【Abstract】 The paper quantitatively describes the relations between channel crosstalk, channel interval and channel bandwidth in high density optical wavelength division multiplexing transmission system through mathematical analysis, theoretically calculates the most channel numbers which multiplexed in various condition in single mode fiber low loss windows. Brief introduction is made to the performance measure of optical wavelength division multiplexers and optical wavelength division multiplexers which suited in different multiplexing transmission system.更多还原
