  • Method for converting wavelength of optical signal in passive optical network
    Patent number: 10128972
    Abstract: According to the present disclosure, a controlling unit arbitrarily determines a current set temperature of a temperature setting unit to cause a light generating unit connected to the temperature setting unit to generate an optical signal having a wavelength according to the current set temperature, thereby making it possible to effectively reduce a wavelength overlap phenomenon that may occur when a plurality of R-ONUs in a passive optical network simultaneously transmit the optical signals.
    Type: Grant
    Filed: January 25, 2018
    Date of Patent: November 13, 2018
    Assignee: Lightron Fiber-Optic Devices Inc.
    Inventors: Soo Yuk, Taek Hyung Kim, Young-Un Heo, Sung Jin Park
