Telecom relay is a general term for control relays used in electronic communication systems. The rapid development of the information industry has put forward higher and higher technical requirements for communication relays. The requirements of miniaturization, low power consumption and high reliability have become the inevitable development of electronic relays in the future trend.

At its core, a relay is an electromechanical or solid-state device that operates as a switch to control the flow of electrical currents. In the realm of telecom, relays are employed for various purposes, ranging from signal amplification to signal routing and protection.

One of the primary functions of relays in telecommunications is signal amplification. As signals traverse long distances, they often experience attenuation, resulting in a loss of strength. Relays are strategically placed along the communication path to amplify these signals, ensuring that they maintain their integrity and reach their destination with optimal strength.  This amplification process is essential for preserving the quality of voice and data transmissions in telecommunication networks.

Moreover, relays are integral to signal routing within telecom systems. They act as switches that determine the path signals take through the network. This routing capability enables efficient communication between different nodes and devices within the network. Relays help establish connections, redirect signals, and ensure that data reaches its intended destination accurately and swiftly.

Due to the particularity of the relay, the relay standards are also different due to the difference in the installed machine (switch). With the rapid development of communication equipment, the mounting board space is shrinking, and under the premise of not compromising performance, miniaturization has become an inevitable trend faced by every manufacturer.
