The following optical transport network development, IBM propose that " the wisdom earth " theory has caused the construction of Chinese " smart city ", band
Come the ground such as the development Beijing Today Guizhou of big data industry and just build scale, therefore the big data transaction platform that has been born, but big number
According to the overlong time of transmitting, such as individually, a pair of optical fiber traditional equipment SDH 2.5Gbit/s transmitting needs can incite somebody to action for more than 400 seconds
1.0Tbit/s signal is transferred to distal end.More big data packet if it is > 1.0Tbit/s is exactly to install configuration equipment additional, transmission pressure
Power is very big, therefore hits since " Dian " the moment to complete this event, it is desirable that The faster the better.Current passing time is all very long,
Nowadays it is even more that " strategic resource " improves big data trading capacity and accelerate big data transmitting speed that big data, which is not only " economic rich ore ",
It is imperative to spend.
﹡ 5G will make thousands of times of base station communication capacity of increase, and SDN again idealizes cloud " cloud " data center, move
It is motionless with regard to 100,000 virtual machine cloud services, how fearful it is, therefore fiber optic network transport layer that the interchanger of 100,000 MAC, which works at the same time,
It wants on root it and adapts to it, it is necessary to the ability of real-time vast capacity superelevation rate and ultra-long span transmission, the requirement quickly transmitted
With regard to very necessary, but the main reason for current optical-fiber network is not caught up with is that dispersion accumulation makes limited transmission distance, and transmission rate is not high,
According to formula (1)
L=Dmax/D ... (1)
In formula: L-dispersion limit；
Dispersion (ps/nm) perhaps is filled between the end Dmax-S-R；
D-fiber dispersion coefficient (ps/nm.km)；
The abbe number of 1550nm is 16.5ps/nm.km
So: the dispersion representative value of 2.5Gbit/s is 11000ps/nm, dispersion limit 640km；
The dispersion representative value of 10Gbit/s is 1000ps/nm, dispersion limit 60km；
And the dispersion representative value of 40Gbit/s is 50ps/nm, the dispersion of 160Gbit/s requires smaller only 5ps/nm, because
This needs to accurately control dispersion compensation.And China will build " unified time frequency reference fiber support net platform " that this is special
General character application supporting network platform provides high-precision and superhigh precision Time and frequency standard for optical fiber transmission network, to fibre-optical dispersion
It can be effectively controlled, " unified time frequency reference fiber support net platform " is relied on to pass through the quick transmission technology of several massive dataflows
Patent is to be easily achieved big data transmitting.
