MT ferrule is a multi-core plastic ferrule with compact design, high density and small volume. Its main function is to realize the precise physical docking of optical fibers. MT ferrule is a square ferrule made of PPS plastic injection molding. It has excellent characteristics such as good thermal stability, high mechanical strength, high temperature resistance, corrosion resistance, flame retardant, good dimensional stability, etc. It can realize high density and high precision connection of multiple optical fibers, and each optical fiber has low loss performance. It is widely used in MPO fiber connector manufacturing and optical coupling of devices.
