Title:
光受信装置、マルチコア光ファイバ及び光伝送システム
Document Type and Number:
Japanese Patent JP5876266
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the processing load to eliminate crosstalk in an optical transmission system using multicore optical fiber.SOLUTION: An optical receiving device 15 of the present invention comprises: a photoelectric conversion unit 151, having a multicore optical fiber 13 connected thereto, which receives channel signals from the multicore optical fiber 13; a crosstalk amount storage unit 154 which has fixedly stored therein amounts of crosstalk between channel signals as the nondiagonal elements of a channel matrix about channel signals; and a crosstalk elimination unit 153 which calculates the electric field or the strength of channel signals transmitted by an optical transmitting device 11 on the basis of the channel matrix about channel signals which includes the amounts of crosstalk between channel signals fixedly stored in the crosstalk amount storage unit 154 as nondiagonal elements, as well as the electric field or the strength of channel signals received by the photoelectric conversion unit 151.
