Fiber optic patch cables (Fiber Optic Patch Cables), also known as fiber optic connectors, refer to the installation of connector plugs at both ends of the optical cable to realize the active connection of the optical path. E2000-E2000 fiber optic jumpers have many advantages, such as: low insertion loss, high return loss, strong interchangeability and good repeatability. Both ends of the E2000-E2000 optical fiber jumper use E2000 connectors with spring valves and push-pull locking devices. The pull-lock device locks fully when you insert the connector in, and the spring-loaded valve closes automatically when you pull it out. This connector features protection of the pins from contamination and wear.
