Two, selection and compatibility and alternative solutions reference and suggestions

For high-speed DAC cables, it is recommended to focus on the following aspects:

Interface standard consistency

Ensure that the OSFP interface size, lock structure, and MSA specifications are consistent to ensure that the device can be inserted and removed normally and work stably.

Transmission speed requirements

Select data transmission specifications that support 400G based on equipment requirements, while ensuring high-speed signal integrity.

Cable Length Selection

SF-NDVVYF0004-001.5M is the 1.5-meter version, if the actual wiring distance is different, different length specifications such as 0.5m, 1m, 2m, 3m, etc. can be selected according to the cabinet layout.

4. Wire Gauge (AWG) Selection

Different lengths usually correspond to different AWG specifications. For short distances, 30AWG can be used, while for distances above 2 meters, it is usually recommended to use 26AWG or 28AWG to balance signal quality and transmission stability.

5. Compatibility verification

Domestic substitute products are recommended to support the OSFP MSA protocol and EEPROM compatibility configuration. Compatibility customization can be performed according to customer device brands (such as switches, servers, NIC network cards, etc.), improving system stability.

For users who wish to reduce procurement costs, shorten delivery cycles, or achieve domestic supply chain localization, they can choose a domestic DAC cable solution that meets OSFP standards, supports 400G transmission performance, and satisfies high-speed impedance control and signal consistency. Mature domestic substitute products can not only meet the daily deployment needs of data centers but also provide customized services such as cable length, cable specification, labeling, EEPROM coding, and brand compatibility according to customer project requirements, helping enterprises to build more stable, secure, and efficient high-speed interconnection solutions.
