| After years of optical fiber communication development, the system transmission rateincreases, at the same time the transmission capacity has also made progress greatly.Nowadays, the transmission distance has expanded from tens of kilometers to hundreds ofkilometers. But by its own materials, faster and larger capacity optical fiber optical signaltransmission over longer distances also reverse the forward speed, especially for long-distanceoptical fiber communication. There is no relay transmission distance more than300km, fiberloss over70dB, optical fiber transmission-related indicators have been unable to meet thequality requirements of substation communication, the traditional non-relay technology hasencountered a bottleneck, need to rely on new fiber-optic communications technology to meetthe longer distance information transmission requirements.Optical distance information transmission in the conventional technique requires a largenumber of optical relay station construction, the purpose is to collect and amplify the opticalsignal. However, the establishment of optical relay station will increase the scale ofinvestment in the grid, once the optical relay station fails; the communication betweensubstations will be interrupted, affecting the normal operation of the grid. Therefore, there isneed to study the new fiber optic transmission, to minimize optical relay station set-point ofthe optical signal for transmission.In the paper, the author builds remote pump model, uses simulation test method fortransmission over a distance of300km non-relay optical transmission system, compared withthe normal indicators, validated research findings to solve part of Xinjiang Power Grid longdistance optical fiber communication stations seting up difficult, operation and maintenancedifficult problem. The results of this thesis on the future of Xinjiang Power Grid non-relayoptical transmission network have a certain reference value and profound impact for remotepump technology. |
