Molex Drives Development of Network Technologies

Molex serves in leadership roles in Multi-Source Agreement (MSA) Groups aimed at fostering development of new high-speed, high-density interfaces and links used in telecommunication, data center equipment and networking platforms, <>.

An established technology leader, Molex is a founding promoter, editor and member of the QSFP-DD (Quad Small Form Factor Double Density) MSA, the SFP-DD MSA, and the 100G Lambda MSA groups, all of which support multi-vendor interoperability.

Established in 2016, the QSFP-DD MSA has released an updated 3.0 hardware specification for the new QSFP-DD form factor. A QSFP28 compatible double-density interface, QSFP-DD pluggable modules can support up to 400 Gbps in aggregate over an 8 x 50 Gbps electrical interface–quadruple the bandwidth of conventional QSFP modules, allowing networking equipment to keep pace with advances in ASIC (application-specific integrated circuit) technology.

Systems designed for QSFP-DD modules will be backwards compatible with existing 28 Gbps QSFP and QSFP+ form factors and provide flexibility for end users, network platform designers and integrators. Providing excellent signal integrity and thermal protection, Molex QSFP and QSFP+ Integrated Product Solutions support Ethernet, Fibre Channel, SAS and InfiniBand applications.

Established in May 2017, the SFP-DD MSA recently released the initial hardware specification and drawings for the SFP-DD electrical interface. The SFP-DD specification builds on a full range of Molex SFP+ and SFP Interconnect Solutions, including cages, connectors and cable assemblies, and optical modules. Targeting support for thermal management up to 3.5W optical modules, the new interface features two lanes that operate at up to 56 Gbps per lane, providing throughput of 116 Gbps over the two lanes with PAM-4 modulation. By doubling the lane density and data rate of an SFP connector, the SFP-DD interface will significantly boost port density and deliver optimal scalability in networking cables and equipment.

Most recently, Molex and other industry leaders established the 100G Lambda MSA to develop specifications based on 100 Gbps per wavelength optical technology, and addressing the technical challenges of achieving optical interface interoperability for transceivers produced by different manufacturers.

Molex provides industry optoelectronic solutions for broad range of high speed networking applications. By close collaboration with industry leaders, we are driving industry adoption of 100G Lambda MSA, which effectively doubles the data rate per wavelength for 100 Gbps and 400 Gbps applications with extended reach to 2km and 10km, and also provide a technology platform required for next generation networking equipment.

Molex brings together innovation and technology to deliver electronic solutions to customers worldwide. With a presence in more than 40 countries, Molex offers a full suite of solutions and services for many markets, including data communications, consumer electronics, industrial, medical, automotive and commercial vehicle.
