The SFP-DD MSA Group (Small Form Factor Pluggable Double Density Multi Source Agreement Group) releases the v2.0 specification for the SFP-DD pluggable interface.
This new release dedicated to cultivating the development of next-generation SFP form factors used in high-speed DAC (Direct Attach Cable) and AOC (Active Optical Cable) cabling, and optical transceivers, the MSA consortium released the initial SFP-DD specification version 1.0 in September 2017 and earlier this year released version 1.1.
The newly updated specification version 2.0 reflects enhancements to the mechanicals, extended modules and enhanced polarizing key of the high-speed, high-density SFP-DD electrical interface, targeting support of up to 3.5 W optical modules in an enterprise environment.
The SFP-DD form factor addresses the technical challenges of achieving a double-density interface and ensuring mechanical interoperability for module components produced by different manufacturers. The innovative electrical interface is designed to support two lanes that operate up to 25Gbps NRZ or 56Gbps PAM4 per lane modulation — providing the aggregate bandwidth of 50Gbps NRZ or 112Gbps PAM4 with excellent signal integrity.
‘’Through strategic collaborations, we work to increase speed, density, and scalability in next-generation servers,” said Scott Sommers, Chair of the SFP-DD MSA. “We effectively enhance the roadmap in network applications to meet the challenging demands of data centers and enterprise networking platforms are up against.”
