在光纤接续领域,机械式光纤接续和熔接接续是实现光纤固定连接的两种不同方式。机械式光纤接续,是指不需要熔接机,只通过简单的接续工具、利用机械连接技术实现单芯或多芯光纤永久连接的方式。本文将重点介绍机械式光纤接续技术在光纤到户(FTTH)中的应用优势。
In the field of optical fiber connection, the mechanical fiber connection and thermo-weld are two different ways of realizing the fixed connection of optical fiber. The mechanical optical fiber refer connection to the way of eternal connection for single or multiple chip fibers that does not need welder, but through simple connecting tools and mechanical connection techniques. This paper will mainly introduce the advantages of mechanical optical fiber connection techniques in FTTH.
机械式光纤接续所采用的机械式光纤接续子,不同厂家由于设计结构和所采用的核心技术不同,性能和操作方式有很大的区别。在选择机械式光纤接续子时,所要评估的方面应主要包括:工具的投资及其维护需求、工具的简单及轻便性、安装的便利性、光纤对准器件的可靠性和夹持力(直接影响接续衰减的大小)、对环境的适应性、是否有耗材、及长期使用稳定性等等方面。
The mechanical optical fiber connector adopted by the mechanical optical fiber connection differs dramatically in performances and operation ways among manufacturers as they take different core techniques for structure design. The assessing criteria for choosing mechanical optical fiber connectors shall include: requirements on tool, investment, and maintenance; simpleness of tool, convenience for installation, reliability and holding force (which directly decides the continuous attenuation) of optical adjusting device, adaptability to environment, whether using consumptive material, and stability for long term use, etc.
机械式光纤接续技术本身并不是一个新兴的技术,早在20年以前就已经有产品诞生,在美国和日本的数据和图像传输中有较多应用。光纤机械接续技术在国内1990年以后一直被应用在线路抢修、特殊场合的小规模应用等等工程实践当中。近年来随着光纤到户( FTTH)在全球范围内特别是日本大规模部署,使人们更加认识到机械式光纤接续作为一种重要的光纤接续手段在光纤到户( FTTH)最后100米部署中的意义。
The mechanical optical fiber connecting technique itself is not a novel technique. This kind of product is emerged 20 years age and is widely used in data and image transmission in the States and Japan. After 1990, the optical mechanical connection technique in our country has been used in engineering practices like circuit rush repair, and small scale application in some special occasions. Recently, with the worldwide spread of FTTH, especially in Japan, people started to realize the significant importance of mechanical optical connection as an optical fiber connection method in the last 100m deployment of FTTH.
