10 Gigabit SFP+ DAC Cable - Passive Copper Twinax Server Switch Link - 0.25m

This Direct Attach Copper (DAC) cable provides a highly reliable, cost-effective, and low-power solution for high-speed connectivity. Designed with SFP+ connectors on both ends, this cable allows you to connect network switches, servers, or storage devices (NAS/SAN) at 10 Gigabit Ethernet (10GbE) speeds over short distances.

As a Passive Copper cable, it consumes zero power itself and offers incredibly low latency, making it the preferred choice for linking equipment within the same rack. The ultra-short **0.25m** length is specifically designed for adjacent port-to-port connections, providing the neatest, shortest, and most efficient link possible.

Key Features

• High Speed: Supports 10 Gigabit Ethernet (10GbE) data transfer rates (SFF-8431 compliant).
• Connectors: SFP+ to SFP+ (Small Form-factor Pluggable Plus).
• Type: Passive Copper Twinax Cable, requiring no power consumption from the equipment ports.
• Low Latency: Copper construction ensures minimal signal delay, which is critical for high-speed storage and server applications.
• Cost-Effective: Provides a significantly cheaper solution than using two SFP+ transceivers and a separate fibre patch cable.
• Ultra-Short Length: Ideal for linking devices in directly adjacent slots or stacked switches.
• Reliability: Offers excellent signal integrity and reduced complexity compared to active components.
• Neat Cable Management: Reduces clutter and improves airflow by using the shortest possible link.

Applications

Home Use

• Linking two switches or devices stacked vertically in a home lab rack.
• Connecting a high-speed server to an adjacent patch panel or NIC.
• Achieving the absolute lowest latency for gaming or data backup.
• Perfect for small, shallow rack enclosures.

Office and Professional Use

• **In-Rack Linking:** Connecting adjacent Top-of-Rack (ToR) switches to each other.
• **Short Link:** Linking a server NIC directly to a nearby switch port in the same rack.
• **Cooling Optimization:** Optimising cooling and airflow in high-density data centre environments.
• The standard cable for adjacent in-rack connections.

Educational Use

• Connecting stacked networking gear in training rooms and university labs.
• Teaching networking students about short-haul data centre cabling solutions.
• Cost-effective solution for linking networking gear in training rooms.
• Minimising cable mess in educational server racks.

Dimensions

• Cable Length: 0.25 metre (25 cm)
