Product Features
Technical Overview
This DAC cable operates at 40 Gbit/s per the 40GBASE-CR4 standard, utilizing twinaxial copper construction to deliver stable signal integrity over distances up to 3 meters. The QSFP+ connectors feature a compact, hot-pluggable form factor that supports high port density in modern networking hardware.
The passive architecture eliminates the need for signal conditioning electronics, reducing power consumption and heat generation while maintaining full 40GbE performance. This makes the cable suitable for environments where energy efficiency and thermal management are priorities.
Key Product Advantages
This cable offers several advantages for network infrastructure deployments. Its twinaxial construction provides robust electrical performance with lower latency compared to fiber alternatives for short distances, while the passive design ensures immediate compatibility without configuration overhead.
High-Density Connectivity
The QSFP+ connectors enable maximum port utilization in switches and routers, supporting scalable network architectures.
- Compact form factor
- Hot-pluggable design
- Supports high port counts
Cost-Effective Performance
Delivers 40GbE speeds at a lower total cost of ownership compared to active optical cables or separate transceivers.
- No external power required
- Reduced component count
- Lower per-port expense
Deployment / Use Cases
This DAC cable is optimized for interconnecting network devices within racks or between adjacent racks in data centers, enterprise server rooms, and high-performance computing environments. Its 3-meter length is ideal for top-of-rack switching configurations and short-distance spine-leaf architectures.
Common applications include connecting Alcatel switches to servers, linking switches in stacked configurations, and establishing high-speed links for storage area networks (SAN) or network-attached storage (NAS) systems. The cable's compatibility with standard QSFP+ ports ensures broad utility across modern 40GbE infrastructure.

FAQ
What is the maximum data transfer rate of this DAC cable?
This cable supports a maximum data transfer rate of 40 Gbit/s (40GbE) per the 40GBASE-CR4 standard. It is designed for high-speed network connections between compatible devices, providing full 40GbE performance over its 3-meter length without signal degradation.
What type of connectors does this cable use?
The cable features QSFP+ Network connectors on both ends. Each end has a single QSFP+ connector, making it a direct-attach solution for connecting two devices with QSFP+ ports. The connectors are hot-pluggable and support the high-density port configurations common in modern networking equipment.
What does 'passive' mean for this DAC cable?
Passive means the cable does not contain active signal conditioning electronics or require external power. It relies on the electrical properties of its twinaxial construction to transmit signals up to 3 meters. This results in simpler deployment, lower power consumption, and reduced heat generation compared to active cables.
What networking equipment is this cable compatible with?
This cable is designed for compatibility with Alcatel networking devices that feature QSFP+ ports. It supports standard 40GBASE-CR4 connections for network devices such as switches, routers, and servers. Always verify specific model compatibility with your equipment's documentation before deployment.
