    摘要: A crosshead die for a plastic optical fiber fabrication system is provided. The crosshead die includes a body, an insert, mounting flanges on the upstream and downstream end for securing the crosshead die to adjacent equipment or another crosshead dies, an axial port for receiving a mixed molten material that makes up the core, and a radial port for receiving a mixed molten material that makes up the outer layering material to be co-extruded over the core. The die insert includes a material distribution channel system that provides substantially the same linear distance for the mixed molten material to travel prior to the co-extrusion. If multiple die inserts are utilized, the crosshead die is able to co-extrude multiple layers over the core. If the crosshead dies are serially assembled, additional concentric layers of material can be co-extruded atop the layered plastic optical fiber extruded from the upstream crosshead die.
