Lfiber’s large core fiber coupler (multimode fiber optic splitter: 100um, 105um, 200um, 300um, 400um, 600um, 800um, 900um, 1000um, 1500um (micron/μm)) is an optical power splitter designed to split light within ultraviolet, visible and infrared wavelengths, typically from 190 to 2500 nm. It bases on fused large core diameter optical fiber and features mode-insensitive & wavelength-insensitive over a broad wavelength range. We’ve homogenized the light and reduced the effects of higher order modes (by built-in cladding mode stripper). The split ratios do NOT fluctuate dramatically with the variation of wavelength and input beam mode. The coupler (splitter) is available for various core/cladding-diameter fiber, including 100/140, 105/125, 200/220, 200/230, 400/440 (400/430), 600/660 (600/630), 800/830, 800/880, 900/950, 1000/1100, 1500/1650, etc. This multimode large core fiber coupler (splitter) is an excellent choice for laser power delivery, sensors technology, optogenetics, biomedicine, metrology and more… Related Products

Notes:

1. Above data are test results without connectors.

2. Lfiber’s large core fiber coupler (multimode fiber optic splitter) is mode-insensitive and wavelength-insensitive over a broad wavelength range. Also, it can be designed to have an optimum performance for specific wavelength range according to your applications. So please tell us the accurate operating wavelength range if possible.

3. The input and output fibers could be different, for instance, a 1×7 large core fiber coupler (multimode fiber optic splitter) may have one 200/220 μm input fiber and seven 105/125 μm output fibers. In this case, its transmission efficiency is as high as 90% and the splitting uniformity is less than 0.7 dB.

4. Please specify the operating power if the large core fiber coupler (multimode fiber optic splitter) operate on a high-power continuous-wave (CW) laser, it may need a heat sink design for the package.

5. This multimode fiber optic splitter is customizable and above specifications are subject to change without notice.

6. For product customization or special requirement, please contact our sales representative.
