摘要：Optical communication network includes that multiple passive optical network(PONs) are connected to ring and enter to locate PON sequence of addresses, whereinthe communication channel between each terminal is wavelength-division multiplex. Eachoptical link between adjacent PONs includes tunable wavelength filter, selection isdynamically arranged for the wavelength of connection with a common wavelengthallocation database and provides corresponding control signal to filter appropriate, tomake the wavelength for a connection of distribution only can be by the transmissionchannel between each terminal. Therefore, identical wavelength can be reused, whosetransmission path another, which connects, does not require overlapping to be related tothose wavelength with any existing transmission path.
