Optical Characteristics and Reliability of Plastic Ferrules for MU-Type Simplified Receptacles(Connector and Sliding Contacts)(<Special Section>IS-EMD2003 : Recent Technical Trend of Electro-Mechanical Devices)

概要

論文の詳細を見る
Plastic ferrules for single-mode (SM) MU-type simplified receptacles are fabricated with a precise injection-molding technique using a liquid crystalline polymer (LCP). The fabricated plastic ferrules exhibit an eccentricity of <0.6μm and outer diameter variation of ±1μm. MU-type simplified plugs incorporating the plastic ferrules have an average insertion loss of 0.13 dB and a return loss of >46dB. The plastic ferrules exhibit good resistance in 500-cycle mating tests, and in vibration and impact tests as well. The initial optical characteristics are maintained during a temperature and humidity cycling test and a heat-cycling test.
