Abstract
The invention is a forward error correction encoder, composed of a scrambling encoding module and a RS encoding module. Its character: the two modules are interlinked, data are sent out after two-stage coding and code-model adjusting. It can make system add network substation on the power limitation and can increase signal transmission distance on the noise limitation.
Description
Technical field:
The present invention relates to a kind of encoder, particularly a kind of forward error correction coder.
Background technology:
In the prior art, the coding that the ether optical access network is adopted can't be guaranteed the luminous power of each descending branch well.If just rely on the power that increases optical sender to solve the problems referred to above, not only can increase the cost of system, more can increase chromatic dispersion and nonlinear effect in the optical transmission.
Summary of the invention:
Technical problem to be solved by this invention is: in the prior art, the coding that the ether optical access network is adopted can't be guaranteed the luminous power of each descending branch well.If just rely on the power that increases optical sender to solve the problems referred to above, not only can increase the cost of system, more can increase chromatic dispersion and nonlinear effect in the optical transmission.The present invention provides a kind of forward error correction coder for the technical scheme that above-mentioned technical problem adopted that solves in the prior art, described this forward error correction coder is made of scrambler coding module and RS coding module, it is characterized in that described RS coding module outside is connected with a data buffer, described RS coding module links to each other with described scrambler coding module, described data buffer receives the outside data that send, and send data to described RS coding module, described RS coding module carries out the RS coding to the data that receive, and further data are sent to described scrambler coding module, described scrambler coding module carries out 8B10B sign indicating number coding to the data that receive, send to the outside after the adjustment of signal process sign indicating number type, concrete, described scrambler coding module outside is connected with synchronization module, described RS coding module adopts RS (255,239) coding, described scrambler coding module adopts seven grades of scramblers.
The present invention and prior art contrast, and effect is positive and tangible.Forward error correction coder of the present invention can make system increase light along separate routes under the limited situation of luminous power, and can increase signal transmission distance under the limited situation of Mode Partition Noise.
Description of drawings:
Fig. 1 is the high-level schematic functional block diagram of a preferred embodiment of forward error correction coder of the present invention.
Embodiment:
As shown in Figure 1, a kind of forward error correction coder of the present invention is made of scrambler coding module 1 and RS coding module 2, it is characterized in that described RS coding module 2 outsides are connected with a data buffer 3, described RS coding module 2 links to each other with described scrambler coding module 1, described data buffer 3 receives the outside data that send, and send data to described RS coding module 2,2 pairs of data that receive of described RS coding module are carried out the RS coding, and further data are sent to described scrambler coding module 1,1 pair of data that receive of described scrambler coding module are carried out 8B10B sign indicating number coding, send to the outside after the adjustment of signal process sign indicating number type, concrete, described scrambler coding module 1 outside is connected with synchronization module 4, described RS coding module 1 adopts RS (255,239) coding, described scrambler coding module 1 adopts seven grades of scramblers.Forward error correction coder of the present invention is applied to optical access network can make system increase light along separate routes under the limited situation of luminous power, and can increase signal transmission distance under the limited situation of Mode Partition Noise.
