QSFP+, Passive Copper Cable 30AWG to 4xSFP+, CR4 40G, 1m, MSA Compatible

Overview

This QSFP+ to 4xSFP+ passive copper breakout cable is designed for high-speed interconnects, providing an efficient 40Gbps link between QSFP+ ports and four individual SFP+ ports. Using 30AWG copper cabling, this solution supports short-reach data center applications, including server-to-switch connectivity and high-density network rack configurations.

The cable is fully MSA (Multi-Source Agreement) compliant, ensuring interoperability across a wide range of networking equipment. Passive copper construction offers a low-latency, power-efficient alternative to active optical solutions for short-range deployments.

Key Features

• High-Speed Connectivity
  Supports 40Gbps data throughput for demanding network environments.
• Breakout Configuration

• Data center server-to-switch interconnects
• High-density rack networking
• Storage area networks (SAN)
• Network Interface Card (NIC) to switch uplinks

Technical Specifications

Frequently Asked Questions

What is the maximum reach of this passive cable?
This cable is optimized for short-reach applications, typically up to 1-3 meters depending on the specific equipment and signal requirements.

Does this cable require any external power?
No, as a passive direct attach copper (DAC) cable, it draws negligible power directly from the host ports.

Is this compatible with all switch brands?
This cable is MSA compliant, which generally ensures compatibility with major networking equipment vendors; however, we recommend verifying specific host port requirements.

Can I use this for 10G connections?
Yes, this cable breaks out a 40G QSFP+ port into four individual 10G SFP+ channels.

Is it hot-pluggable?
Yes, the connectors support hot-swapping for convenient maintenance without powering down the host devices.
