New Description: [New Technology Field] [0001] This creation is about configuring a full-color multi-channel optical signal plug-in multiplexer, especially the split-wavelength and wavelength-cycle characteristics of the arrayed waveguide grating. The filter modulation of multiple Bragg fiber gratings achieves the plugging of optical signals, thereby providing a more advanced field of optical communication network technology. [Prior Art] [0002] With the Next Generation Network (NGN), the all-IP network integrates the traditional switched network (PSTN), wireless network (Wireless Network) and the Internet. The network (Interne_t) on a single network, to enhance the application services such as data, data, voice, multimedia and information security, the demand for bandwidth is growing. In order to realize the next generation of all-in-one networks, optical communication is one of the methods that most people consider to increase the bandwidth requirement, and it has the possibility of transmitting 50 megabits per second. An optical add/drop multiplexer (0ADM) has an optical input component with input input, output output, drop 及drop, and uplink 璋add, and a high-density multiplexer system (Dense wavelength- Division multiplex-ing (DWDM) is mainly used to perform regional uplink, add, and drop optical wavelength signals to be processed by the optical network. The transmitted signal will not exist after that, and the optical wavelength signal that has been taken offline will be transferred to the network in the future. At this time, the local user

Through the optical signal plug-in multiplexer, the modulated signal can be added from the uplink and sent out through the output to carry local information into the optical network. Therefore, the optical signal plug-in multiplexer has the characteristics of repeated wavelength reuse. 'So you can reduce the number of wavelengths used, which in turn can increase the amount of data transferred. In general, a conventional optical signal plug-in multiplexer with one channel is composed of a 解 multiplexer, a 2x2 optical switcher, and an Nxl multiplexer, as shown in the fifth figure. . When N wavelength channel optical signals are transmitted to the input port, the first step of the architecture is to perform the demultiplexing multiplexing operation through the demultiplexing multiplexer, and each optical wavelength signal will enter a 2x2 optical sounding device.

The wavelength signal enters the multiplexer to match the wavelengths. However, if the optical wavelength signal is not removed via the 2x2 optical switch, the wavelength is transmitted directly to the multiplexer. The multiplexer aggregates all the signals to be transmitted and transmits them to all wavelength signals to their destination nodes. In the traditional optical signal plug-in multiplexer (see Figure 5), one optical wavelength signal is split and coupled through a set of demultiplexers and multiplexers, so the filter waveform of the multiplexer must be The requirement is very precisely matched to the demultiplexer, which also reflects that when the number of wavelengths increases, the yield is necessarily reduced. In order to improve the waveform matching problem, the multiplexer and multiplexer are integrated into one ΝχΝ.
