摘要： The present technology relates to a data processing device and a data processing method which can ensure high communication quality in data transmission using LDPC codes, in group-wise interleaving, an LDPC code having a code length N of 64800 bits and a coding rate r of 13/15 is interleaved in a unit of a bit group of 360 bit. In group-wise deinterleaving, a sequence of bit groups of the LDPC code which has been subjected to the group-wise interleaving is returned to an original sequence, the present technology can be applied to, for example, a case in which data transmission is performed using LDPC codes.

摘要： An optical transmission module according to the disclosure comprises a first optical transmission line, a second optical transmission line, and a ferrule. The first optical transmission line has a first end face. The second optical transmission line has a second end face opposed to the first end face of the first optical transmission line. An end of the first optical transmission line is situated inside the ferule, and the ferule has a light-transmittable intermediary portion situated between the first end face and the second end face.
