胶层非连续气泡对电连接器灌胶性能的影响分析

电连接器灌胶固化后,目测发现个别胶层存在若干非连续性的直径不大于2mm的气泡,经过大量试验,胶层中出现气泡的现象始终无法消除。为此,本文对电连接器灌胶后胶层存在非连续气泡的现象进行研究,采用力学仿真和绝缘性能测试的方法分析和测试了胶层非连续气泡对电连接器灌胶性能的影响。结果表明,胶层非连续气泡对电连接器灌胶性能的影响可以忽略不计,因此胶层含有非连续气泡,且直径不大于2mm时,该电连接器仍然为合格品。

Influences of polishing on return loss of optical fiber connectors

With Al2O3 and SiO2 as polishing medium, under different polishing conditions, e.g. with different polishing pressure, polishing time and polishing fluid, the influences of polishing treatment on the return loss of optical fiber connectors were investigated. The return loss of optical fiber connectors is 32CD*238dB before polishing. The results show that dry polishing（i.e. no polishing fluid） with Al2O3 has less influence on return loss of optical fiber connectors, while dry polishing with SiO2 reduces return loss to about 20dB because of the end-face of optical fiber contaminated. The wet polishing（i.e. using distilled water as polishing fluid） with Al2O3 or SiO2 can increase return loss to 45CD*250dB, but wet polishing with Al2O3 may produce optical fiber undercut depth of 80CD*2140nm. Wet polishing with SiO2 should be preferentially selected for optical fiber connectors and polishing time should be controlled within 20CD*230s.
