3m 10 Gigabit SFP+ DAC Cable - Passive Copper Twinax for Adjacent Racks

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.

The 3m length represents the practical maximum distance for a passive copper DAC cable to maintain reliable signal integrity at 10Gbps making it the longest distance possible while retaining the cost and power benefits of passive copper . It is specifically designed for connecting equipment located across 2 or 3 adjacent server racks in the same row.

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.
• Maximum Passive Reach: The longest available length for passive DAC ideal for spanning 2-3 racks in a row.
• 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

• Connecting a core switch to a distant server or storage unit within a home network closet setup.
• Providing necessary slack for highly complex cable routing within and between two cabinets.
• Connecting high-performance NAS (Network Attached Storage) units across a room.
• Perfect for low-latency links required for high-speed data backups and gaming.

Office and Professional Use

• **In-Row Linking:** The maximum reach solution for connecting devices located across up to three neighbouring server racks.
• **Inter-Switch Link:** Connecting core aggregation switches that are separated for redundancy purposes.
• **SAN/Storage:** Connecting storage area networks (SAN) at the maximum passive copper distance.
• **Data Centres:** Maximizing the copper link distance to save on fibre hardware costs.

Educational Use

• Connecting servers and switches across several adjacent racks in lab environments.
• Teaching networking students about the distance limitations and benefits of copper DAC.
• Providing long high-bandwidth links for campus network backbones.
• Cost-effective solution for linking networking gear in training rooms.

Dimensions

• Cable Length: 3 metres (300 cm)

Summary

A 3-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 devices located across multiple adjacent racks providing the maximum distance for passive copper DAC.
