The communication and control system of an oilfield in the South China Sea has been modified and optimized in order to complete the remote control production of an offshore oilfield during typhoons. The oilfield communication antenna is equipped with glass fiber reinforced plastic sheath to reduce the vibration of satellite antenna caused by strong winds. The oilfield thermal backup and terminal power amplifier ensure continuous connection. Through the remote control transformation of on-site equipment, control system optimization, the construction of land remote monitoring center and other ways to complete the remote control of production during the typhoon. Meanwhile, through the automatic control of one-button seawater displacement function to ensure the replacement of pipelines after the production of oil fields, fire and gas fire fighting system during the typhoon production is still normal operation, to ensure the safety of on-site equipment. In the process of typhoon remote control, due to the remote communication control, there is a certain delay, the operator needs to minimize the man-machine interface of the operation control system, and try to make the equipment run automatically. The stable operation of typhoon remote control production is ensured through the transformation and optimization of the oilfield.

“…In recent years, with the development of the Internet, the volume of global information has grown exponentially, which poses a huge challenge to the existing communication networks [1] . The current communication system based on single-core single-mode fiber, whose communication capacity is basically approaching the limit of Shannon, can no longer meet the demand for the massive growth of communication services.…”

We experimentally transmit eight wavelength-division-multiplexing (WDM) channels, 16 quadratic-amplitude-modulation (QAM) signals at 32-GBaud, over 1000 km few mode fiber (FMF). In this experiment, we use WDM, mode division multiplexing, and polarization multiplexing for signal transmission. Through the multiple-input-multiple-output (MIMO) equalization algorithms, we achieve the total line transmission rate of 4.096 Tbit/s. The results prove that the bit error rates (BERs) for the 16QAM signals after 1000 km FMF transmission are below the soft-decision forward-error-correction (SD-FEC) threshold of 2.4 × 10 −2 , and the net rate reaches 3.413 Tbit/s. Our proposed system provides a reference for the future development of high-capacity communication.

“…The C-band and the O-band are indeed the predominant frequency bands in optical communication systems. However, selective frequency fading due to chromatic dispersion significantly limits the transmission distance of high-speed digital links, driving the need for high-performance optical amplifiers [ 6 ]. Moreover, coherent light enables linear frequency conversion of the entire optical signal into a baseband electrical signal, better fulfilling the bandwidth requirements of optical networks [ 7 ].…”

Polarization-insensitive semiconductor optical amplifiers (SOAs) in all-optical networks can improve the signal-light quality and transmission rate. Herein, to reduce the gain sensitivity to polarization, a multi-quantum-well SOA in the 1550 nm band is designed, simulated, and developed. The active region mainly comprises the quaternary compound InGaAlAs, as differences in the potential barriers and wells of the components cause lattice mismatch. Consequently, a strained quantum well is generated, providing the SOA with gain insensitivity to the polarization state of light. In simulations, the SOA with ridge widths of 4 µm, 5 µm, and 6 µm is investigated. A 3 dB gain bandwidth of >140 nm is achieved with a 4 µm ridge width, whereas a 6 µm ridge width provides more output power and gain. The saturated output power is 150 mW (21.76 dB gain) at an input power of 0 dBm but increases to 233 mW (13.67 dB gain) at an input power of 10 dBm. The polarization sensitivity is <3 dBm at −20 dBm. This design, which achieves low polarization sensitivity, a wide gain bandwidth, and high gain, will be applicable in a wide range of fields following further optimization.
