Big data has penetrated into every aspect of everyone's life, so the importance of high-speed and high bandwidth is self-evident. The carrying of data requires more data centers to complete, so AOC active optical cables, the carrier of the high-speed interconnection of data centers, appeared.
AOC optical module, AOC active optical cables, the two are expressed as the same item. Active Optical Cables is the full name of AOC.
AOC active optical cables refer to communication cables that need to convert electrical signals into optical signals, or convert optical signals into electrical signals during the communication process. The optical modules at both ends of the optical cable provide photoelectric conversion and optical transmission functions. We also have sfp28 dac cable for sale.
As a responsible active optical cables supplier, we are pleased to share with you the composition of AOC. Its structure is very simple. In simple terms, two optical modules are connected by an optical cable, that is, the middle is an optical fiber cable, and the two ends are optical cables.
But in other words, it's expensive for a reason. The optical port is not exposed to ensure airtightness. AOC active optical cables will not have unexpected problems due to special environments. When faults occur, they can be easily checked, so that the DDM function can be eliminated, thereby further optimizing the cost.
AOC optical module, optical module and optical fiber are integrated and cannot be separated. The optical cable transportation is much more reliable than the copper cable, the information can be guaranteed. And the working distance of AOC optical module is also greatly extended, reaching the common 100-meter model now.
The optical fiber is fixed in the optical module, so that less optical components can be installed, so the cost is reduced. Of course, the price of optical cables cannot be ignored, so the most suitable scene for AOC active optical cables is still in the IDC data center room. And we have different fiber optic transceiver types.
Compared with other cables, AOC active optical cables have high transmission rate, long distance, low power consumption, low weight, easy to use and so on. The fundamental reason why so many advantages can be achieved is that the mode of optical transmission is adopted.
Because it is optical transmission, some fatal limitations of passive optical cables or other cables can be solved by optical components or electronic components embedded in the connector. And because of this, there is less and less copper technology in today's data centers and high-performance computing (HPC) applications.
After all, passive optical cables or other cables have the disadvantages of heavy weight and large volume. In data centers where space is expensive, this obviously cannot meet the requirements of high density, especially electrical signals are more likely to be affected by electromagnetic waves. Interference (EMI), which seriously slows down the speed and increases packet loss.
At present, 400G AOC and 200G AOC have appeared in the optical module market. And 10G SFP+ AOC active branch cable, 40G QSFP+ AOC active branch cable, QSFP+ to 4 SFP+ AOC active branch cable are already relatively stable products.
In general, the wired transmission of optical communication refers to the passive part. But there are exceptions, such as active optical cables. Active optical cables are composed of multimode optical fibers, optical transceivers, control chips and parallel optical modules.
The optical transceivers at the head and tail of the active optical cables have photoelectric conversion and optical transmission functions, which can be used to improve the transmission speed and transmission distance of the optical cable. At the same time, the AOC active optical cables will not weaken the compatibility with standard electrical interfaces.
Equipment manufacturers of optical modules will encrypt their devices to varying degrees, also known as compatibility. Modules of a particular brand can only be used with devices of the same brand, and cannot be matched with other brand optical modules. Compatibility manufacturers need to conduct different compatibility adaptations on the optical modules. Whether or not they can perfectly solve compatibility issues is particularly important.
