Box Optronics 760nm 10mW butterfly laser utilizes a multi-quantum well distributed feedback (MQW-DFB) structure, ensuring a precise and stable 760nm wavelength with a narrow linewidth of less than 2MHz.

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, digital output, and small size. In addition, the fiber optic gyroscope also overcomes the fatal shortcomings of ring laser gyroscopes such as high cost and blocking phenomenon. Therefore, fiber optic gyroscopes are valued by many countries. Low-precision civilian fiber optic gyroscopes have been produced in small batches in Western Europe. It is estimated that in 1994, the sales of fiber optic gyroscopes in the American gyroscope market will reach 49%, and the cable gyroscope will take the second place (accounting for 35% of sales).

Randomly distributed feedback fiber laser based on Raman gain, its output spectrum has been confirmed to be wide and stable under different environmental conditions, and the lasing spectrum position and bandwidth of the half-open cavity DFB-RFL is the same as the added point feedback device The spectra are highly correlated. If the spectral characteristics of the point mirror (such as FBG) change with the external environment, the lasing spectrum of the fiber random laser will also change. Based on this principle, fiber random lasers can be used to realize ultra-long-distance point-sensing functions.

As the preferred pump source for EYDFA, the 976nm band precisely matches the absorption peak of erbium-ytterbium ions, offering high absorption efficiency and low thermal load. It can drive fiber lasers to output high-power lasers at 1030-1080nm, used in industrial processing scenarios such as laser cutting, welding, and cladding.

Optical fiber splice, which connects two optical fibers permanently or detachably, and has a splice part for protecting the components. The optical fiber splice is the end device of the optical fiber. The optical fiber connector is a physical interface used to connect an optical fiber cable. FC is the abbreviation of Ferrule Connector. The external reinforcement method is a metal sleeve and the fastening method is a turnbuckle. The ST connector is usually used for 10Base-F, and the SC connector is usually used for 100Base-FX.
