-
Cost-Effective Solution: SFP+ connectors on both ends eliminate the need for costly transceivers
-
Lower Latency: Faster transmission speeds compared to CAT6/CAT6A 10GBASE-T cables
-
Short-Distance Optimised: 1-metre length perfect for in-rack or adjacent rack connections
-
Wide Compatibility: Certified for use with D-Link switches including DGS-1510, DGS-3420, DGS-3630, DXS-3400, and DXS-3600 series
Ideal for High-Bandwidth Data Centre Applications
The DEM-CB100S is engineered for demanding networking environments where high-speed data transmission and energy efficiency are critical. This 10G passive SFP+ cable supports connections for 10 Gigabit Ethernet switches with 10GbE uplinks, delivering performance much faster than standard SFP cables which only support 2.5 Gbps. The cable is ideal for highly cost-effective networking connectivity between switches and servers within a rack or in adjacent racks, making it perfect for Australian data centres, enterprise IT rooms, and high-performance computing environments.
Enhanced Small Form-Factor Pluggable Design
Featuring Enhanced Small Form-factor Pluggable (SFP+) connectors, the DEM-CB100S offers superior port density and lower power consumption compared to larger form factors like Xenpak, X2, and 10G XFP. The SFP+ format uses the same space-per-port as standard SFP connectors but supports significantly higher data transmission speeds. With 30 AWG wire gauge and 100 Ohms characteristic impedance, the cable maintains excellent signal integrity and minimal crosstalk for reliable performance.
Energy-Efficient Networking Solution
Compared to other 10G cable types such as 10GBASE-CX4 and CAT6/CAT6A 10GBASE-T, the DEM-CB100S offers lower power consumption and reduced latency, making it an optimal solution for handling high bandwidth transmission within short distances in energy-efficient data centres. The passive design requires no external power, further reducing operational costs and environmental impact.
Technical Specifications & Standards Compliance
The D-Link DEM-CB100S is fully compliant with industry standards including SFP MSA (Multi-Source Agreement), SFF-8431, EIA 364, and UL 94. It operates reliably in a wide temperature range from -40°C to 85°C, making it suitable for various networking environments. The cable features a minimum bend radius of 23.5mm and supports a VMA Loss to Crosstalk Ratio (VCR) of minimum 32.5 dB for superior signal quality.
