Sumitomo Electric Develops QSFP-DD 400G-FR4
March 13, 2018
Sumitomo Electric Industries, Ltd.
Sumitomo Electric Industries, Ltd., a leading global provider of advanced optical solutions, announced the availability of QSFP-DD 400G-FR4. The 400G-FR4 is compliant with the newly released specification on the 100G Lambda multi-source agreement (MSA).
The QSFP-DD MSA Group is addressing the technical challenges of achieving a double-density interface and ensuring mechanical, electrical, thermal and signal-integrity interoperability for module components produced by different manufacturers. Cloud data centers are driving growth while 5G and Internet of Things (IoT) is driving interconnects and traffic. Bandwidth drivers include:
- Data moving inside DC's-Production of search results, security processing, etc.
- Bigger "pipes" from users-carriers for 5G
- Increase in microprocessor cores and bandwidth per core
QSFP-DD electrical interfaces will employ eight lanes that operate up to 25 Gbps NRZ modulation or 50 Gbps PAM4 modulation, providing solutions to up to 400 Gbps aggregate. By quadrupling aggregate switch bandwidth while maintaining port density, QSFP-DD will support continuing growth in network bandwidth and datacenter traffic. In addition, systems designed with QSFP-DD modules are backwards compatible, allowing them to support existing QSFP modules and provide flexibility for end users and system designers. The QSFP-DD FR4 supports 2-km reach over duplex single mode fiber.
Sumitomo Electric will demonstrate the QSFP-DD 400G-FR4 at its booth #2923.
