As a cost-effective high-speed data communication solution that replaces optical modules, high-speed cables are widely used in storage area networks, data centers, and high-performance computer connections. In this blog, ETU-LINK will introduce high-speed cables.

High-speed cable (Direct Attach Cable, referred to as DAC) is a kind of cable assembly purchased in a fixed length with fixed connectors at both ends, used for interconnection between short-distance devices. The connectors used for the high-speed cable are the same as optical modules. However, compared with optical modules, the connector modules of high-speed cables do not have expensive optical lasers and other electronic components, thus greatly saving costs and power consumption in short-distance applications. Generally, if the transmission distance is less than 7M, it is recommended to use high-speed cables, which are more cost-effective. Otherwise, AOC active optical cables or optical modules are more preferred.

Advantages of high-speed cables

High performance: The product’s maximum rate up to 200Gbps.

Good heat dissipation: The internal material of the cable is copper core. The natural heat dissipation effect of copper cable is good, energy saving and environmental protection.

Low crosstalk: Magnetic field interference has little impact on high-speed data transmission by DAC.

Low power consumption: Divided into active and passive. Passive cables do not require power and consume almost 0 power.

Low cost: Copper cables are cheaper than fiber optics, so using high-speed cables will reduce cabling costs.

ETU-LINK can provide high-speed cables with data transmission rates from 1Gbps to 200Gbps to meet the growing cabling needs for high-speed transmission, scalability and reliability.
