87128-4 is a communications network standard set forth by the International Telecommunications Union (ITU) that defines the physical characteristics of a broadband optical network connection such as the types of cables to use, cable lengths, and the signal frequencies. This standard has many applications in a variety of fields.

One of the most common applications for 87128-4 is in the field of telecommunications. The standards specified by 87128-4 are an integral part of the implementation of wireless communications technology such as LTE and WiMAX. This allows for a variety of devices to communicate with each other over a wireless network utilizing different frequencies and signal strengths.

In addition to telecommunications, 87128-4 is also widely used for a number of industrial applications. The standards set forth by 87128-4 can be used to facilitate the movement of data between different pieces of equipment. This helps reduce the cost of operation of a manufacturing plant by streamlining the system and increasing efficiency. Additionally, 87128-4 helps create a secure and reliable communications network for a variety of industries that need consistent and secure transmission of data and voice traffic.

The working principle of 87128-4 begins with the physical connections between devices. Devices that are to be connected must be soldered to an optical cable that meets the 87128-4 standards. Cables may be single mode or multimode, depending on the needs of the application. Once they are connected, the devices must use a protocol to exchange data between them. This is done over the frequency band specified in the 87128-4 standard.

The principles of 87128-4 do not stop at the physical connections and protocols, but also include the necessary steps for ensuring the secure transmission of data. Through the use of encryption standards, such as Advanced Encryption Standard (AES) and Elliptic Curve Cryptography (ECC), devices are able to securely exchange data without the risk of it being accessed by third parties. Additionally, the 87128-4 standard includes protocols for authentication and authorization to ensure that only authorized users have access to the network.

In summary, the 87128-4 standard is used across many different industries and for a variety of applications. It is an important part of the implementation of wireless communications, and it also helps reduce costs and ensure the secure transmission of data. The working principle of 87128-4 involves connecting devices to a cable that meets the standards of 87128-4, and using protocols to exchange data securely over a frequency band. Additionally, it includes protocols for authentication and authorization to ensure the secure transmission of data.
