The DEM-CB100QXS-4XS QSFP+ to 4X SFP+ one-meter cable is designed to support high-density connections¹ for switches with 40G interface. DEM-CB100QXS-4XS features a QSFP+ connector on one end, and four SFP+ connectors on the other end, allowing it to connect to up to four 10G servers.

 

DEM-CB100QXS-4XS 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-CB100QXS-4XS features a QSFP+ connector on one end, and four SFP+ connectors on the other end, thus eliminating the need for expensive QSFP+ transceivers. This makes it more cost-effective than fiber cables which must use QSFP+ transceivers.
