What is the difference between 100G AOC Active Optical Cable and 100G High Speed Cable?

Both 100G Active Optical Cable AOC and 100G High Speed Cable have the role of transmitting data. However, there are some differences between 100G AOC active fiber optic cable and 100G high speed cable.

What is 100G AOC active fiber optic cable?

100G AOC active fiber optic cable refers to the communication process requires the use of external energy, the electrical signal into optical signals, or optical signals into electrical signals communication cable, optical transceivers at both ends of the fiber optic cable to provide photoelectric conversion and optical transmission function, and the transmission rate reaches 100Gb/s. 100G AOC active fiber optic cables can be used to transmit data, but there are some differences between 100G AOC active fiber optic cable and 100G high speed cable.

What is 100G high speed cable?

100G high-speed cable adopts silver-plated conductor and foam insulated core, with excellent attenuation performance and low delay performance, so that the signal transmission is correct, but also can improve the transmission speed, is an alternative to the optical module of the short-distance connection solution, the price is much cheaper than the same type of optical module, in the short-distance connection applications have been widely welcomed.

Structure of 100G AOC Active Optical Cable

Simply understood, active optical cable consists of two optical transceivers and a fiber optic patch cord, and the fiber optic transceiver device and different lengths of OM3 or OM4 multimode fiber at both ends.

The structure of 100G high-speed cable

High-speed cable referred to as DAC, both ends and switches or servers are connected to achieve short-distance transmission, high-speed cable can be divided into two categories of passive high-speed cable and active high-speed cable, active high-speed cable is just more than passive high-speed cable with a driver chip. High-speed cable above the "optical module" are not the true meaning of the optical module, they are not with the component, only the transmission of electrical signals, so high-speed cable is cheaper than other common optical devices, even if you use the same port as the optical module interface, high-speed cable in short-distance applications, but also can effectively save costs and reduce power consumption, this is why people choose high-speed cable, high-speed cable can be divided into two categories of passive and active high-speed cable, active high-speed cable is just more than passive high-speed cable a driver chip. This is why people choose high-speed cables.

Classification of 100G AOC Active Optical Cables

There are two types of 100G AOC: 100G QSFP28 Active Optical Cable AOC and 100G QSFP28 to 4X 25G SFP28 Active Optical Cable; the former has an optical module receiver at both ends; it realizes one-to-one transmission; the latter has a 100G QSFP28 interface at one end and four 25GSFP28 interfaces at the other end, which can provide customers with 100G data transmission.

Classification of 100G high-speed cables

There are two types of 100G high-speed cables: 100G QSFP28 DAC direct-connect cable and 100GE QSFP28 to 25G SFP28 DAC direct-connect cable; the former has an optical module receiver at both ends; it realizes one-to-one transmission; the latter has a 100G QSFP28 interface at one end and four 25GSFP28 interfaces at the other end, which can provide 100G data transmission for the customers. data transmission.

It is important to note here: although the classification of the two is not very different, but the optical transceiver of the active fiber optic cable is built-in laser, while the high-speed cable module is no internal laser.
