摘要
介绍了多功能双向光纤传输平台(HFC)的系统方案、硬件实现和实验结果,整个系统包括上行光端机、下行光端机、频率变换器、频谱监测器、射频调制解调器以及网络管理软件。其技术特点包括具有远程监控功能的智能化光端机,采用频率变换和复用技术扩展上行频带、上行频谱在线监测和多功能中文网管。
This paper proposes the scheme, hardware implementation and experiment result of HFC. The system is composed of upward and downward channel optic transmission equipments, shifting frequency equipment, monitoring spectrum equipment, modulator/demodulator and network management software. The novel characteristics include intelligent fiber optic transmission equipment with remote monitoring and controlling, upward spreading channel spectrum using frequency shifting and multiplexing, online monitoring of the upward channel spectrum,and Chinese network management system.
