Product Description

QSFP+ Direct Attach Cable (QSFP+ DAC) is a cable solution for high-speed data communication, specifically designed to connect devices that support the QSFP+ (Quad Small Form-Factor Pluggable Plus) interface.

QSFP+ Direct Attach Cable uses copper wires as the signal transmission medium, usually using a twisted pair structure. It has a fixed length and is equipped with QSFP+ plugs at both ends for direct connection to devices that support the QSFP+ interface standard.

QSFP+ Direct Attach Cable provides high-bandwidth and low-latency data transmission capabilities, suitable for short-distance high-speed connection requirements. It has some advantages such as low cost, low power consumption and simplified configuration process. Compared with traditional optical modules and optical fibers, QSFP+ DAC can provide a more economical and simpler solution and reduce the number and complexity of components in the system.

QSFP+ Direct Attach Cable is used in scenarios such as data centers, enterprise networks, and high-performance computing. It is suitable for applications such as interconnection between servers, connections between network devices, and connections between storage devices and switches. Whether in applications such as large-scale data transmission, high-density server interconnection or high-speed network aggregation, QSFP+ DAC can provide reliable high-speed connections and meet bandwidth and performance requirements.

It should be noted that the transmission distance of QSFP+ DAC is usually short, generally between a few meters and more than ten meters. Therefore, when long-distance transmission requirements or higher rates are required, it may be necessary to consider using optical modules and optical fiber connections.

Product Application

For connections between servers within the data center, QSFP+ Direct Attach Cable can be used to achieve a high-density, high-bandwidth, and high-reliability network architecture, improving the operational efficiency and service quality of the data center.

For cross-machine room connections between data centers, QSFP+ Direct Attach Cable can be used to achieve long-distance optical fiber communication and ensure data synchronization and backup between data centers.

For connections between users of the cloud computing platform, QSFP+ Direct Attach Cable can be used to achieve rapid data exchange and sharing between users and support various cloud services and applications.
