Main application: unidirectional transmission, blocking back light, protecting lasers and fiber amplifiers

Fiber optic gyroscope is the fiber angular velocity sensor, which is the most promising one among various fiber optic sensors. The fiber optic gyroscope, like the ring laser gyroscope, has the advantages of no mechanical moving parts, no warm-up time, insensitive acceleration, wide dynamic range, di......

The fiber cut-off wavelength is to ensure that only one mode exists in the fiber. One of the main transmission characteristics of single-mode fiber is the cut-off wavelength, which is of great significance for fiber optic cable manufacturers and users of fiber optic cables to design and use fiber o......

The transmission distance of the optical module refers to the distance over which the optical signal can be directly transmitted without relay amplification. It is divided into three types: short-distance, medium-distance, and long-distance. Generally speaking, 2km and below are short distances, 10-......

Optical fiber modules are components used to connect optical fiber cables to electronic devices. Optical fiber modules have many different parts, and different modules are designed to different specifications. Each part of the module is connected to a board that can be installed as a unit of elect......

Laser distance measuring is measured using a laser as a light source.It is divided into continuous laser and pulse laser according to the mode of laser operation.Gas lasers like helium-neon, argon ion, krypton cadmium and so on work in a continuous output state for phase laser ranging, dual heteroge......
