Fujitsu and Gennum announced a case study on boosting data center bandwidth

Fujitsu Microelectronics Gennum Corporation jointly issued a new case study entitled "Reducing Power and Costs of 10G Solutions in Data Centers,"
This study provides a comprehensive description of a solution using Fujitsu's 26-port, 10GbE switch IC, the MB86C69RBC, with SFP+ modules embedded with Gennum's 10G CDR technology. Gennum says, use of SFP+ modules resulted in significant power savings, lower component count, and lower manufacturing cost.
The newly published report details how the proposed SFP+ architecture enables a $40 savings per port, along with reductions of up to 1W per port in power consumption.
The 10Gbps serial-capable I/Os directly connect to the 10GbE optical modules with integrated signal-conditioning devices, removing the added power requirement and cost that comes from using extra components in the path.
"Our goal in developing this SFP+ based solution was to eliminate the need for all components between the switch ASSP and the SFP+ optical module" said Bharat Tailor, director of marketing of Networking, Storage and Computing products at Gennum Corporation.
