    摘要: A method for optical signal amplification in an optical communication system is presented. The optical communication system comprises an optical line terminal, a plurality of optical network units, an optical splitter and a plurality of circulators. The optical network units comprise each an optical amplifier. A first optical signal is sent in a downstream direction from the optical line terminal to a first circulator from the plurality of circulators. The first optical signal is further sent from the first circulator to a first optical network unit from the plurality of optical network units and it bypasses the optical splitter. The first optical signal is amplified in the optical amplifier of the first optical network unit to generate an amplified optical signal.

    摘要: An assembly (100, 220, 300) that includes a laser diode (110, 310) and a driver circuit (120) that operates to give the assembly an (100, 220, 300) adjustable impedance. The driver circuit (120) adjusts impedance by repeatedly alternating between two operational phases (131,132). In one operational phase (131), current is primarily or fully supplied through the laser diode (110, 310) using a first current path (151) being from the first supply node (121), to the laser diode (110, 310), and into the second supply node (122). In the other operational phase (132), current is supplied through the laser diode (110, 310) using a recirculating second current path. The current through the laser diode increases during the first operational phase (131), and decays during the second operational phase (132). For a given applied voltage level between the first and second supply nodes (121, 122), the duty cycle (D1, D2) of the first and second operational phases (131, 132) may be adjusted so that the current through the laser diode (110, 310) is approximately a target current.
