The embodiment of the present application discloses a network device and a terminal device. The method in the embodiment of the present application includes: the network device includes: a digital optical signal generation unit, an analog optical signal generation unit, and a signal processing unit; the digital optical signal generation unit is connected to the first end of the signal processing unit, and the analog optical signal generation unit is connected to the first end of the signal processing unit. The second end of the signal processing unit is connected, and the third end of the signal processing unit is connected to the optical splitter in the network; when the digital optical signal generating unit inputs the digital optical signal to the signal processing unit, and the analog optical signal generating unit sends the When the signal processing unit inputs the analog optical signal, the signal processing unit processes the digital optical signal and the analog optical signal, so that the digital optical signal and the analog optical signal can be transmitted on the same optical fiber, and then sent to the terminal equipment through the optical splitter The digital optical signal and the analog optical signal, the wavelength of the digital optical signal and the wavelength of the analog optical signal are different.
Description
technical field [0001] The present application relates to communication technologies, and in particular to a network device and a terminal device. Background technique [0002] With the development of mobile communication technology, the demand and quality requirements of communication services are getting higher and higher. At present, the long term evolution (LTE) system uses a high frequency band and a large bandwidth, which can meet the growing business needs and high-speed bandwidth requirements; however, due to the high frequency band used by the LTE system, the loss is large, As a result, the indoor coverage capability of the LTE network is poor, and the coverage quality is poor. [0003] At present, through the building sparring scheme, the antenna signal passes through the building to achieve better indoor area coverage indoors, that is, the coverage capacity is increased through inter-building sparring. [0004] However, in the scheme of building sparring, the an...
