Description

Technical field [0001] The present invention relates to optical wavelength division multiplexing technology in optical fiber communication, and specifically, to an optical wavelength division multiplexing system. Background technique [0002] In optical fiber communication, the technology that can transmit multi-wavelength optical signals simultaneously in an optical fiber is called optical wave multiplexing technology. In the process of optical fiber long-distance transmission, the optical fiber medium that needs to be transmitted is relatively long. If a light wave is transmitted by one optical fiber, a lot of optical fiber medium is required, which brings a lot of cost to people; since the introduction of optical wave multiplexing technology , We can transmit a variety of optical fiber signals in one optical fiber, which greatly improves the transmission efficiency. [0003] With the development of society, the demand for optical fiber transmission capacity in optical fiber tra...
