Optical Performance Evaluation of MT Connector Employing Solid Refractive Index Matching Material for High-Power Optical Transmission

We evaluate the high-power durability of multi-fiber optical connectors that use solid refractive index matching material designed to increase the number of fibers in multi-fiber connectors. We measured the temperature and return loss while passing high-power lights through optical fiber connections with gaps of several tens of microns filled with the refractive index matching material. We confirmed that the multi-fiber connector using the solid refractive index matching material did not deteriorate even at powers of 200 mW.
