摘要
无源WDM技术是现阶段5G前传采用的主要技术。由于5G前传的速度高达25 Gbit/s,色散成为影响5G前传的主要因素。本文介绍了无源WDM前传方案的技术原理和常用模型的波长分配,通过对光模块的发送和色散代价(TDP)指标的研究,分析了TDP的各影响因素及其对5G前传的影响,最后结合光纤链路传输指标要求,提出了无源WDM技术在5G前传中的部署建议。
Passive WDM technology is the main technology used in 5G forward transmission at this stage.As the speed of 5G forward transmission is as high as 25 Gbit/s,dispersion becomes the main factor affecting.This paper introduces the technical principle of passive WDM in forward transmission and its wavelength assignment in common models.It studies the TDP index of optical module and analyzes its infl uence in 5G forward transmission.Finally,it analyses the transmission index of optical fi ber link and proposes the suggestions of passive WDM technology in 5G forward transmission.
