BI-DIRECTIONAL MODULE OF COARSE WAVELENGTH DIVISION MULTIPLEXING

摘要

The present invention relates to a bi-directional module of coarse wavelength division multiplexing. The bi-directional module of coarse wavelength division multiplexing includes an output diode receiving an optical signal from the outside and outputting the received optical signal; an optical fiber which is an optical path for transmitting the optical signal outputted from the output diode; a bi-directional collimator collecting the optical signal transmitted by the optical fiber; an input diode receiving the optical signal introduced to the bi-directional collimator; and a filter positioned between the bi-directional collimator and the input diode and filtering a wavelength of the optical signal introduced to the bi-directional collimator, wherein the filter divides a wavelength with an error range of 2 nm, starting from a center wavelength. A wavelength of a bandwidth from 1270 nm to 1610 nm can be divided into 54 channels, thereby transmitting and receiving large capacity, high speed data.
