AOC is active optical cable, which is composed of optoelectronic devices (two optical transceivers and optical cable jumpers). Active optical cables are mainly used in data centers, high-performance computers, large-capacity storage and other equipment to carry out high-speed and reliable interconnection transmission equipment. The AOC application is an electrical interface that meets the requirements of industrial standards. It uses the internal electrical-optical-electric conversion of the optical cable to enable the optical cable to carry out efficient and stable data transmission.
DAC is a high-speed direct connection cable, which can also be called a direct connection copper cable. This type of cable port cannot be replaced, and the module head and the copper cable cannot be separated. Copper cables are the most common direct-connect cables for connecting servers and storage area networks in data centers. Direct-connected copper cables are divided into passive copper cables and active copper cables. Among them, passive copper cables are used more frequently. Because passive copper cables are affordable and fast, they provide the best solution for short-distance transmission. Program. DAC cables are usually used on switches in data center computer rooms, and both passive and active can be used.
