions, PCB trace lengths and IEEE (News - Alert) 803.2aq 10GBASE-LRM stressors. Together they deliver significant performance advantages including best-in-class sensitivity and very high gain.

 

Gennum’s SFP+ ROSA and AMCC’s (News - Alert) QT2025 are also interoperable in SFP+, X2, XPAK and XENPAK applications.

 

Senior Vice-President and General Manager, Optical Products, Gennum Corporation, Gary Beauchamp noted that AMCC’s EDC and 10GbE PHY technology provided key elements in achieving outstanding 10GBASE-LRM results in interoperability testing with Gennum’s ROSA.

 

The company’s GN3052 ROSA provides Automatic Gain Control (AGC) functionality specifically designed for emerging applications utilizing EDC such as 10GBASE-LRM. He also claimed that Gennum’s unique AGC architecture in the GN3052 provides the industry’s best stressed sensitivity when used with major EDC solutions.

 

AMCC’s QT2025, a fully integrated 10 Gbps transceiver with fully-adaptive EDC, provides a high-performance interface between a MAC or a switch device and optical modules. The product can also interface directly to SFP+ direct attach copper cabling and to 10GBASE-KR backplanes. Leveraging AMCC’s transport components, system designers are able to offer a cost-effective, high-performance, high-capacity delivery of enterprise traffic for 10-Gigabit Ethernet datacenter applications.

 

The market for 10 Gbps connectivity technology is growing as more system designers seek to add higher performance links in datacenters, according to Neal Neslusan (News - Alert), director of Marketing at AMCC.

 

He pointed out that Gennum’s ROSA-based solutions offer all of the features and performance that designers want for these applications. Neslusan believes that the demonstration of interoperability provides a clear indication that 10 Gbps datacom traffic can be successfully transmitted over greater distances to meet the highly demanding 10GBASE-LRM specification.

 

Part of Gennum’s ROSA product line, the GN3052 provides solutions for 10 Gbps applications including limiting and linear (AGC) ROSAs covering 850nm to 1550nm.
