Connector delivers data at 400Gbit/s sans EMI noise

Molex has designed a connector that transmits data at 400Gbit/s without compromising signal integrity and causing electromagnetic interference. The new zCD interconnect system will be released in short- and long-body versions to suit active copper or optical cables as well as transceivers.

Useful for next-generation devices in telecommunications as well as networking and enterprise computing, the zCD connectors feature a straight, back-route footprint with a 0.75mm pitch. An elastomeric gasket provides EMI containment and suppression. Designed to accept a broad range of thermal modules and heat sinks, the press-fit connector design ensures a robust and simple board termination.

zCD passive copper cable assemblies feature 32 pairs (16 channels) per I/O port at 25Gbit/s. A dual paddle-card system improves cross-talk performance through the cable interface. An embedded microcontroller cable-management interface allows custom host-management capabilities through a standard I2C bus. Compatible with 30 AWG Twinax cable, the passive copper bundle (up to 32 pairs) improves bend radius and flexibility in short-reach 400Gbit/s Ethernet or legacy and proprietary applications.
