10 Gigabit SFP+ DAC Cable - Passive Copper Twinax Server Switch Link - 0.5m

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 0.5m length is ideal for connecting devices situated a few slots apart allowing for tidy organized vertical or horizontal routing within a single cabinet.

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.
• Optimal Routing: Perfect length for cross-connecting devices up to 8U apart in a rack.
• Reliability: Offers excellent signal integrity and reduced complexity compared to active components.
• Durable Jacket: Robust jacket protects the copper conductors suitable for demanding data centre environments.

Applications

Home Use

• Linking servers NAS units and switches within a home lab rack with clean short runs.
• Connecting vertically separated devices (e.g. a switch at 1U to a server at 8U).
• Achieving low latency for fast data backups and gaming setups.
• Ideal for tidily connecting devices in a small comms closet.

Office and Professional Use

• **In-Rack Linking:** Connecting servers to aggregation switches over short vertical distances within the same rack.
• **Top-of-Rack (ToR):** Linking equipment in the upper and middle sections of a rack.
• **SAN/Storage:** Connecting storage area networks (SAN) or high-speed storage arrays.
• **Cable Management:** Ideal for minimizing excess cable bulk while maintaining short-haul performance.

Educational Use

• Connecting networking gear vertically 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: 0.5 metre (50 cm)

Summary

A 0.5-metre Passive DAC Cable offering a cost-effective low-latency solution for 10 Gigabit Ethernet connectivity. This SFP+ to SFP+ copper link is ideal for connecting equipment separated by a few U-spaces within the same rack.
