一、序言随着光纤制造技术的发展,纤维的单根长度不断增长,然而,分为几段的光纤是经常出现的,为实现可供实用的光纤传输系统,光纤连接技术的确定和提高是实现系统实用化的关键之一。光纤的连接技术主要是,尽可能减小光损耗,接头具有足够的机械强度和可靠性, I. INTRODUCTION With the development of optical fiber manufacturing technology, the single length of the fiber is increasing. However, the optical fiber which is divided into several sections is often appeared. In order to realize a practical optical transmission system, the determination and improvement of the optical fiber connection technology are One of the keys to realize system practicality. Optical fiber connection technology is mainly to minimize light loss, the joint has sufficient mechanical strength and reliability,
