A fiber grating is a diffraction grating formed by axially modulating the refractive index of a fiber core by a certain method, and is a passive filter device. Because the grating fiber has the advantages of small size, small welding loss, full compatibility with fiber, and ability to embed smart materials, and its resonant wavelength is sensitive to changes in temperature, str...

According to the wavelength of the laser output wavelength, it is classified into S-band (1460~1530 nm), C-band (1530~1565 nm), and L-band (1565~1610 nm).

The working medium used in the fiber laser has the form of fiber, and the fiber laser characteristics are affected by the fiber conducting properties.

The function of the fiber collimator is to convert the light output from the fiber into collimated light (parallel light), or to couple external parallel light (approximately parallel) into the fiber for transmission, so that the maximum efficiency of light can be coupled into the desired device.

The wire sequence type or polarity of the MPO fiber patch cord is in the form of various line arrangements of the MPO pre-terminated fiber optic cable, the MPO distribution box, the MPO coupler in the standard document ANSI/TIA-568-C.3, and The 10/40/100G Ethernet multimode fiber transmission system interface format has a description.

The FP laser FP (Fabry-perot) laser is a semiconductor light-emitting device that emits multi-longitudinal mode coherent light with a FP cavity as a resonant cavity. FP lasers are mainly used for low-rate short-distance transmission. For example, the transmission distance is generally within 20 km, the speed is generally within 1.25 G, and the FP is divided into two wavelengths...

Fiber optic sensors are a new type of sensor that has evolved along with the development of fiber optic and fiber optic communication technologies. The fiber-optic sensor is corrosion-resistant, has little influence on the medium, and has strong anti-electromagnetic interference capability. Compared with the traditional sensors, the fiber-optic sensor uses light as a carrier fo...

Optical fiber test charts include: optical power meters, stable light sources, optical multimeters, optical time domain reflectometers (OTDRs), and optical fault locators. Optical power meter: Used to measure absolute optical power or relative loss of optical power through a length of fiber. In fiber optic systems, measuring optical power is essential. Much like the multimeter ...
