Abstract: A crosshead die (16) for a plastic optical fiber fabrication system (10) is provided. The crosshead die (16) includes a body (28), an insert (32), mounting flanges (58) on the upstream (25) and downstream end (26) for securing the crosshead die (16) to adjacent equipment or another crosshead dies (16), an axial bore (14) for receiving a mixed molten material that makes up the core, and a radial bore (36) for receiving a mixed molten material that makes up the outer layering material to be co-extruded over the core. The die insert (32) includes a material distribution channel system (70) 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.

Abstract: A retainer clip (10) for holding a gasket (14) between the ends of two coupling components (16, 18) includes a first resilient annular member (42) extending circumferentially about two-thirds of a circle, a second resilient annular member (44) having circumferential ends and a discontinuity between the ends, and a bridge connecting the first (42) and second (44) resilient annular members. The bridge has a circumferential extent of less than 45 DEG , and the first resilient annular member (42) is circumferentially expandable without causing the second resilient annular member (44) to expand.
