介绍一下E1、FE、GE、POS传送距离（包括光纤传输方式），如果超过这个距离如何办？都改为光纤传输么？以及这些传输方式如何转换？是用协议转换器么？

(Introduce the transmission distance of E1, FE, GE, and POS (including optical fiber transmission method). What if the distance exceeds this distance? Are they changed to fiber optic transmission? And how are these transports converted? Are you using a protocol converter?)
