10SummariesXFP modules are lower power, smaller form factor, lower cost for higher line card density over competing solutions10G electrical interface is more challenging compared to XENPAK based modulesReference system has demonstrated feasibility of the XFP host system, with significant margin on 10G electrical interface.
