As data rates continue to increase, speeds up to 112Gbps require backplane connections with improved signal integrity (SI) and reduced crosstalk and channel loss. These connectors must also be compact enough to provide more functionality in less space while supporting versatile and high-performance solutions like cabled and hybrid connections. 

Adopting connectors that support reliable, high-quality 112Gbps connectivity helps meet demands for added speed and improves overall system performance. Using cabled solutions moves longer circuits off the PCB, saving energy and operating costs by reducing the need for re-timers. Miniaturized solutions improve airflow and increase the number of ports per rack unit, reducing costs, while scalable and adaptable solutions save time by streamlining upgrades and simplifying integration into existing infrastructure.

The Impulse Backplane System delivers reliable 112Gbps PAM-4 data speeds with reduced insertion loss and exceptional SI, helping improve system performance and reliability. With a dense, modular interface featuring 101 pairs per square inch, Impulse connectors optimize PCB real estate and support more efficient thermal management by enhancing airflow. The robust design offers cable and hybrid solutions that deliver best-in-class SI performance and support various channel lengths, improving design flexibility and making upgrades easier.

This is not a definitive list of applications for this product. It represents some of the more common uses.

What are the advantages of cable cartridges and cabled backplane solutions?
Molex’s high-performance twinax cable reduces insertion loss compared to standard PCB materials. The benefits of cable backplanes include greater design flexibility, the removal of energy-hungry re-timers and a reduction in system-level power consumption. Robust, blind-mate cable cartridges from Molex are easy to install and provide best-in-class channel performance.

What are the advantages of Impulse hybrid cables?
Impulse hybrid cables routed to CX2 and Microbeam near-ASIC 112G connectors enable connectivity between customers’ backplanes and chips through high-performance cable. These can be used in parallel with Impulse OD RAM connectors to implement partially cabled architectures. This approach gives hardware designers greater design flexibility and can help them avoid utilizing costly re-timers.

What are the advantages of Impulse orthogonal and conventional connectors?
The robust form factor of the Impulse system supports up to 128-pair connectivity with easy-to-install compliant-pin board termination. This compact form factor maximizes system airflow and reduces cooling requirements in both orthogonal and conventional applications. Conventional vertical risers are popular in switch applications where Impulse can enable designers to maximize port density on the faceplate without sacrificing signal integrity.
