Multimode fiber end-face reflection
The end face of APC connectors is polished to an 8° angle, which effectively discharges reflected light from the fiber core, significantly reducing return loss, which can usually reach below -60 dB. MPO (Multi-Fiber Push-On) connectors are high-density fiber optic connectors designed to carry multiple fibers—typically 12 or more—within a single interface. SN®-MT They support both single-mode (SM) and multimode (MM) fibers and are widely used in space-constrained environments requiring high. Multimode APC connectors, especially, combine the advantages of multimode fiber with the high performance of APC polishing technology, providing a reliable solution for applications that require high bandwidth and high stability signal transmission. They include the Physical Contact (PC), Ultra Physical Contact (UPC) and Angled Physical Contact (APC).
