Infiniband & SFP+ SDR / DDR / QDR Cables

Channel Matrix II Cable Features

• True Cabled Design for Greater Flexibility
• Dimensions Compatible with QSFP & CX4 Connectors
• Heat Bonded Tapes for Channel Isolation
• Attenuation "suckout" Outside of 10 Ghz

Channel Matrix II Cable Description

Basic construction of these Infiniband cables consists of 8 parallel-pairs cabled round. An overall AL/PET tape and braid shield are electrically isolated from the transmission pairs. A flexible PVC jacket completes the design.

Channel Matrix II Cable Applications

• Infiniband Architecture - SDR (Single Data Rate), DDR (Double Data Rate) and QDR (Quad Data Rate)
• Low Skew Applications
• Differential Pair Applications
• PCI Express
• CX4 10 GB Ethernet Applications

Bulk Infiniband Cable RoHS Eco-Friendly Index

Hitachi Cable Manchester is making every effort to provide Lead free and Cadmium free products to help protect our environment. To this end Hitachi Cable Manchester, Inc. has adopted RoHS (Restriction of Hazardous Substances) as its standard. Hitachi's website Eco-Index is designed to inform the interested user of contents of various restricted or banned elements in terms of parts per million. In most cases, the numbers stated are from actual lab tests using the acid digestion method, considered to be the most severe measurement of analyzing content of restricted and banned elements. It is Hitachi's goal to be 100% compliant to European RoHS, including the removal of the Deca-BDE exemption dated July 1, 2008. This cable is REACH Compliant.
