Paper Abstract

The optical add/drop multiplexer (OADM) is an important device to realize an auto optical exchange in optical transport network, and tunable filters are one of its central parts. The acousto-optic tunable filter (AOTF) has not only a large wavelength tuning range (more than 100nm), low optical loss (less than 5dB) and a narrow filter bandwidth (about 1nm), but also dynamic and reconfigurable characteristics. Thus, the acousto-optic tunable filter (AOTF) is one of powerfully several potential candidates. In the paper, the main works are to test and analyze the sidelobes characteristics of TeO2 AOTF with different bandwidth and its influence on the crosstalk between the neighbor channels. The new structure of OADM based on the AOTF is suggested to lower the influence of signal crosstalk.
