Description

Technical Field

[0001] The present invention relates to the fields of optical fiber communication and optical fiber sensing, and more specifically, to a same-wavelength channel interaceptive fusion method and system for optical interconnection of intelligent computing centers. Background Art

[0002] In recent years, with the development of new applications such as the Internet of Things and cloud computing, network traffic has grown exponentially. Recently, a number of AI big models such as ChatGPT, which have become the focus of the network, have announced the advent of the era of intelligent computing. AI big models have reshaped the face of various industries and brought great convenience to many jobs. The convenient intelligence relies on the support of huge computing volume. These new applications, especially the emergence of big models, have brought about the demand for bandwidth and computing resources, further promoting the development of short-distance (<80 kilometers) optical fiber communication systems in intelligent computing centers. From the upgrade of GPT4 with trillion parameters to GPT5 with ten trillion parameters, the data and parameters have increased by only 10 times, but the computing power required has increased by 20 to 100 times. With the update and iteration of big models, the increasing computing power required has forced the data center to accelerate the transition to 800G, and the 1.6T solution has also begun to sprout. Stimulated by the growing demand for capacity, the scale of optical interconnection in the intelligent computing center has also expanded, which is bound to bring about the operation and maintenance problems of massive optical fiber infrastructure. By giving the optical fiber network sensing capabilities, the optical fiber communication system and the optical fiber sensing system are organically integrated on the same optical fiber, which helps to build a win-win situation in which perception helps communication and communication empowers perception. Data centers use a high-spectral-efficiency integrated communication and perception system. At the cost of sacrificing a small amount of communication capacity, they can use perception to enhance communication, provide large-scale automated operation and maintenance capabilities for data centers with increasingly large network scales, and meet the operation and maintenance needs of massive optical fiber infrastructure. Fiber optic sensing technology transmits periodically repeated detection signals, relies on the continuous backscattering of optical signals on the optical fiber, brings back the status information of the optical fiber, and realizes the detection of the surrounding environment of the optical fiber. However, the sensing detection signal is a "noise" that needs to be avoided for the forward transmission communication system. Early communication and perception integration solutions separated the communication system and the sensing system in different wavelength channels through space division multiplexing, mode division multiplexing, and wavelength division multiplexing to avoid potential mutual influence between the inter-sensory systems.

[0003] A communication and sensing integrated system based on multi-core optical fiber uses different channels of the multi-core optical fiber as transmission links to construct optical signal transmission links and optical fiber sensing links respectively. For a multi-core optical fiber, two of the cores are selected as sensing links, and the remaining cores are used as information transmission links. For each link, at the transmitting end, the invention uses a laser to construct an N-channel optical frequency comb, and the optical frequency comb is composed of N wavelengths. In the multi-core optical fiber, two sensing cores are used as sensing fibers, and the rest are signal transmission fibers. At the output end, of the two sensing cores, the odd wavelengths of the first sensing core are output at the output end, and the even wavelengths of the second sensing core are output at the output end. After passing through the optical fiber signal amplifier, they are coherently received with the transmission signal in the signal transmission link. However, this method requires occupying multiple channels, and a large amount of spectrum resources are not utilized, and the spectrum efficiency is low. Summary of the invention

[0004] The purpose of the present invention is to disclose a same-wavelength channel interaceptive fusion method and system for optical interconnection of intelligent computing centers with more harmonious coexistence of communication and sensing

[0005] In order to achieve the above object, the present invention provides a same-wavelength channel interawareness fusion method and system for optical interconnection of intelligent computing centers, including:

[0006] S1: frequency modulate the continuous signal to generate a frequency modulated continuous wave signal; generate a communication signal; multiplex the frequency modulated continuous wave signal and the communication signal on the same wavelength channel and transmit them to the optical fiber link through the integrated transmitter;

[0007] S2: The forward receiving end receives the forward transmitted frequency modulated continuous wave signal and the communication signal through the optical fiber link to obtain the receiving end frequency modulated continuous wave signal and the receiving end communication signal; the backward receiving end receives the backscattered signal of the frequency modulated continuous wave signal through the optical fiber link to obtain the backscattered signal;

[0008] S3: Use the frequency modulated continuous wave signal at the receiving end to perform noise compensation on the communication signal at the receiving end to obtain a compensated communication signal; realize communication according to the compensated communication signal; and realize perception using the backscattered signal.

[0009] Further, in step S1, the communication signal is a digital subcarrier multiplexed signal; frequency modulating the continuous signal to generate a frequency modulated continuous wave signal includes:

[0010] A DC signal with amplitude A is repeated for a period of t. r The frequency modulation is performed to obtain a periodically swept frequency signal as a frequency modulated continuous wave signal, where a single cycle is expressed as:

[0011]

[0012] where φ FM(t) is the phase term produced by frequency modulation.

[0013] Furthermore, in step S1, when the frequency modulated continuous wave signal and the communication signal are multiplexed on the same wavelength channel, it includes: through a digital subcarrier scheme, the number, bandwidth and position of subcarriers are flexibly adjusted in the digital domain, an appropriate spectrum position is reserved for the frequency modulated continuous wave signal, and the communication signal and the frequency modulated continuous wave signal are synesthetically fused.

[0014] Furthermore, in step S1, transmitting to the optical fiber link through the synaesthesia integrated transmitting end includes: before transmitting through the circulator of the synaesthesia integrated transmitting end, amplifying the optical power by using an erbium-doped fiber amplifier, and filtering out amplified spontaneous radiation noise by using a filter.

[0015] Further, in step S2, the forward receiving end receives the forward transmitted frequency modulated continuous wave signal and the communication signal through the optical fiber link, and obtains the receiving end frequency modulated continuous wave signal and the receiving end communication signal, including: before the forward receiving end, the receiving optical power is controlled by variable optical attenuation, and then the forward synaesthesia fusion signal is received by a coherent receiver, and converted into a digital signal for storage through a data storage oscilloscope, so as to obtain the receiving end frequency modulated continuous wave signal and the receiving end communication signal.

[0016] Further, in step S2, the backscattering signal of the frequency modulated continuous wave signal is received by the back-receiving end through the optical fiber link, and the backscattering signal is obtained, which includes: at the backscattering receiving end, the backscattering signal transmitted back on the optical fiber link is output through a circulator, and before receiving, the optical power is enhanced by an erbium-doped fiber amplifier and the spontaneous radiation noise is amplified by a filter, wherein the external disturbance of the optical fiber to be tested is simulated by a piezoelectric ceramic telescopic tube, and finally the backscattering signal light and the local oscillator light beat frequency are coherently received, and digital storage is completed through a data acquisition card to obtain the backscattering signal.

The strain change caused by external disturbance is proportional to the phase change of the scattered light. The position, size and frequency of the strain applied by the piezoelectric transducer on the optical fiber can be monitored through the phase change to realize external environment perception.

[0020] Furthermore, the duration of the FMCW sensing detection signal is the entire repetition period, that is, the effective signal duty cycle is 100%, which can make full use of time resources and reduce its peak-to-average power ratio, solving the problem of mutual aliasing of scattered light in adjacent periods of the FMCW. It is only necessary to satisfy the following relationship when dividing the sub-pulses by matching filtering at the receiving end:

[0021] Where N is the number of sub-pulses, B is the bandwidth of the continuous wave signal, T is the loop delay, t r is the repetition period of the detection signal and c is the speed of light.

After obtaining the starting point of the frequency sweep, the phase term φ applied by the frequency modulation at the transmitting end is restored. FM (t), and recover the periodic frequency offset modulated onto the FMCW signal, expressed as:

[0024] p ′ (t)·exp{jφ FM (t)}

[0025] =A ′ ·exp{-jφ FM (t)+jφ PN (t)}·exp{jφ FM (t)}

[0026] =A ′ ·exp{jφ PN (t)}

[0027] where φ PN (t) is the phase noise of the communication system.

[0028] In addition, the present invention also provides a same-wavelength channel interawareness fusion system for optical interconnection of intelligent computing centers, including:

[0029] Transmitter module: frequency modulates the continuous signal to generate a frequency modulated continuous wave signal; generates a communication signal; multiplexes the frequency modulated continuous wave signal and the communication signal on the same wavelength channel and transmits them to the optical fiber link through the integrated transmitter;
