New DSFP (Dual Small Form-Factor Pluggable) Transceiver Specification Released
The DSFP Hardware Specification Rev. 1.0 has been published on
To address the growing port density and scalability requirements of Wireless and 5G Mobile infrastructure, the DSFP specification doubles the data rate and port density of SFP modules. SFP has a single electrical lane pair operating at bit and data rates up to 28 Gbps using NRZ and 56 Gbps using PAM4. DSFP has two electrical lane pairs, each operating at bit rates up to 26 Gbps using NRZ and 56 Gbps using PAM4, supporting aggregate date rates up to 56 Gbps and 112 Gbps, respectively. DSFP will potentially scale to a per lane bit rate of 112 Gbps using PAM4, supporting aggregate data rate up to 224 Gbps. SFP modules can be plugged into DSFP ports for backwards compatibility.
“We are very excited about the introduction of a highly competitive new form factor by the DSFP MSA, which will double interface bandwidth and port density while maintaining compatibility with the existing SFP family of optics,” said Zhoujian Li, President of Research and Development, Wireless Networks,
“Publication of the DSFP Hardware Specification is part of an industry trend of quickly developing solutions optimized for specific applications. Stringent cost, power and size constraints in demanding market segments, like Mobile infrastructure, leads to solutions focused strictly on required functionality,” commented
“TE works closely with our customers and end equipment operators to understand their requirements and meet the market needs”, according to
“There is tremendous industry pull for higher speeds and densities on switches and servers, while maintaining backwards compatibility. The DSFP form factor achieves this by doubling the number of high-speed lanes in the same size package as SFP,” said
“As technology demands continue to evolve, Molex is delighted to be a part of the DSFP MSA and contribute to the development of the new form factor,” said
“DSFP form factor doubles bandwidth density by doubling the number of channels in SFP size module, to support future demands of 5G network traffic,” commented
