Structure and advantages of high-speed DAC cable


 High-speed cable (DAC), as a low-cost short-distance connection alternative to optical modules, is widely used in SATA storage devices, RADI system scenarios, core routers, 10G or 40G Ethernet data center interconnection scenarios.


Structure of High Speed Cables


Silver-plated conductors and foamed insulated core wires are used as materials to form high-speed cables by means of line-to-line shielding and total shielding. High-speed cables have excellent attenuation performance, low delay and anti-interference. They can realize high-frequency broadband transmission. They have 30-24AWG specifications and 2P, 4P or 8P structures. They can be used in many different applications.

C-FLINK High Speed Cable Classification:

1、10G SFP+ to SFP+ DAC

2、25G SFP28 to SFP28 DAC

3、40G QSFP+ to QSFP+ DAC

4、40G QSFP+ to 4xSFP+ DAC

5、100G QSFP28 to QSFP28 DAC

6、100G QSFP28 to 4xSFP28 DAC


Advantages of the DAC cable:

1, High performance: It is suitable for short-distance wiring in data centers, with a wide range of applications and strong integration of integrated solutions.

2, Energy saving and environmental protection: The internal material of high-speed cable is copper core, and the natural heat dissipation effect of copper cable is good, energy saving and environmental protection.

3, Low power consumption: High speed cable power consumption is low. Since the passive cable does not require a power supply; the power consumption of the active cable is generally around 440mW.

4, Low cost: Copper prices are much lower than fiber optics, and the use of high-speed cables can significantly reduce cabling costs across the data center.

Direct Attach Cable

The advantages of high-speed cables have become the preferred solution for users in short-distance application scenarios. They are widely used in data center interconnection scenarios such as SATA storage devices, RADI system scenarios, core routers, 10G or 40G ethernet. High-speed cables supplied by C-FLINK will gradually become the preferred supplier of users through a number of checks and verifications before they leave the factory and with high-quality services.
