Effect of Surface Roughness Profiles on Optical Characteristics of Plastic Split Sleeves for Single-Mode Fiber-Optic Connectors

摘要

We successfully fabricated split alignment sleeves for single-mode operation with the injection-molding tech- nique using both thermosetting epoxy resin and thermoplastic polyetherimide (PEI) resin. The relationship between the sur- face smoothness and the connection-loss characteristics of these injection-molded plastic sleeves was investigated. We made two- dimensional contour maps of the outer and inner surfaces of the plastic sleeves using the measured surface roughness.
