The invention discloses a structure with intelligent
wavelength routing optical network nodes which supports the
link management protocol, the transmit-couple- exchange structures are added to the present simple optical exchanger, the input part of the transmit-couple- exchange structure is made up of several 1x2 branching unit, the optical door switches with the same quantity, one star-coupler and
receiver; the output part is made up of one
transmitter, several 1x2 optical switches, one optical door switch and several 2x1 coupler. The
message format controlled and transmitted by control plane
software modules with universal multi-mark exchange is in line with the data
package format and
processing mechanism defined by the
link management protocol (LMP), the transmit-couple-exchange structure ensures that the data from control plane
software modules can select any output
optical fiber through the node and be transmitted to the others nodes. The invention can support adjacent nodes automatically verify and detect the relation of
optical fiber connection between two adjacent nodes, the corresponding relation of all ports on one node can be automatically detected by the follow-up
route signal command and transmitting and
coupling structure.
