D-Link DEM-CB300S 3 m Black Optical Cross Connect 10GbE SFP+ Direct Attach Cable
The D-Link DEM-CB300S is a high‑performance Direct Attach Copper (DAC) cable designed for 10 Gigabit Ethernet (10GbE) applications. With a length of exactly 3 meters, it provides an optimal balance between reach and signal integrity, making it ideal for data center interconnects, rack‑to‑rack connections, and stackable switch configurations.
Key Technical Specifications
- Connector Type: SFP+ (Male/Male)
- Maximum Data Rate: 10 Gbps
- Cable Length: 3 m (9.84 ft)
- Color: Black
- Construction: Twinaxial copper with aluminum shielding and a low‑profile design for tight rack spaces.
- Supported Platforms: Compatible with all SFP+ ports on D-Link switches, routers, and servers that support 10GbE DAC cables.
Design Features & Performance Benefits
The DEM-CB300S incorporates a robust shielding strategy to minimize electromagnetic interference (EMI) and crosstalk. Its twin‑axial design ensures that each pair of conductors is tightly coupled, which preserves signal integrity over the 3 m distance. The cable’s low profile allows it to be routed through narrow cable trays or directly between rack units without compromising airflow.
Because it is a direct attach solution, there are no active components such as optical transceivers or power supplies required. This eliminates additional points of failure and reduces overall system cost while maintaining the same performance characteristics as fiber optic links for short distances.
Ideal Use Cases
- Stacking Switches: Connect D-Link stackable switches (e.g., X-Stack series) to create a single logical device with increased bandwidth and simplified management.
- Rack‑to‑Rack Connectivity: Link adjacent racks in a data center for high‑speed inter‑rack traffic without the need for fiber cabling.
- Server Interconnects: Provide low‑latency, high‑throughput links between servers and storage arrays within the same rack or across close proximity.
Installation & Compatibility
Installing the DEM-CB300S is straightforward: insert each male SFP+ connector into the corresponding port on your devices. The cable’s symmetrical design ensures that either end can be connected to any compatible port, simplifying deployment and troubleshooting.
The cable is fully compliant with industry standards for 10GbE DAC links, guaranteeing interoperability across a wide range of networking equipment from various vendors. Its black color scheme blends seamlessly into standard data center environments, maintaining a clean aesthetic.
Packaging & Logistics
Each DEM-CB300S cable is individually packaged in a protective sleeve to prevent damage during transit. The product is shipped in cartons containing 10 units per case, with each case weighing approximately 4 kg (net weight 3 kg). This packaging configuration facilitates efficient inventory management and bulk ordering for large deployments.
Why Choose the D-Link DEM-CB300S?
- Reliability: Proven DAC technology with minimal signal loss over short distances.
- Simplicity: No active components required; plug‑and‑play installation.
- Cost‑Effective: Lower upfront and maintenance costs compared to fiber solutions for comparable reach.
- Versatility: Suitable for a wide range of networking scenarios, from small office setups to enterprise data centers.
The D-Link DEM-CB300S delivers dependable 10GbE connectivity in a compact, easy‑to‑deploy form factor. Its combination of performance, simplicity, and cost efficiency makes it an excellent choice for any organization looking to upgrade or expand its high‑speed network infrastructure.
