There are mainly three types of DAC/AOC: Passive copper cable, active copper cable and active optical cable. AOC is composed of integrated optoelectronic devices, which is used for high-speed and high-reliability transmission equipment between data centers and other equipment, and uses the advantages of optical cable for data transmission. In the data center, the DAC cable is most commonly used, and it has become the best solution to achieve short-distance transmission. DAC‘ s applications are generally on optical switches, such as LY2 switches.

Primus It has been working to solve the bottleneck problem of network bandwidth opticalmodules through continuous technological innovation, adheres to concentrate superior forces constantlyimprove the industrial layout. Meanwhile, Primus lT' s AOC factoryand DAC factorywill continue to invest to increase R &D efforts, and actively manufacturing good and cheap high speed dac.

DAC uses overview

DAC (Direct Attach Cable) is a non-replaceable port, and the module head and copper cable cannot be separated. In data centers, copper cables are commonly used to connect servers to storage area networks. Direct copper cables are most commonly used, and passive copper cables are especially used. Passive copper cable is the best solution for short-distance transmission because of its cheap price and fast transmission speed.

Primus IT product line covers high-speed copper cable (DAC) components and high-speed active optical cables (AOC) and active optical fiber , which can achieve stable performance and efficient connection.

Advantages of direct attach cable DAC material

The advantages of direct attach cable(DAC) and have become the first choice for users in short-distance application scenarios, and are widely used in data center interconnection scenarios such as SATA storage devices, RADI system scenarios, core routers, 10G or 40G Ethernet, etc.

DAC functions in various industries

Audio Amplification and Video coding

DAC is used to generate DC voltage gain through microcontroller commands. Typically, DAC will be integrated into the entire audio codec that includes signal processing capabilities. The video encoder system processes video signals and sends digital signals to various DAC to produce analog video signals in various formats, these IC may have integrated DAC.

Data acquisition and distribution system

Data acquisition includes a process control terminal, in which the processor sends feedback data to DAC to convert it into an analog signal. The data to be measured is digitized by an analog-to-digital converter (ADC) and then sent to the processor. Many industrial and factory production lines require multiple programmable voltage sources, and the use of DAC allows the voltage to be changed dynamically during system operation.

Digital potentiometer and display electronics

Almost all digital potentiometers are based on serial DAC architecture. By reorganizing the resistor/ switch array and adding an I2C compatible interface, the all-digital potentiometer can be realized. The graphics controller usually uses a look-up table to generate data signals sent to the video DAC for analog output, such as signals of different colors, to drive the display.

Fiber dac cable is used in conjunction with a digital signal processor (DSP) to convert a signal into an analog signal, which is transmitted in a mixer circuit and then to a radio power amplifier and transmitter.



What is AOC?


Active Optical Cable, AOC is composed of integrated optoelectronic devices, which are transmitted through internal electrical-optical-electrical conversion.


What is DAC?


Direct Attach Cable, This kind of cable cannot replace the port, and the module head and the copper cable cannot be separated.
