QSFP28 100G to 4xSFP28 25G Direct Attached Cable 2 Meter

‌The QSFP28 to 4xSFP28 Direct Attach Copper (DAC) cable is a high-speed interconnect designed for data centers and networking environments that require robust performance. Here’s a breakdown of its specifications and features:

Specifications

Connector Types:

QSFP28: Quad Small Form-factor Pluggable 28; used on one end for connecting to 100G switches or routers.

4xSFP28: Four Small Form-factor Pluggable 28 connectors on the other end, each supporting 25G connections.

Data Rate:

Supports up to 100 Gbps on the QSFP28 side.

Each SFP28 side supports up to 25 Gbps, allowing for a total of 100 Gbps when using all four ports.

Length:

2 meters (approximately 6.6 feet), providing flexibility in equipment placement.

Cable Type:

Direct Attach Copper (DAC): A type of cable that uses copper wire for short-distance connections. It typically offers lower power consumption and cost compared to optical cables.

Applications:

Ideal for high-density connections in data centers, supporting applications like server-to-switch connectivity and inter-switch links.

Performance:

Low latency, high bandwidth, and efficient power usage.

Typically has a reach of up to 5-7 meters for copper cables, but is often used for shorter distances.

Features

Cost-Effective: Generally less expensive than optical cables, especially for short distances.

Easy Installation: Plug-and-play design simplifies deployment and maintenance.

Compatibility: Designed to work with equipment from various manufacturers as long as they adhere to the QSFP28 and SFP28 standards.

Robust Construction: Often built with a ruggedized design to withstand the rigors of data center environments.
