呼啸山人,但是我从一份英文原版资料中看到如下:共有三个图,原文如下
shows symbols for three of branching components,where (b) and (c) are special case of (a).
其中(a)star coupler,(B)tree coupler,splitter or combiner,(C)wdm
所以我认为分支器应该是耦合器的一种特例,你认为呢?
请看bellcore的定义
coupler:Synonym for branching component,when used to combine single from several fibers ontoone fiber.Opposite of splitter.
Splitter:A branching component that serves to divide optical power.
这可是bellcore的定义哦,我晕
