D-Link DEM-CB300QXS 40G QSFP+ 3M Direct Attach Cable

Keep Short 40G Links Simple with a Direct Copper Connection The DEM-CB300QXS connects compatible QSFP+ interfaces across a three-metre passive twinaxial cable. Integrated QSFP+ terminations provide a ready-made short-reach link without selecting separate optical transceivers and fibre jumpers. It is specified for compatible DXS-3600 installations, including the DXS-3600-16S and DXS-3600-32S when fitted with the DXS-3600-EM-4QXS module. Confirm the port support and link configuration at both ends before ordering. Highlights A Direct 40G Link QSFP+ connectors at both ends. Up to 40 Gbps over a fixed 3M cable. Designed for Short Runs Passive twinaxial copper construction. Suitable for a compatible within-rack or nearby-rack connection. Plan the Port and Route For compatible DXS-3600 QSFP+ interfaces. Minimum specified bend radius of 32 mm. Key Features Remove Separate Optical Components Both connectors are part of the cable assembly. For a supported short copper connection, there is no separate pair of optical transceivers or fibre patch leads to match, simplifying the bill of materials and the physical installation. Match the QSFP+ Interfaces Use it with compatible QSFP+ ports, including the DXS-3600-EM-4QXS in DXS-3600-16S and DXS-3600-32S hosts. Both ends are QSFP+; this is not a QSFP+ to SFP+ breakout cable and does not provide four separate SFP+ tails. Allow Room for the Cable The three-metre length gives a defined cable path for nearby equipment. Respect the 32 mm minimum bend radius and allow space around the terminations rather than forcing a tight bend directly behind the port. Verify the Link Configuration Check hardware support, port mode and firmware at both endpoints. Mechanical connector fit alone is not a promise of interoperability with every third-party switch or adapter. Summary The DEM-CB300QXS is a practical choice for a verified three-metre 40G QSFP+ link. Its integrated passive copper assembly keeps the connection straightforward when both endpoints support this exact cable and the planned route fits its length and bend requirements. Frequently Asked Questions What Connectors Are Fitted?ExpandCollapse There is a QSFP+ connector at each end. This is a straight QSFP+ to QSFP+ assembly, not a breakout cable. Which DXS-3600 Hosts Are Supported?ExpandCollapse The DXS-3600-16S and DXS-3600-32S use this cable through a compatible DXS-3600-EM-4QXS expansion module. Confirm the port configuration and host hardware/firmware. Do I Need Optical Transceivers?ExpandCollapse No separate optical transceivers are used for this supported direct copper link. The QSFP+ ends are integrated into the assembly. Can I Extend the Cable or Change Its Length?ExpandCollapse It is a fixed 3M assembly. Choose a different supported connection arrangement if the equipment route is longer; do not assume the cable can be extended with a passive coupler. Will It Work in Any QSFP+ Device?ExpandCollapse Check the exact device support list and port configuration. A matching connector shape does not establish third-party interoperability. What Warranty Is Included?ExpandCollapse The warranty for this offer is 1 year. Magbasa pa
