With the accelerating pace of technological innovation and the growing market demand, modular design has become a key development focus in the data center field. Especially with the rapid advancement of edge computing and micro data centers, modular design not only enhances flexibility to adapt to technological changes but also brings significant cost control benefits.
▲ Detachable Backplane Design
Customer Challenge:
Scarcity of Suppliers
Mastering Detachable Backplane Design
Against this backdrop, detachable backplanes allow precise matching of PCB materials with different costs and performance based on signal speed. The customer in this case had such a need. However, suppliers capable of mastering detachable backplane design technology and ensuring stable signal transmission are extremely rare. This led to customer concerns about the transmission stability of detachable backplanes in data center systems. Therefore, finding a partner with both technical expertise and reliability was especially important for them. 
▲ Impel Plus Backplane Solution
Molex:
Industry Leader in Detachable Backplane Design
Molex is such a partner. With our extensive modular experience, we offer industry-leading detachable backplane designs, such as the Impel, Impel Plus, and Impact series products, capable of meeting transmission needs from 10G to 56G, with forward and backward compatibility, providing strong support for future system performance upgrades. Our multiple pitch options, combined with efficient signal traces, enable customers to flexibly design PCB layouts and reduce costs.
▲ Impel Series Backplane Solution
01. Impel/Impel Plus
Backplane Connectors
The Impel backplane interconnect system occupies minimal space, allowing customers to achieve data transfer rates of up to 40 Gbps without completely redesigning the architecture or replacing existing data center hardware, while meeting industry requirements for mechanical density.
The Impel Plus backplane connector system achieves data transfer rates of up to 56 Gbps, while providing optimal signal integrity through ground tail aligners (which minimize impedance discontinuities and reduce crosstalk). Additionally, the innovative signal interface reduces insertion loss compared to direct-plug signal beam interfaces, with frequencies exceeding 30 GHz.
Prototyping cable assemblies requires tools, which can result in significant costs. The Impel and Impel Plus backplane cable assemblies address tooling startup costs by providing complete assemblies.
02. Impact Backplane Connectors
The Impact backplane system, when using the Impact zX2 connector, provides data transfer rates of up to 28 Gbps. It is one of the most versatile connection products on the market, improving high-density packaging to meet the demands of the next generation of high-speed requirements.
