In the present embodiment, based on the data frame structure shown in Fig. 2, each Frame carry for indicating each Frame Including code word in position of first code word in transmission data serial number, can carry in the second code block, additionally, Second code block can also carry the number of codewords of at least one code word that LLID and each Frame include, LLID is used to identify ONU, i.e. mark data frame be generated by that ONU or transmission.Fig. 9 is referred to, Fig. 9 is one disclosed in the embodiment of the present invention Plant the schematic diagram of the second code block after extension.As shown in figure 9, the 0th and the 7th byte carries respectively starting and ending character, the 1st He 2nd byte is used to carry number of codewords of the bytes of LLID, the 3rd and the 4th for carrying FEC code, and the 5th and the 6th byte is used to hold Carry the serial number of first FEC code in Frame.
In the present embodiment, based on the data frame structure shown in Fig. 2, each Frame carry for indicating each Frame Including code word in position of first code word in transmission data serial number, can carry in the first code block, due to The effect of the first code block and the second code block is respectively the synchronization for completing synchronization and RS from scrambler, and the second code block is in actual applications It is also nonsensical, therefore, it can delete the second code block in Frame, and according to existing standard from scrambler multinomial, Complete scrambling code synchronization and only need to 58 bits, remaining 8 bits are also unnecessary, therefore, it is possible to use 8 ratios in the first code block Spy carries the serial number of first code word in Frame.Figure 10 is referred to, Figure 10 is another kind of number disclosed in the embodiment of the present invention According to the schematic diagram of frame.As shown in Figure 10, the first code block is only included in amended Frame, and does not include the second code block, 1 represents The serial number of first code word in transmission data in the corresponding Frame of first authorised channel, 3 represent the second authorised channels pair The serial number of first code word in transmission data in the Frame answered, 4 represent in the corresponding Frame of the first authorised channels the The serial number of one code word in transmission data.Figure 11 is referred to, Figure 11 is a kind of amended disclosed in the embodiment of the present invention The schematic diagram of the first code block.As shown in figure 11, amended first code block carries at least one yard that each Frame includes The serial number SN of first code word in transmission data in word.It can be seen that, because first code word only needs to include the first code block, no Need to include the second code block, it is thus possible to increase the digit of first code word carrying data, such that it is able to improve data transfer speed Rate.Additionally, the first code block can also carry the number of codewords of at least one code word that LLID and each Frame include,
In the present embodiment, the first code block and the second code block are the implementations of existing 10G EPON standards, are subsequently being marked In accurate implementation, if it is possible to have other modes to replace the function of the first code block and the second code block, then can be with Dispense the two code blocks.The FEC code type that at present standard is adopted for RS (255,223), the 66b64b's adopted in 10G EPON Line coding mode, FEC encoder is entered every time is all integer 66b code blocks, and the first two bit of each 66b code block is Synchronous head, only 01 and 10 two kind of value, therefore only need to protect 1 bit, each 66b code block is into FEC encoder All it is 65 bits.When each FEC code coding is carried out, 27 65 bit code blocks still reach to the payload needed less than code word, also 0 of the bit of polishing 29 before each code word is needed, 223 bytes then can be just gathered enough, FEC codings are carried out.FEC codings are completed Afterwards, the 0 of 29 bits of polishing can't be sent by physical layer, but directly be deleted, and receiving terminal is when row decoding is entered The 0 of the bit of first polishing 29 is required for, complete FEC code is gathered enough and is entered row decoding again.Therefore, each Frame carry for referring to Show the serial number of position of first code word in the code word that each Frame includes in transmission data, can carry at each Polishing position in Frame.For example, when the code word that each Frame includes is FEC code, can be in 29 bit polishing positions Take out a part to use as first FEC code serial number, ONU is by the serial number of first FEC code filling (padding) Mode be placed in the polishing position of 29 bits, FEC encoded after again 29 bit polishing positions deletion after be sent to by physical layer OLT.When OLT is decoded, the 0 of the bit of first polishing 29 enters row decoding, and polishing position is with first code word when sending data due to ONU Serial number, it is wrong pattern that decoder will detect polishing position, and carry out error correction to the pattern.As long as it is in FEC Within the scope of the error correction of pattern, OLT can just recover first code word sequence row number of ONU, and can utilize the serial number Carry out the restructuring of binding business.ONU in addition to it can carry the serial number of first code word, can also be carried in polishing position The information such as the number of codewords of at least one code word that LLID, each Frame include.In due to deleting first code word One code block and the second code block, therefore, the digit that first code word carries data is increased, such that it is able to improve data transfer speed Rate.
304th, at least two Frames are sent to OLT by ONU by corresponding authorised channel respectively.
305th, OLT obtains the serial number carried in each Frame, and according to the serial number for obtaining at least two data Frame is recombinated to obtain transmission data.
In the present embodiment, OLT is received after at least two Frames of ONU transmissions, will be obtained each Frame and be carried Serial number, afterwards according to obtain serial number at least two Frames are recombinated, to obtain transmission data.Work as Frame Quantity be 2, and the serial number that carries of the first Frame less than the serial number that the second Frame is carried when, the in transmission data One code word is first code word in the first Frame, when the serial number that the second Frame is carried is and the first Frame is carried Serial number adjacent next serial number when, second in transmission data code word is first code in the second Frame Word, when the next serial number that the serial number that the serial number that the second Frame is carried is not with the first Frame is carried is adjacent, Second code word in transmission data is second code word in the first Frame.
In the present embodiment, when each Frame also carry LLID and including at least one code word number of codewords when, At least two Frames can be recombinated according to the serial number, LLID and number of codewords that obtain, to obtain the biography of ONU transmission Transmission of data.Wherein, the serial number of at least one of each Frame code word is not necessarily continuous, for example:Transmission data Include 8 code words altogether, first Frame includes that 1,6 code words, second Frame include 2,5 code words, the 3rd Frame Including 3,8 code words, fourth data frame includes 4,7 code words.
In the data transmission method described by Fig. 3, ONU receive that OLT sends including at least two authorised channels and The uplink scheduling authorization of the mandate initial time of each authorised channel and mandate time span at least two authorised channels, according to The mandate initial time and mandate time span of transmission data and each authorised channel, corresponds with least two authorised channels At least two Frames, and at least two Frames are sent to into OLT by corresponding authorised channel respectively.At least two numbers Include at least one code word according to each Frame in frame, each Frame carries serial number, what each Frame was carried Serial number is used to indicate the position of first code word in the code word that each Frame includes in transmission data, when each data When frame includes two or more code words, the code word that each Frame includes is continuous in transmission data, therefore, it can lead to So that OLT realizes the restructuring at least two Frames by crossing the serial number of first code word that each Frame is carried, and Because each Frame only needs to carry serial number of the code word in transmission data, therefore, reduce in Frame and carry Serial number quantity, so that more data can be transmitted in Frame, so as to improve data transmission efficiency.Wherein, transmit Data are that ONU needs to be transferred to the data of OLT.
