ADSS光缆选型的误区

目前,无论是用户还是生产厂家,在ADSS光缆选型时,除了提出光缆的光纤芯数之外,往往以“跨距”来定义ADSS光缆。文章指出ADSS光缆仅用“跨距”来表达,尽管很直观却是非常不严格的,这是一个误区。脱离气象条件、弧垂和应力的“跨距”不仅不准确、不完整,且导致误入歧途,因为ADSS光缆的“跨距”不但与光缆本身的机械强度有关,还与弧垂、气象条件相关。并且是可变化的。

Misleading for selection of ADSS type

When the customer as well as the manufacturers selects the ADSS types, besides considering the fiber numbers of ADSS, sometimes they define ADSS type based on span. This paper pointed out that this is a misleading, though it is quite straight. It is not very strict if ADSS is defined only based on span. Without considering meteorology, the curve droop and the strain of ADSS, the "span" will be incorrect and incomplete and it will even cause misleading, because the "span" of ADSS is not only related to the mechanical strength of the cable itself, but also related to its curve droop, meteorology, and the "span" is also changeable.
