DEM-CB300QXS is designed to support high-density connections* for switches with 40G interface. The cable features two QSFP+ connectors, and is designed to support up to three meter connections.

 

The 40G Passive QSFP+ Twinaxial Direct Attach Cable supports speeds of up to 40 Gbps, while having lower crosstalk and power consumption than other cables. This makes it an optimal solution for handling high bandwidth transmission within short distances such as within a rack or between racks inside energy-efficient data centers.

 

The D-Link 40G Passive QSFP+ Twinaxial Direct Attach Cable uses Quad Small Form-factor Pluggable Plus format (QSFP+) connectors, which integrate four transmitting and four receiving channels. The QSFP+ cable assemblies can replace four standard SFP+ cable assemblies, resulting in higher port density, cost efficiency, and a reduction in power savings compared to standard SFP+.

 

DEM-CB300QXS features two QSFP+ connectors, thus eliminating the need for expensive QSFP+ transceivers. This makes it more cost-effective than fiber cables which must use QSFP+ transceivers.
