Abstract

An embodiment of the present application provides an optical network device and an optical module. The optical network device includes: a processing chip, a first optical transmission component, and a second optical transmission component; the processing chip is used to: receive N electrical signals sent by a single-board interface chip, N is an integer greater than 2, converting the received N electrical signals into two electrical signals, which are respectively represented as a first electrical signal and a second electrical signal; and sending the first electrical signal and the second electrical signal to the first electrical signal respectively An optical transmission component and a second optical transmission component; the first optical transmission component is used to convert the first electrical signal into a first optical signal; the second optical transmission component is used to convert the second electrical signal into a second optical signal. Since the N electrical signals to be sent obtained by the processing chip are merged, there are only two optical transmission components connected to the processing chip, so there is no need to connect four optical transmission components to the processing chip, which reduces the number of optical transmission components. Reduced costs.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to an optical network device and an optical module. Background technique [0002] With the advent of the 5G era, the demand for network bandwidth is getting higher and higher, and high-speed interfaces such as 100GE interfaces, 200GE interfaces, and 400GE interfaces are more and more widely used. Taking the 100GE interface as an example, in order to realize the communication of the 100GE interface, in the sending direction, the optical network equipment uses 4 optical transmitters (Optical Transmitter), and the non-return to zero code (Non-Retum to Zero, NRZ) code is used to realize The 4*25.78125G electrical signal is converted into an optical signal, and then multiplexed through oMUX, that is, the four 4*25.78125G optical signals are transmitted through the same optical fiber. In the receiving direction, the optical network equipment rece...
