DECEMBER 18, 2006 -- Aeluros (search for Aeluros) today announced the availability of its second-generation 10-Gigabit Ethernet (GbE) PHY/SerDes devices with integrated electronic dispersion compensation (EDC) for 10GBASE-LRM (search for 10GBASE-LRM) applications.
Targeted for both XAUI-based optical modules and the emerging SFP+ systems applications, the new devices are built upon the earlier generation of the Puma AEL1003, say company representatives. Like the Puma AEL1003--a highly integrated device with full PCS, PMA, and XGXS sub-layer functionality--the new devices feature what the company claims is the industry's lowest power dissipation.
This latest generation of integrated EDC/PHY/SerDes devices from Aeluros incorporates performance enhancements to the original EDC engine that was demonstrated at OFC/NFOEC in March 2006. Enhancements include improving the robustness of the EDC algorithm to address not only the standard stress test pulses defined in the IEEE 802.3aq specifications for 10GBASE-LRM, but also more stringent corner cases that could simulate real-world deployment situations and identify the real breadth of the EDC engine's performance characteristics, says the company.
Aeluros' EDC technology has been extensively tested against various receive optical sub-assemblies (ROSAs) with different "linear" transimpedance amplifiers from different vendors to ensure interoperability with a variety of configurations that would be encountered in X2 optical modules and SFP+ line-card applications. In addition to the standard IEEE stress tests available through optical testers, Aeluros has tested its EDC technology with internally developed stress tests and with high-DMD fiber combined with pre-production SFP+ modules. Aeluros intends to make these tests available to its systems-customers.
"We have focused on developing a very robust EDC engine for our integrated PHY/SerDes devices,"Icontends Stefanos Sidiropoulos, co-founder and CEO of Aeluros. "With a robust EDC function suitable for XENPAK/X2 modules and SFP+-based line-cards, Aeluros is well positioned to address the requirements of both existing and emerging systems architectures," he says.
Samples of the device will be available to Aeluros' modules customers in 15- x 15-mmI BGA packages and to its line-card customers in 10- x10-mm packages to allow for high-density architectures driven by the emerging SFP+ based system architectures.
