Although the application of agricultural product traceability technology is a key point to realize Modern Agricultural IoT, it has still encountered various food safety problems. For example, immature environmental monitoring technology of agricultural products, weak product traceability and imperfect product monitoring equipment. For this reason, this paper studies and compares several emerging technologies of the things Internet, then it analyzes the functional diversity and practicability of the Modern Agricultural IoT. It builds the experimental environment based on the agricultural product traceability technology, so as to realize the monitoring of crop growth environment and traceability. The result plays a positive role in popularizing the traceability technology of agricultural products and has a certain impact on the development of intelligent agriculture. It has designed and developed a set of crop growth monitoring terminal equipment through experimental debugging. Then it could obtain temperature and humidity, illumination, CO2 concentration, soil data, and other crop growth environment parameters in real time. The relevant data has provided strong support for the traceability model to realize the multi-point monitoring, intelligent control, and automatic operation of crop growing environment. Then it can be sorted and analyzed through the application layer. This system can promote the intelligent processing, improve the utilization efficiency of agricultural resources, promote the development of modern agriculture, save agricultural production costs, and increase the production and marketing. It is an innovative application of the Internet of things technology applied to agricultural production.

With the advent of the era of big data, the Provenance Method of electronic archives based on knowledge graph under the environment of big data has produced a large number of electronic archives due to the development of science and technology. How to guarantee the credential characteristics of electronic archives in the big data environment has attracted wide attention of the academic community. Provenance is an important technical means to guarantee the certification of electronic archives. In this paper, knowledge graph technology is used to provide the concept provenance of electronic archives in large data environment. It not only enriches the provenance method, but also guarantees the certification of electronic archives in the large data environment.

“…Based on [19], to model the WC-MCF-based short reach IM/DD systems, two cores are considered in the analysis: (i) the interfering core is used to generate the XT signal, and (ii) the signal core is used to evaluate signal performance and XT impact. After transmission over MCF, the Jones vector of the optical signal at the output of the signal core, e 0 (t), can be expressed as: e o (t) = A t,x + ms t,x e jωt + A XT ,x +ms XT ,x e j(ω+ ω)t u x + A XT ,y + ms XT ,y e j(ω+ ω)t u y (1) where A t,x is the OC's slowly varying envelope amplitude of the signal core with the phase noise caused by laser linewidth taken into consideration. s t,x is the data signal of the signal core which varies along time and the mean of s t,x is zero.…”

“…Driven by the emerging of 5th-Generation network, cloud services, quantum secured network [1], [2], spatial division multiplexing (SDM) technology has grown rapidly over the past decade, from short-reach to long-haul optical fiber telecommunication systems. Weakly coupled multicore fiber (WC-MCF) based intensity modulation/direct detection (IM/DD) systems are very promising for application in low-cost/high density parallel signal-mode core links, ultrahigh-density trunk/outside plane cables [3], and intra-or inter-datacenter interconnects [4], [5].…”

Weakly coupled multicore fiber (WC-MCF) is promising for use in short-reach fiber telecommunication systems in the near future. Intercore crosstalk (XT) plays an important role in WC-MCF-based short-reach intensity-modulation/direct-detection (IM/DD) systems, because XT can significantly degrade system performance. For the first time, the combined effect of intercore XT and the frequency offset between optical carriers, which is defined as the carrier beating impairment (CBI), is measured and characterized by experiments and numerical simulations. The experimental results show that the CBI causes large fluctuations in the signal-to-noise ratio (SNR) with a normally tolerable XT level. Such SNR fluctuations can additionally reduce the system's XT tolerance (at worst 1-dB SNR degradation) by as much as 20 dB for 4-level pulse amplitude modulation (PAM-4) transmission. The simulation results show that the CBI is mainly affected by the specific properties of the laser source and the modulation depth of the transmitted signals. These results suggest that the XT should be designed to be much smaller for WC-MCF-based short-reach IM/DD systems when there is the CBI. II. WC-MCF-BASED SHORT-REACH IM/DD SYSTEMS A. LASER SHARED SCHEME AND LASER NON-SHARED SCHEME We introduce two types of transmitter schemes for the WC-MCF-based short reach IM/DD systems, namely, the
