Information (ocean temperature, pressure etc.), is transmitted to terrestrial base station monitoring center by bone optical fiber net.
Box of plugging into is a terminal, uploads to bank base by optoelectronic composite cable again after various data are carried out processing separation
It stands.
In long-distance optical fiber transmission, there are some problems.First point, G.652 optical fiber 1550nm window mean attenuation coefficient
For 0.20dB/km, after 100kM, it is being lost as 20dB, i.e. power is reduced to 1 percent.That is, on the line
The signal power of transmission can gradually decay, and will cause distorted signals when decaying to a certain extent, thus will lead to reception mistake, special
It is particularly evident when being not long distance transmission.Second point, fibre-optical dispersion are also the principal element for influencing transmission performance.Standard single mode light
Fine abbe number is 17ps/ (nm km), if it is considered that common 10Gbit/s signal, then maximum transmission distance is no more than
100kM。
The settling mode generally used at present is to add repeater or fiber amplifier, although greatly extending data transmission
Distance, but it is with high costs, lay it is difficult.
