It is noted that in the following description, reference is made to the accompanying drawings which illustrate several embodiments of the present application. It is to be understood that other embodiments may be utilized and that mechanical, structural, electrical, and operational changes may be made without departing from the spirit and scope of the present application. The following detailed description is not to be taken in a limiting sense, and the scope of embodiments of the present application is defined only by the claims of the issued patent.

As shown in fig. 1, a schematic structural diagram of a conventional service transmission system is shown. In the transmission process from the office end to the far end, the service equipment using the color light module multiplexes multiple services on the same optical fiber through the wave-combining wave-splitter at the office end, utilizes the optical layer equipment and transmits the multiplexed services to the far end through the optical cable, and the optical layer equipment at the far end receives signals, separates different optical signals through another wave-combining wave-splitter and transmits the signals to the service equipment at the far end.
Taking an 8-wave 8 port in fig. 2 as an example to illustrate a transmission scheme in the prior art, a color optical module is used on a service device, λ 1- λ 8-total 8-wave service is used, 16-pair optical cable connection needs to be used between the service device and a wavelength combiner/demultiplexer, and wavelengths of λ 1- λ 8 need to be correspondingly connected on the wavelength combiner/demultiplexer. It should be noted that, after the optical module is inserted into the service device, only the Tx port and the Rx port are provided to the outside, and the wavelength cannot be physically distinguished. The rear end of the output fiber of the wave combiner/demultiplexer is connected with the optical layer optical amplifier, and the optical layer optical amplifier is connected with the line optical cable. Based on a similar principle, the opposite end also needs to be correspondingly connected with wavelengths from λ 1 to λ 8, and the two port modules need to be paired to transmit services.
Although this solution can solve the service transmission requirement and save the fiber resource by the wavelength division technology, the following problems still exist: 1) since the color light module is used at the equipment side, the operation and maintenance need to reserve a plurality of wavelength modules of different types, which can increase the operation cost; 2) the wavelength table is needed to be compared with the combination/de-multiplexer to correspond to the switching-on and maintenance, so that the operation and maintenance difficulty is increased; 3) the service equipment and the wave-combining wave-splitting device need a plurality of optical fibers for connection, the wave-combining wave-splitting device and the optical layer equipment also have physical optical fiber connection, external connecting fibers need corresponding ports, operation and maintenance difficulty is high, and meanwhile, due to the external connection of the optical fibers, service interruption caused by artificial mistaken collision can occur; 4) the separated equipment, equipment management and network management need to invest more cost, space needs to be reserved between the equipment, the machine frame space is occupied by the separated equipment, and machine room space resources are wasted.
In view of this, the invention provides an integrated wavelength division system and an integrated wavelength division device, which can effectively solve the problems of operation, maintenance and management, save cost, improve management efficiency, facilitate quick networking, and have obvious advantages of quick opening, reduction of operation and maintenance difficulty and the like. In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention are further described in detail by the following embodiments in conjunction with the accompanying drawings.
