Features and Benefits

Backplane Daughtercard Connector System

Backplanes and Daughtercards: Providing a 0.31mm standard through-hole and 32 to 128 differential pairs with a 2.00mm pitch, Impulse Backplane PCB Headers incorporate U-shield grounding for protection and has an innovative stub-less signal interface.
Orthodirect PCB Headers and Daughtercards: With the same outstanding capabilities as Impulse Backplane Connectors, the Orthodirect Connection System can support 90- and 270-degree orientations, making this an ideal complement to the Impel Orthodirect portfolio, providing even more flexibility and versatility.
Cable Solutions and Daughtercards: Impulse Cable Solutions include a hermaphroditic signal interface and twinax cabling made with microcellular, co-extruded fluorinated ethylene propylene (FEP). This is a fully shielded design from column to column for minimal signal interference.

Overview

Data centers are expected to deliver ever-faster data rates. However, as speeds increase, degraded signal integrity performance becomes an issue. The Impulse Backplane Connector System targets 56 or 112 Gbps (PAM-4) rates while delivering optimal signal integrity by eliminating the need for a mid-plane connection. Additionally, an innovative signal interface improves insertion loss over traditional beams, pushing interface resonances far beyond 30 GHz.

As data rates are expected to continue increasing, data centers look for scalability in equipment to minimize future infrastructure investments. Impulse Orthogonal Direct Backplane Connectors are forward compatible to meet future data rate requirements without the need to replace infrastructure.

Prototyping cable assemblies requires tooling. Therefore, the cost generated to prototype a system can be significant. Impulse Backplane Cable Assemblies solve tooling start-up costs by providing a completed assembly.

Once prototyping is complete, customers typically need to create drawings and assign resources to find a supplier to build cable assemblies for end products. Molex builds cable assemblies to provide one-source solutions.
