摘要： An optical add-drop multiplexer (OADM) for adding and dropping wavelength groups for each node among multiplexed and input wavelength groups includes: a wavelength group demultiplexer for separating a plurality of input channels into groups of channels and dropping a channel group required for the node and passing the other groups of channels therethrough; a channel selector for selecting channels from the wavelength group output from the wavelength group demultiplexer and transmitting the selected channels to the area; a channel multiplexer for multiplexing the channels having the same wavelengths as those of the selected channels and input from the area into the wavelength group, and a wavelength group multiplexer for adding the wavelength group input from the channel multiplexer to the wavelength groups that have passed through the wavelength group demultiplexer. Wavelengths required for each node are set to a wavelength group, thereby reducing the time necessary in extending channel capacity or wavelengths in each node. Also, since only a channel selector is additionally installed in an OADM for wavelength extension, wavelength extension is facilitated and a WDM system can be constructed at a low cost. Such an OADM may be used in a wavelength division multiplexing (WDM) optical link.

摘要： PURPOSE: A WDM(Wavelength Division Multiplex) packet transmission system having a ring structure is provided to respectively assign one wavelength to each node connected with a ring structure, and to share the assigned wavelength when remaining nodes transmit packet data to the node, thereby enhancing channel transmission efficiency and reducing the number of optical wavelengths. CONSTITUTION: An optical tap coupler(40) divides received optical signals at a predetermined rate. A signal receiving unit(10) drops a wavelength assigned to a self node in the received optical signals passing the optical tap coupler(40) to receive packet data, and passes the other wavelengths. A receiving read unit(20) reads the existence of packet data by destination nodes transmitted by being loaded on the receiving optical signals divided in the optical tap coupler(40), to decide whether the transmission of the packet data by destination nodes is available and control the transmission of the packet data from a self node to an optional destination node. And a signal transmission unit(30) modulates packet data to be transmitted to an available destination node into an assigned sub-carrier of the destination node, and loads the modulated data on an assigned optical wavelength to be added on the optical signals passing the signal receiving unit(10).

Remotes(21a-21d,22a-22d,23a-23d) connect to each branch connected to the donor(20), and selectively process a plurality of sector signals according to each branch. The donor(20) has a switch matrix for converting a signal input according to each FA(Frequency Assignment) of each sector into an STM-1(Synchronous Transfer Mode-1) signal, and converting the STM-1 signal into an STM-16 signal transmitted to remotes(21a-21d,22a-22d,23a-23d) of each branch when performing a downstream. The switch matrix converts an STM-16 signal inputted according to each branch into a plurality of STM-1 signals, classifies the STM-1 signals into certain sector signals, and outputs a signal added according to the FA of each sector when performing an upstream. The remotes(21a-21d,22a-22d,23a-23d) have a switch matrix for converting an input STM-16 signal into a plurality of STM-1 signals, selecting a signal of a sector necessary for a current remote when performing the downstream. The switch matrix converts an input FA-classified signal into an STM-1 signal, converts the STM-1 signal into an STM-16 signal, and adds the STM-16 signal to a signal inputted from a rear remote.
