The 40G Passive QSFP+ Direct Attach Cable is a high performance, high bandwidth and cost-effective connection solution that supports 40G Gigabit Ethernet. The 40G Passive QSFP+ Direct Attach Cable is designed to support high-density connections for switches with 40G interface, much faster than SFP+.
The DEM-CB300QXS-4XS QSFP+ to 4X SFP+ three-meter cable 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. The 40G Passive QSFP+ Direct Attach Cable is certified to be compatible with D-Link products to provide you best performance and reliability.
Ideal for High-Bandwidth Operations
The 40G Passive QSFP+ 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.
Quad Small Form-factor Pluggable Plus Format
The D-Link 40G Passive QSFP+ 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+.
Save on Costs
The D-Link 40G Passive QSFP+ Direct Attach Cable features QSFP+ connectors on both ends, thus eliminating the need for expensive QSFP+ transceivers. This makes it more cost-effective than fiber cables which must use QSFP+ transceivers.
