Abstract:This paper proposes a new cable interruption monitoring and transformer temperature warning system combined fiber Bragg grating (FBG) with optical time-domain reflectometer (OTDR).This new system coupled with FBG, and the OTDR active detection of optical cable line is optimized to trigger monitoring of line interruption.It improves the shortcomings of traditional optical cable interruption detection system,such as short service life of OTDR, long response time and not supporting large-scale detection.In the state of no power supply,this joint monitoring system can realize temperature early warning of transformer and achieve response in seconds in the actual application scenario. | |||

Abstract:This paper proposes a large number of points temperature warning scheme based on the same wavelength fiber Bragg grating (FBG) string. The temperature warning experiment environment was established for experiment and a single-channel demodulator was used to obtain the wavelength shift of FBG. This scheme uses wavelength division multiplexing(WDM) technology to measure temperature. The results showed that the system can realize a temperature warning with an accuracy of about 3℃. | |||

Abstract:The paper reports the observation of the potential barriers’ influences on soliton spectral tunneling (SST) in photonics crystal fibers (PCFs) with three zero-dispersion wavelengths (ZDWs). The numerical simulations show that the generation of SST can be controlled well by regulating the parameters of the PCFs. Furthermore, the wave band and location of the switched solitons’ appearance can be controlled by adjusting the position of ZDWs. In addition, the leakage dispersive wave appears during this numerical simulations. This paper illustrate a new understanding of SST, it may provide some inspirations of applications in information security in the near future. | |||

Abstract:An optical network intermediate node scheme with format conversion of PAM4-to-QPSK signal is first proposed and simulated numerically. The input PAM4 signal is first converted into the two binary phase-shift keying(BPSK) tributaries based on optical nonlinearity and vector addition. The output quadrature phase-shift keying(QPSK) is generated through vector addition between two BPSK tributaries. One sub-channel BPSK tributary can be extracted from input PAM4 signal directly by using optical nonlinearity and vector superposition. When input PAM4 signal is pre-distorted to be the distorted PAM4 signal by self-phase modulation(SPM), another sub-channel BPSK tributary can be extracted from the distorted PAM4 signal by using optical nonlinearuty and vector superposition. For an input 10 Gb/s PAM4 with optical signal-to noise ratio(OSNR) of 30dB, the output QPSK gets 1.8% decrease in error vector amplitude(EVM), 3 dB receiver OSNR improvement at the bit error rate(BER) of 0.001 because of SPM-based amplitude regeneration. The proposed node scheme can be applied an all-optical interconnection node between different optical networks where different modulation formats are utilized individually. | |||

Abstract:With the emergence of new applications and development of Internet technology, the network capacity required is growing explosively. Elastic optical networks based on Space-Division Multiplexing(SDM) technology have become the research focus in order to cope with the capacity limitation of traditional single-mode fibers. Compared with the traditional routing and spectrum resource allocation problem, the introduction of space division multiplexing technology in optical networks brings about the problem of core allocation.In this paper, we propose a routing, spectrum and core assignment method with the dividing frequency slots area for space division multiplexing elastic optical networks. Simulation results show that by using this method, blocking probability can be reduced. | |||

Abstract:We propose and demonstrate in this paper all-optical simultaneous half-adder and half-subtractor in a single stage high nonlinear fiber (HNLF) operating with two data stream and a continuous probe light. Based on the nonlinear polarization rotation effects in HNLF, logic functions including the Sum/ Difference, Borrow and Carry are achieved at the same time. Operation with two 40 Gb/s NRZ-OOK data streams is experimental demonstrated and the logic functions are verified. This therefore leads to the advantage of reduced implementation complexity. Besides, the outputs of the half adder and half subtractor are linear polarized and located at single wavelength, which makes the presented logic gates suitable for cascading implementation. | |||

Abstract:A cost-effective and reliable optical pulse compression scheme was proposed and demonstrated experimentally. The proposed scheme is capable for single and multiple wavelength operation. The working bandwidth for the fixed device parameters was analyzed, and a range as large as 70 nm was achieved with good performance. A 0.98 ps ultra-short pulse for one channel and simultaneous 2.8,2.9,2.6 and 2 ps for 4-channels were obtained respectively. The high quality pulses were quite stable and no pedestal was observed. Further compression can be expected by adjusting the parameters. | |||

Abstract:A radio-over-fiber (RoF) link providing 60 GHz mm-wave signal using a 10 GHz RF signal source is proposed and simulated. According to our theoretical analysis of transmission performance of the signal, the scheme can eliminate the code form distortion caused by the sideband walk-off effect due to the fiber chromatic dispersion, and by adjusting the phase of the -2nd-order sideband, the influence of fading effect is removed. The numerical simulation results show that the radio-over-fiber (RoF) link with our generated optical mm-wave signal maintains good performance. | |||
