RSOA CONTROL METHOD AND A CONTROL DEVICE IN LOOP BACK TYPE WDM-PON OF AN RSOA BASE

摘要

PURPOSE: An RSOA control method and a control device thereof are provided to keep constant optical property driving RSOA of ONU(Optical Network Unit) regardless of the wavelength of the seed light inserted in the OLT in loop back type WDM-PON based on RSOA.;CONSTITUTION: A controller unit(10) controls the operating temperature activating the RSOA, and sets the threshold current in which the light source begins to erupt regardless of the wavelength of the seed light. An optical property control unit(20) controls the operating current in order to constantly control the light characteristic differently outputted by wavelength of the seed light inserted in RSOA. The optical property control unit comprises the current optical output information generator unit generating the current optical output information and the operating current setting unit setting the operating current which regularly controls the optical output characteristic.;COPYRIGHT KIPO 2010
