Notes:
1. The optical performances of the multimode fiber couplers (without connectors) are measured with an overfilled-launch light source.
2. Different light sources and launching conditions may bring about changes in the test results.
3. Different split ratios are available on request.
4. 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.
5. 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.
6. 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.
7. If a high-quality output beam (with fewer speckle hot spots and more uniform energy intensity profile) is needed, the large core fiber coupler can be integrated with LFIBER’s In-line Laser Speckle Reducer (Fiber Optical Beam Homogenizer) to make a hybrid component. For more info, click In-line Speckle Reducer / Laser Beam Homogenizer.
8. This multimode fiber optic splitter is customizable and above specifications are subject to change without notice.
9. For product customization or special requirement, please contact our sales representative.
