Title:
データ信号伝送装置およびデータ信号伝送方法
Document Type and Number:
Japanese Patent JP6876730
Kind Code:
B2
Abstract:
To provide a data signal transmission device and a data signal transmission method, capable of keeping, within an allowable range, a phase relationship between data signals at the inside of a transmission module.SOLUTION: A data signal transmission device 1 transmits data signals with phases aligned within an allowable range in a plurality of lanes from transmission modules 3 that are selectively installed in a plurality of slots 2 of a device body 1a. The data signal transmission device 1 includes: a body temperature measurement section 7 for measuring the ambient temperature of the device body 1a; a module temperature measurement section 8 for measuring the internal temperature of a transmission module 3 installed in the slot 2: a module information acquisition section 10a for acquiring module information of a transmission module 3 installed in the slot 2; a temperature correction processing section 10c for calculating a correction value of a variable delay element 9 of a transmission module 3 installed in the slot 2, on the basis of a preset correction coefficient for each of the transmission modules 3; and a variable delay control section 10d for correcting the delay amount of a variable delay element 9 of a transmission module 3 installed in the slot 2, on the basis of the correction value.SELECTED DRAWING: Figure 1
