Abstract Optical add-drop multiplexer(OADM) based on fiber Bragg grating is discussed . Two kinds of novel four wave wavelength OADM structures are analyzed. One kind of OADM is based on bidirectional type. The other kind of OADM is based on beam splitter and bidirectional type. Bidirectional OADM can transmit optical signal from two directions, this can make the system structure in the relatively small use of circulator, it can reduce system loss. The output spectrum was more close to the original spectrum. OADM based on beam splitter and bidirectional type increases transmission channel number. The OptiSystem software is used to simulate two kinds of structures, the simulation experimental results show that both kinds of OADM can implement four wavelength channels′ uploading and downloading simultaneously.
