摘要： A burst-mode laser control circuit and related methods thereof are disclosed. Using an APC loop with an additional burst-mode control circuit, and a switch in series with a diode and in parallel with the laser, a continuous-mode laser driver is enabled to operate in burst-mode by turning the switch on or off via external logic. Burst-mode control manages the switch, and a bandwidth-select circuit using a high or low logic level input, wherein the laser is disabled and the bandwidth-select circuit enters a fast-track mode when the external logic signal has a first level. The laser provides regular optical signals, and the bandwidth-select circuit enters a slow-track mode, thereby enabling the APC loop to operate normally, when the external logic signal has a second level. In addition to a low cost and simple implementation, the control circuit and method provide lasers with a fast response capability using one or more externally-controlled switch circuits to meet demands of PON systems for burst-mode ONUs.

摘要： A DC level detection circuit between high speed signal line connecting ports and a system using the same in optical communications is disclosed. Corresponding ports of a high speed signal line each have an additional resistor, where one additional resistor has a resistance significantly greater than that of the other resistor. The smaller resistor is grounded. The larger resistor is connected to a DC voltage source, a low pass filter, and a signal detection port. Thus, when both ports of the high speed signal line are connected, a status of the electrical level detected at the signal detection port changes. The circuit detects the connection state of the high speed signal line without negative effects on signal transmission and is applicable to various circuits, especially plug-in modules and corresponding slots. Thus, the circuit further enables signal port multifunctionality, increases module installation accuracy, and provides higher compatibility for plug-in modules.
