D-Link 1m 25G Passive SFP28 Direct Attach Cable Black DEM-CB100S28

The D-Link DEM-CB100S28 is a 1 metre passive SFP28 Direct Attach Cable designed for high-speed 25 Gbps connections between compatible networking equipment. Ideal for short-distance in-rack links between servers and switches, it provides a cost-effective alternative to separate optical transceivers and fibre cabling where compatible SFP28 ports are positioned close together.

Key Features

• Passive SFP28 Direct Attach Cable for high-speed network connections.
• Supports data transmission rates up to 25 Gbps.
• 1 metre cable length suited to short-distance in-rack connections.
• SFP28 connectors provide direct connection between compatible 25G network interfaces.
• 30 AWG cable construction with 100 Ω characteristic impedance.
• Minimum cable bend radius of 23 mm.
• Wide -40°C to 75°C operating temperature range.
• Compliant with SFF-8402, SFF-8432, EIA-364, EIA-364-1000.01 and UL 94 standards.

High-Speed 25G Connectivity

The DEM-CB100S28 supports a data rate of up to 25 Gbps, providing the bandwidth required for data-intensive server and networking applications. SFP28 connectors at both ends enable a direct connection between compatible 25G interfaces.

Designed for Short-Distance Links

With its 1 metre length, the passive Direct Attach Cable is particularly suited to short-distance connections within a rack, such as linking compatible servers to switches. The direct copper cable assembly provides a practical option where the connected equipment is positioned close together.

Industry Standards Compliance

The DEM-CB100S28 complies with SFF-8402 and SFF-8432 SFP standards as well as EIA-364 and EIA-364-1000.01 electrical connector performance standards. It also meets the UL 94 flammability standard.

Compatibility

• Compatible network switches with supported 25G SFP28 interfaces
• Compatible servers and network adapters with supported 25G SFP28 interfaces
• Suitable for short-distance SFP28-to-SFP28 connections

Direct Attach Cable compatibility can depend on the network equipment manufacturer, interface configuration and supported transceiver or DAC list. Confirm that both connected devices support the DEM-CB100S28 or compatible passive SFP28 DACs before purchase.
