【摘要】 分析了一种新的OADM节点结构———广播与选择型光分插复用器。比较了广播与选择型与传统的全连通三维光交换和波长分层OADM的性能。说明了广播与选择型OADM能显著地减少直通信道中的插入损耗,具有内在光谱均衡能力。讨论了OADM在超长距离传输网络和保护环中的应用。更多还原

【Abstract】 A new node architecture of OADM——The B&S OADM is Analyzed. The optical performance of B&S OADM and the conventional fully-connected three-dimension switching and wavelength-layered OADM is compared. The B&S OADM enables lower through loss and has the DSE function. The OADM application in the ultra-long haul network and protection rings is discussed.更多还原
