Product Features
Technical Overview
This DAC cable operates at 100 Gbit/s per the 100GBASE-CR4 standard, utilizing four lanes of 25 Gb/s to achieve full bandwidth. The twinaxial cable design provides robust electrical performance with low signal attenuation, supporting reliable data transmission over the 1-meter distance. The passive architecture means no active electronics are embedded in the cable, reducing power consumption and heat generation while maintaining signal integrity through copper conductors.
The QSFP28 connector features a compact, high-density interface that supports industry-standard latching mechanisms for secure connections. It is backward compatible with lower-speed QSFP+ environments when used with appropriate adapters or switches, though optimal performance is achieved at 100 Gb/s. The cable is tested for compliance with relevant IEEE and MSA specifications to ensure reliable operation in data center racks, server clusters, and network aggregation points.
Key Product Advantages
This cable offers a plug-and-play solution for short-reach connections within racks or between adjacent equipment, streamlining network upgrades and expansions. Its twinaxial construction ensures durable performance in data center environments with minimal maintenance requirements.
High-Speed Connectivity
Delivers 100 Gbit/s throughput using the 100GBASE-CR4 standard, ideal for bandwidth-intensive applications like data analytics, virtualization, and high-performance computing.
- Four 25 Gb/s lanes aggregate to 100 Gb/s
- Supports low-latency data transfer for real-time workloads
- Enables efficient backbone and spine-leaf network designs
Simplified Deployment
The passive DAC design eliminates the need for separate optical transceivers and fiber patch cables, reducing complexity and total cost of ownership.
- Integrated connector and cable assembly
- Hot-pluggable for easy installation and swaps
- Compatible with QSFP28 ports on switches, routers, and OEM modules
Deployment / Use Cases
This DAC cable is suited for environments where short-distance, high-speed connections are needed, such as within server racks, between network appliances, or in high-performance computing clusters. It supports OEM modules, switches, and routers from major vendors that implement QSFP28 interfaces, making it a versatile choice for heterogeneous network environments.
Typical applications include connecting leaf switches to spine switches in data centers, linking routers in service provider networks, or interfacing with specialized OEM hardware for telecommunications or financial trading. The 1-meter length is optimal for intra-rack cabling, minimizing clutter while ensuring reliable signal quality over copper.
Data Center Interconnects
Connect top-of-rack switches to servers or storage arrays within the same rack, providing high-bandwidth links for cloud infrastructure and virtualized environments.
Network Aggregation
Link core switches and routers in enterprise networks, supporting spine-leaf architectures and high-capacity backbones for campus or metro deployments.

FAQ
What is the maximum data transfer rate of this DAC cable?
This cable supports a data transfer rate of 100 Gbit/s, compliant with the 100GBASE-CR4 standard. It uses four lanes of 25 Gb/s each to achieve this throughput, making it suitable for high-bandwidth applications in data centers and enterprise networks.
What types of devices is this cable compatible with?
The cable is compatible with devices featuring QSFP28 ports, including OEM modules, switches, routers, and other network equipment. It is designed to work with a wide range of networking hardware from various vendors, provided they support the QSFP28 form factor and 100GBASE-CR4 electrical interface.
What does 'passive' mean for this DAC cable?
Passive indicates that the cable does not contain active electronic components like signal amplifiers or retimers. It relies on the electrical properties of the twinaxial copper conductors to transmit signals, which reduces power consumption, heat output, and cost compared to active DAC or optical cables, while maintaining performance over short distances like 1 meter.
What is the cable length and how is it measured?
The cable length is 1 meter, which is approximately 3.3 feet. This measurement includes the entire assembly from connector to connector, making it ideal for connections within a single rack or between closely positioned equipment in data center or network environments.
