Optical access system, bureau side terminating set and member side terminating set

摘要

OLT1 and ONU2 (2 1 - 2 m) with, with being the optical access system which is formed, OLT1 descends and has the CP removal section vis-a-vis 11 which removes CP from the rising signal which is received from the CP insertion section 10 which inserts CP in the signal and ONU2 and the rising CP removal signal the FFT section 13 which does the equalization processing with frequency domain equalization system on the basis of the opposite quality of the transmission line quality to ONU2, EQ section 14 and opposite FFT section 15 and, the CP insertion section 10 where inserts CP ONU2 rises and vis-a-vis the signal and, from the descent signal which is received CPThe FFT section 13 which does the equalization processing with frequency domain equalization system on the basis of the opposite quality of the transmission line quality to OLT1 which has been kept the CP removal section vis-a-vis 11 which is removed and the descent CP removal signal, EQ section 14 and opposite FFT section 15 and, it has.
