Submarine Optical cable is laid on seabed, point submarine communication cable and seabed luminous power optical cable with the bundle conductor of insulation sheath parcel.The former is mainly used in communication traffic, and the latter is mainly used in the high-power luminous energy of underwater transmission.Compared with artificial satellite, submarine optical fiber cable has a lot of advantage: seawater can prevent the interference of ambient light magnetic wave, so the signal to noise ratio (S/N ratio) of extra large cable is higher; Experience in sea floor optoelectronic cableless communication less than time delay; The designed life of Submarine Optical cable is continuous firing 25 years, and artificial satellite generally will be used up by fuel in 10 to 15 years.
The structural requirement of Submarine Optical cable is firm, material light, but can not use light metal aluminium, because aluminium and seawater electrochemical reaction can occur and produce hydrogen, hydrogen molecule can be diffused in the glass material of optical fiber, makes the loss of optical fiber become large.Therefore Submarine Optical cable should prevent inner generation hydrogen, also will prevent hydrogen from infiltrating optical cable from outside simultaneously.For this reason, the phase in the early 1990s, develop a kind of optical fiber being coated with carbon or being coated with titanium layer, the infiltration of hydrogen can be stoped and prevent chemical corrosion.Fibre-optical splice also requires it is high strength, and requiring continues keeps the surface of the intensity of original optical fiber and original optical fiber injury-free.
At present, Submarine Optical cable and the larger optical cable of other rigidity are just widely used in data communication industry, the fields such as electric power transfer industry, but the pick-up unit of its twist stiffness and detection method still belong to blank at home.
