Polarization Maintaining Short Wavelength Fibers
Coherent's industry-leading visible and short wavelength Polarization Maintaining fibers have superior waveguide, radiation, and mechanical properties enabling a large variety of critical applications in diverse markets. High consistency and extreme end-to-end control of optical properties provide particular advantage in spectrographic and frequency-sensitive applications. The intrinsically high level of radiation resistance allows this family to operate for extended periods of time on low earth orbits, near and deep space, and in applications where risk of exposure to man-made radiation is great.

Zg-photonics
Passband wavelength range: Minimum:1260 nm;Maximum:1625 nm Stopband wavelength range: Minimum:1644.5 nm;Maximum:1655.5 nm Insertion Loss (1260nm ~ 1360nm) (IL) [1260nm ~ 1360nm; insertion loss IL (dB) = -10lg(output power/input power)(dB)]: Maximum:1.0 dB
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
Port Configuration: Fiber In,Free-space out Signal light wavelength: 800~2000 nm Input Fiber/Cladding Diameter: X/125 μm
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.
