THE SYSTEM OF OPEN OPTICAL ACCESS NETWORK

摘要

PURPOSE: An open type optical subscriber network system is provided to enable a user to change services by connecting a plurality of service and user through an optical infra without wavelength selectivity. CONSTITUTION: An optical line terminal part transmits and receives the optical signal of the specific transmission channel among the entire transfer channel which the light infra accepts. The optical network end part transmits a modulated optical signal of the predetermined transmission channel in the optical line terminal part to the optical line terminal part. An optical line terminal part and the optical distribution/joint part are included in the optical line terminal part.
