3M 9QN0-114-22-1.00 DAC cable selection and domestic alternative

In data centers, high-performance computing, and high-speed network devices, high-speed interconnect cable components are an important basic component to ensure stable system operation. The 3M 9QN0-114-22-1.00, launched by 3M, belongs to the 9Q series high-speed DAC (Direct Attach Copper) cable assembly and is mainly used for high-speed connections between 100G QSFP28 interface devices. The product adopts a dual-axis copper cable structure and a high shielding design, which can achieve low-latency, high-bandwidth data transmission between servers, switches, and storage devices, and has important application value in modern data center interconnect architectures.

Product Overview of 3M 9QN0-114-22-1.00 Cable Assembly Component

3M 9QN0-114-22-1.00 is a QSFP28 to QSFP28 direct-attach copper cable assembly (DAC), belonging to the 3M 9Q series high-speed cable solution. Its core features include:

Interface Type: QSFP28 Plug-to-Plug Structure

Channel Structure: 4-channel high-speed transmission

• Maximum data rate: 100Gbps (4×25Gbps)

• Cable Type: Twin Axial

•  Wire gauge: 30AWG

• Length: 1.0m

• Shielding Structure: Full shielding design, reduces crosstalk and signal loss

•  Latching Method: Latch Lock clip structure, with Pull Tab

  Working temperature: 0℃ ~ 70℃

This type of DAC cable uses a high-flexibility dual-axis structure, which can be folded and routed internally within the rack to reduce air flow obstruction and improve heat dissipation efficiency. At the same time, it has a cost advantage over optical modules in short-distance high-speed interconnection scenarios. Its design usually complies with high-speed interface specifications and can be applied to data interconnection between servers, switches, storage arrays, and high-speed network devices.

Part Two: Selection, Compatibility, and Replacement Solutions Reference and Recommendations

In practical projects, the selection of high-speed DAC cables needs to focus on interface standards, cable length, transmission speed, and equipment compatibility. For 3M 9QN0-114-22-1.00, the selection and alternative solutions can be referred to the following points:

1 Interface standard compatibility

QSFP28 interface

  Adheres to the specifications of high-speed Ethernet and related high-speed communication protocols

  Suitable for 100G Ethernet server and switch connections

2. Length and ruler selection

• 1-meter length is suitable for short-distance interconnection within the cabinet

• If the distance is longer, you can choose 26AWG specifications or longer versions

3. Compatibility and Alternative Solutions Suggestions

In the actual supply chain environment, the original factory DAC cables may have long delivery times and higher prices, so it is advisable to consider domestic alternative solutions that meet the following conditions:

  Compatible with QSFP28 standard interface

  Support 100Gbps high-speed transmission

Adopt a dual-axis shielding structure to ensure signal integrity

  EEPROM information is compatible with mainstream switch recognition

  Offer custom-made with different lengths and line specifications

Through reasonable design and testing, domestic alternative DAC cables can achieve performance similar to that of original factory products in applications such as data centers, server clusters, and AI computing platforms, while also having certain advantages in cost control and delivery cycle.

The 3M 9QN0-114-22-1.00 QSFP28 DAC cable assembly is a high-performance cable product designed for 100G high-speed interconnect scenarios, featuring high bandwidth, low latency, flexible cabling, and stable shielding. It is suitable for high-speed connections between data center networks, high-performance servers, and storage devices. Against the backdrop of the continuous upgrading of high-speed network infrastructure, DAC cable solutions that combine performance and cost advantages are becoming an important choice for short-distance high-speed interconnects.
