Abrégé
(EN)
The embodiments of the present invention relate to a wireless fronthaul passive optical network (PON) system, an optical network device and a method. An OLT performs wireless compatibility processing on data received from a CPRI interface of a BBU and then divides the data into a data part and a control word part, which two parts can be processed respectively, such that the data part can be compressed as far as possible to reduce the fronthaul bandwidth, thereby increasing the transmission efficiency.

(ZH)
本发明实施例涉及一种无线前传无源光网络PON系统、光网络设备及方法,通过OLT对从BBU的CPRI接口接收到的数据进行无线兼容处理后分成数据部分和控制字部分,可以对这两部分进行分别处理,从而可以尽可能的压缩数据部分而降低前传带宽,提高了传输效率。
