Title:
METHOD FOR MEASURING CROSSTALK OF LIGHT RECEIVER
Document Type and Number:
Japanese Patent JP2000356571
Kind Code:
A
Abstract:
To provide a method for measuring crosstalk between channels in a multichannel light receiver using a direct current connection light receiver circuit capable of light receiving of direct current level.
In both states that crosstalk exists (a) and crosstalk does not exist (b), digital light signals having light levels of two values, emission level and quenching level in the channel to be measured are input. For each state, by measuring the amplitude of light signals fulfilling a specific condition such as erroneous sign, crosstalk is measured.
