The JW8103A is a high-speed optical power meter specially designed by Shanghai Jiahui for optical communication R&D, production, and scientific research. It can be directly integrated into automated test and production systems, providing high-precision, multi-channel power measurement for the R&D and mass manufacturing of optical components and modules. An internal constant-temperature control circuit ensures the stability and accuracy of measurement data at the hardware level.

A grating filter is a passive optical device based on fiber Bragg grating (FBG, Fiber Bragg Grating) technology, which forms reflection or transmission characteristics at specific wavelengths in an optical fiber through periodic refractive index modulation. Its core function is to reflect signals at a specific wavelength (e.g., 1644.5nm~1655.5nm) while allowing signals at other wavelengths to pass through. It is widely used in wavelength management, optical path monitoring, and signal filtering scenarios in optical communication systems.

Lightel high-performance Fiber End Cap is used in highly specialized devices and equipment, including: high power fiber lasers, collimators and sealed PCF. The fiber end cap is made by splicing or laser fusing a short length of material to the fiber end face. In application scenarios, the fiber end cap allows the expansion of high power fiber laser beams to reduce the power density at the air/silica interface and protect the structural fiber from environmental influence.
