Study of a Novel Bi-Directional Optical ADD/DROP Multiplexer
新型双向光分插复用器结构实验

A novel BOADM structure based on fiber gratings and circulators and two experimental structures are proposed. The experimental result shows that the heterohyne crosstalk and homodyne crosstalk of BOADM are -21.4 dB and -32 dB at the channel space of 100 GHz. Moreover, the BOADM , which used unidirectional EDFA is simple,cost-effective and easy fit to other equipments, besides, it has self-healing ability.
