NGC（MIL-DTL-64266） Fiber Optic Connector-Aviation Connector

The NGC series fiber optic connectors minimize insertion loss, effectively reducing optical signal attenuation during the connection process and ensuring efficient transmission. NGC connectors offer excellent return loss performance and strong suppression of link optical power reflections, significantly reducing optical signal reflections and interference, thereby improving transmission quality. NGC connectors also offer excellent interchangeability and reusability. Connectors of the same type can be used in any combination and repeatedly plugged and unplugged with minimal additional loss, ensuring the long-term stability and reliability of fiber optic networks. The NGC connectors' robust mechanical structure withstands repeated plugging and unplugging and varying environmental conditions, resulting in a long service life and reduced maintenance and replacement frequency. NGC connectors exhibit excellent anti-interference performance, effectively preventing electromagnetic interference and lightning interference, and operating stably in complex electromagnetic environments.

The NGC series fiber optic connectors are primarily used in the military. In the air, they are used in naval aircraft communication, navigation, radar, and other systems, ensuring stable optical signal transmission during flight. They are also used in shipboard communication systems and sonar detection equipment, ensuring high-speed, reliable data transmission in complex marine environments. In space military applications, NGC connectors can connect the measurement, control, communication, and data transmission systems of satellites, spacecraft, and other spacecraft, meeting the stringent requirements of the space environment. Furthermore, NGC connectors also have a certain scope of application in certain high-end civilian applications that require extremely high connector performance, such as connecting core network equipment in high-speed data centers and long-distance trunk optical communication systems.
