我不着急要的,一个星期都可以.995把.可以的说下
Passive optical networks are the most important
class of fiber access systems in the world
today.This article first reviews the reasons why
the PON as a general architecture is so important.
We then outline in some depth the technologies
used to implement this architecture,
including the G-PON and E-PON systems being
deployed today,and the advanced PON systems
that provide the evolution path to ever higher
bandwidths.
