Embodiment Construction

[0046] see figure 1 As shown in FIG. 1 , it is an architectural diagram of the metropolitan area network based on the embodiment of the present application. The metropolitan area network mainly includes three layers, which are the access layer, aggregation layer and core layer. The core layer mainly provides high-bandwidth service bearing and transmission, and completes the interconnection with the existing network. The existing network can include asynchronous transfer mode (English: asynchronous transfer mode, referred to as: ATM) network, digital data network (English: digital data network, referred to as: DDN), Internet Protocol (English: internet protocol, referred to as: IP) network, etc. The main function of the aggregation layer is to provide service access nodes with the aggregation and distribution of user service data, and at the same time realize the service level classification of services. The access layer utilizes multiple access technologies to allocate bandw...

Abstract

The application discloses an optical module and a network device, which are used to solve the problem of high bandwidth occupancy rate of the existing optical module. The optical module is located in the first network device of the access ring, and the access ring also includes a second network device and a third network device, and both the second network device and the third network device are optically connected to the first network device, and the first The network device is applied to the access point, and the optical module includes: a first multiplexer / demultiplexer and an optical receiver; wherein, the first multiplexer / demultiplexer is used to receive the first optical signal from the second network device and the first optical signal from the first optical Separate the second optical signal with the first wavelength from the signal, and transmit the second optical signal to the optical receiver; the first multiplexer / demultiplexer is also used to transmit the third optical signal to the third network device, wherein, The third optical signal is an optical signal of a wavelength other than the first wavelength separated from the first optical signal; the optical receiver is used for receiving the second optical signal.

Description

technical field [0001] The present application relates to the technical field of optical communication, and in particular to an optical module and network equipment. Background technique [0002] With the development of communication technology, in the 5th generation (English: the 5th generation, 5G for short) communication technology, the bandwidth requirements of the bearer network are getting higher and higher. [0003] In the current metropolitan area bearer network, the network is formed based on the packet transport network (English: packet transport network, PTN for short), and the access layer adopts the access ring. The access ring includes multiple PTN devices. Multiple PTN devices include PTN devices as access points and PTN devices as convergence points. Each PTN device includes an optical module. The bandwidth supported by the optical module included in each PTN device on the existing general access ring is also It represents the bandwidth supported by the PTN ...
