Product details

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. Features Connectivity QSFP+ (Quad Enhanced Small Form-factor Pluggable) 40 Gbps Gigabit Ethernet Fully Compliant with the following standards: SFP MSA (Multi-Source Agreement) EIA 364 UL 94 SFF-8436 SFF-8431 EIA-364-1000.01 Technical Specifications General Device Rate 40 Gbps Gigabit Ethernet Connector Type QSFP+ Cable Assembly Cable Length 3 metres Wire AWG 30 AWG Physical Minimum Cable Bend Radius 32 mm (1.26 inches) Cable Characteristic Impedance 100 Ohms Voltage 30 V AC Current 0.5 A Temperature Operating: -40 to 85 °C (-40 to 185 °F) Certifications SFP MSA (Multi-Source Agreement) EIA-364-1000.01 SFF-8436 EIA 364 UL 94 SFF-8431 For more information on our business-class solution, reseller pricing, distribution availability, and partner program please reach out to our commercial sales team at 888-354-6574 or solutions@us.dlink.com
