ERmet ZD
Cable System
General
ERmet ZD Cable Assemblies allow high speed digital signals to be
transmitted further and with superior signal fidelity. This connector
system has been optimized to transmit high speed differential signals
between 2.5 to 10 Gigabits per second. ERmet ZD Cable Assemblies
come in a variety of different cable sizes, custom pin-out configurations,
and are available in either cable or backplane header compatible ver-
sions. EMI backshells can also be incorporated to provide a complete
interconnect solution for external cabling requirements.
This modular interconnect product family has been designated
a common platform for interoperability testing by the 10 Gigabit Ethernet
Alliance XAUI Interoperability Group and 10 Gigabit Ethernet
Consortium. The connector has also been selected as the backplane
interconnect for the PICMG 3.X (ATCA) industry standard.
Features
• Low loss, low crosstalk, low skew
• Controlled impedance through connector
• Optimized grid design for enhanced electrical performance and trace
routing
• Integrated polarization, guidance and mechanical latching
• Available versions:
- 4 pair cable header with latch for 5 wafer cable system
- 4 pair cable header without latch for 5 wafer cable system
- 4 pair backplane connector for 10 wafer cable system
• 2 pair versions available on request
