METHOD AND SYSTEM FOR CONTROLLING DRIVING CURRENT OF WDM-PON OPTICAL TRANSMITTER |
摘要 |
The present disclosure relates to a WDM-PON (wavelength division multiplexed-passive optical network) optical transmitter; and, more particularly, to a system for controlling driving current of the WDM-PON optical transmitter. The present disclosure provides a driving current control method of the optical transmitter for in use in the WDM-PON, including: setting an attenuation value of a variable optical attenuator to X; detecting an optical power Px received by a monitoring photo diode of the optical transmitter; setting an attenuation value of the variable optical attenuator to Y; detecting an optical power Py received by the monitoring photo diode of the optical transmitter; calculating an optical power Pout of an optical signal outputted from a common terminal of a 1×N optical multiplexer/demultiplexer based on the detected optical power Px and Py; and controlling a driving current based on the calculated optical power Pout.
