D-Link DEM-CB Series 10G SFP+ Direct Attach Cable

A Simpler Short-Distance 10GbE Connection The DEM-CB SFP+ direct attach cable series connects supported 10GbE equipment through a factory-terminated passive copper assembly. SFP+ connectors at both ends remove the need to buy separate optical modules and fibre leads for a short link between switches, servers or storage equipment. Choose the factory length that suits the rack route and confirm support on both connected devices. This is a copper DAC rather than an RJ-45 patch lead, optical cable or universal converter. The host model, firmware and cable compatibility remain part of the specification. Highlights 10GbE Connection Passive twinaxial copper assembly. Integrated SFP+ connectors at both ends. Choose the required factory length from the selector. Practical Installation For compatible switch, server and storage ports. No separate optical modules required for this cable connection. Confirm cable support at both ends before deployment. Rack Planning Select a length with room for routing and service access. Cable gauge and operating limits can depend on length and revision. 5-year warranty. Key Features An Integrated Short Copper Link Both SFP+ connectors are permanently part of the cable assembly. For a supported short rack connection, this avoids selecting two optical modules and a separate fibre patch lead. It does not convert an RJ-45 port or give a device 10GbE support that its network interface does not already provide. Choose Length From the Actual Route Measure the path through cable management rather than the straight-line gap between ports. Select a factory length that allows a comfortable bend and access for maintenance, without leaving excessive cable under tension. A suitable length keeps the connection tidy and leaves room for maintenance. Confirm Both Endpoint Models Check the exact switch or adapter model, firmware and supported DAC list. A cable that fits an SFP+ socket is not automatically accepted by every vendor or every port. Use the compatibility information for both devices, especially when the cable spans equipment from different manufacturers. 10GbE Without an Optical Patch Lead The assembly is intended for supported 10GbE copper direct attach connections. It does not use optical fibre and cannot be extended by adding LC fibre adapters. For longer routes or installations that need electrical isolation, specify a suitable optical module and fibre connection instead. Respect the Supplied Revision Conductor gauge, bend radius and environmental limits can vary with cable length or hardware revision. Check the supplied cable rating before using it in an unconditioned cabinet or a demanding industrial environment. Avoid tight bends and support the cable so its weight does not pull on the ports. An Orderly Rack Connection Label both ends, preserve connector access and check negotiated link speed and error counters during commissioning. Keep the cable away from pinch points and close the module latch properly. Follow the host manufacturer’s service instructions when inserting or removing a cable from powered network equipment. Summary The DEM-CB SFP+ DAC series offers a straightforward 10GbE connection for supported equipment over a short rack route. Select the appropriate factory length, check both host compatibility lists and allow for safe cable management. Frequently Asked Questions Does This Cable Need Separate Transceivers?ExpandCollapse No. The SFP+ connectors are integrated into the passive copper assembly, so separate optical modules and fibre leads are not used for this connection. How Do I Choose the Length?ExpandCollapse Measure the actual cable-management route and select the factory length shown in the selector. Allow space for bends and maintenance access. Will It Work With Any SFP+ Port?ExpandCollapse No universal compatibility is promised. Confirm that both exact devices and their firmware support the selected D-Link DAC. Is This a Fibre Cable?ExpandCollapse No. It is a passive twinaxial copper cable with SFP+ ends. It does not use LC connectors or optical fibre. Can It Be Used in an Industrial Cabinet?ExpandCollapse Confirm the supplied cable’s hardware-revision rating and the selected length before using it in an unconditioned environment. Industrial ratings should not be assumed from the connector type. Can It Increase a Slower Port to 10GbE?ExpandCollapse No. Both endpoints must already support the required 10GbE SFP+ connection and the selected cable. Magbasa pa
