## Summary description

The Amphenol NDAQGJ-0002 is a passive Direct Attach Copper (DAC) cable designed for high-speed data transmission. It features a QSFP28 connector on one end and four SFP28 connectors on the other, supporting a total bandwidth of 100 Gigabits per second, split into 4x25 Gigabits. This 1-meter cable is ideal for connecting hardware within racks and between adjacent racks, ensuring reliable performance and minimal latency. Its durable construction and blue color make it a practical choice for data center environments.

## Long description

The Amphenol NDAQGJ-0002 QSFP28 to 4xSFP28 100G 1m Blue is a passive Direct Attach Copper (DAC) assembly designed for short-reach, high-bandwidth interconnects within data centers. With a QSFP28 connector on one end and four SFP28 connectors on the other, this 1‑meter cable carries a total of 100 Gbps as four independent 25 Gbps lanes. It is intended for connections between switches, servers, and storage devices in adjacent rack units or within the same rack, providing low latency and stable signal integrity in dense deployments.
Advantages
This DAC cable offers a cost-effective and power-efficient alternative to optical modules for short-distance links. The assembled QSFP28 to 4xSFP28 configuration simplifies port aggregation and breakout use cases while maintaining the full 100 Gbps aggregate bandwidth. Its passive design reduces heat and power consumption compared with active solutions. The 1 m length is suitable for top-of-rack and adjacent-rack cabling, and the blue jacket aids quick visual identification in cable runs.
Suitable for
 Top-of-rack switch to server connections
 Breakout of a 100G QSFP28 port to 4x25G SFP28 ports
 Adjacent rack interconnects and short patching
 High-density aggregation in server and storage bays
Key specifications
 Connector types: QSFP28 (one end) to 4 × SFP28 (other end)
 Aggregate bandwidth: 100 Gbps (4 × 25 Gbps lanes)
 Cable type: Passive Direct Attach Copper (DAC)
 Length: 1 meter
 Jacket color: Blue
 Typical use: Short-reach rack and adjacent-rack connections
How to use
Insert the QSFP28 connector into the 100G QSFP28 port on a compatible switch or adapter, and plug each SFP28 connector into the corresponding 25G SFP28 ports on target devices. Ensure connectors are aligned and fully seated to maintain signal integrity. Verify that connected devices support passive DAC breakouts and that port speeds and lane mapping are configured according to the host equipment documentation. Avoid sharp bends and excessive strain on the cable during installation.
Usage recommendations
Use this passive DAC for short-distance links up to 1 m inside racks or between adjacent racks. Confirm compatibility with switch and server vendor breakout modes before deployment. Route the cable to minimize bend radius and avoid interference from power cables to preserve signal quality.
