With the rapid development of AI servers, cloud computing data centers, high-performance computing (HPC), and high-speed switches, 400G high-speed interconnection has become an important part of modern network infrastructure. The use of high-speed DAC (Direct Attach Cable, direct copper cable) within server racks and between adjacent devices can balance transmission performance, low latency, low power consumption, and cost advantages, making it the preferred solution for many equipment manufacturers. Amphenol Cables on Demand SF-NDVVYF0004-001.5M is a passive high-speed copper cable component for 400G high-speed interconnection applications, suitable for short-distance high-speed data transmission, providing a stable and reliable high-speed connection solution for switches, servers, storage devices, and more. Public information shows that this product uses an OSFP interface, 30AWG high-speed Twinax cable, and a length of 1.5 meters, conforms to the OSFP MSA specification, and supports 400G high-speed interconnection applications.

Product Features and Typical Applications
SF-NDVVYF0004-001.5M belongs to the **OSFP Passive DAC (Passive Direct Attach Copper Cable)** product, both ends use OSFP interfaces, mainly used for short-distance high-speed interconnection between devices.
Its main characteristics include:
Supports 400G high-speed network interconnection;
* OSFP interface design, in compliance with industry MSA standards;
* Use 30AWG high-speed twinax shielded cable;
* Length of 1.5 meters, suitable for deployment inside and adjacent to cabinets;
Passive structure, no additional power supply required, lower power consumption.
Excellent shielding performance helps reduce crosstalk and electromagnetic interference.
Supports high-speed data center, AI server cluster, and high-performance computing platform deployment. ([RX Electronics][2])
Typical applications include:
AI GPU server interconnection
* Data Center Top-of-Rack (ToR) Switch
Spine-Leaf network architecture
Cloud computing server cluster
* HPC High-Performance Computing Platform
Enterprise-level high-speed storage network
Since DAC cables do not require an optical module, the overall cost is usually lower than that of AOC active optical cables and optical module solutions, making them highly cost-effective in high-speed interconnection scenarios within 3 meters.

Two, selection and compatibility reference and suggestions for alternative solutions
When selecting 400G OSFP DAC high-speed cables, it is recommended to focus on the following aspects:
Interface type
Confirm whether all device interfaces are OSFP interfaces to avoid mixing with different standards such as QSFP-DD, QSFP112, etc.
② Transmission Distance
DAC is usually suitable for short-distance interconnections of about 1 to 3 meters.
For longer distance deployment, consider:
* Active Optical Cable
* Optic module + fiber optic jumper solution
Rule for wire (AWG)
The wire gauge directly affects the transmission distance and flexibility.
For example:
* 30AWG: suitable for about 1~2 meters
* 28AWG: Suitable for longer distances
Thicker gauge wires usually have lower insertion loss, but larger bending radius.
Does it conform to the MSA standard?
It is recommended to choose products that comply with the OSFP MSA specification to ensure better compatibility between switches, servers, and network devices.
⑤ Domestic compatibility and substitution recommendations
For enterprises that need to reduce procurement costs, optimize delivery cycles, or enhance supply chain stability, they can choose domestic compatible solutions with high-speed DAC development capabilities. The following indicators are recommended for focusing on when considering domestic substitute products:
* Dimensions are compatible with the original model;
Interface definitions are consistent, can be directly replaced and installed.
* Meet the 400G high-speed transmission performance requirements;
Impedance control, insertion loss, and return loss meet industry standards.
* EEPROM information can be configured for compatibility with customer equipment.
* Support brand switch and server platform compatibility testing;
Available for different lengths, line specifications, and label customization services according to project requirements.
For the construction of new data centers, AI computing centers, and batch project procurement, domestic compatible solutions can not only meet the needs of high-speed interconnection, but also effectively reduce the overall procurement cost and improve delivery efficiency.

As an OSFP passive DAC cable designed for 400G high-speed network interconnection applications, Amphenol Cables on Demand SF-NDVVYF0004-001.5M combines features of high speed, low power consumption, low latency, and high reliability, suitable for various application scenarios such as AI servers, data centers, high-performance computing, and enterprise-level networks. During the project implementation process, it is recommended to conduct a comprehensive selection based on interface standards, transmission distance, cable specifications, compatibility, and maintenance requirements. At the same time, for users who aim to achieve supply chain diversification, control procurement costs, and ensure long-term supply stability, domestically produced alternative solutions with mature performance and reliable compatibility are also worthy of special attention.
