请问光接口板的长距中距短距有什么区别？

代码的第一位字母表示应用场合：
I表示局内通信；S表示短距离局间通信；L表示长距离局间通信。

字母横杠后的第一位表示STM的速率等级：
1表示STM-1；4表示STM-4；16表示STM-16；64表示STM-64。

第二个数字（小数点后的第一个数字）表示工作的波长窗口和所有光纤类型：
1和空白表示工作窗口为1310nm，所用光纤为G.652光纤；
2表示工作窗口为1550 nm，所用光纤为G.652或G.654光纤；
3表示工作窗口为1550nm，所用光纤为G.653光纤。

应用场合 局内 短距离局间 长距离局间
工作波长(nm) 1310 1310 1550 1310 1550
光纤类型 G.652 G.652 G.652 G.652 G.652 G.653
传输距离(km) ≤2 ～15 ～40 ～60
STM-1 I—1 S—1.1 S—1.2 L—1.1 L—1.2 L—1.3
STM-4 I—4 S—4.1 S—4.2 L—4.1 L—4.2 L—4.3
STM-16 I—16 S—16.1 S—16.2 L—16.1 L—16.2 L—16.3

这些都表示传输距离，s是短距，l是长距！

那到底是几公里呢？
STM-1的S-1.1和STM-4的S-1.1传输距离也不一样吗？

回复 3# 的帖子
对于相同类型的光接口，速率越高传输距离越短

STM-1的S-1.1和STM-4的S-4.1的传输距离是不一样的，但相差不多，但和S64.1相差就很多了！

具体可以传多远，根据光缆质量有关，每公里衰减与传输距离有很大关系！！！
