摘要： A system, apparatus and method are described for controlling the gain across one or more amplifier nodes within an optical span. In one embodiment, a fast local amplifier constant gain control loop is provided that maintains a constant gain across an amplifier node for each of the channels within an optical signal. A slow link level gain setting control loop is provided to set and/or adjust the target gain on the amplifier node(s). A gain adjust sequence is performed by the slow link level gain setting control loop to adjust the target gain(s) in response to various events and mechanisms. A "time of flight" protection method is also provided to ensure consistency between the fast local amplifier gain control loop and the slow link level gain setting control loop.

摘要： Optical autodiscovery is provide between two optical modules to insure that when an optical signal is coupled between the two optical module, the optical signal from a first module does not interfere with operation of a second module. The autodiscovery is implemented by sending an optical identification signal from the first optical module via the coupling to the second optical module from which signal, the second optical module can verify and determined acceptance of the coupled first optical module. During this autodiscovery process, the optical identification signal from the first optical module may be attenuated or shifted in optical spectrum so as not to interfere with the operation of the second optical module. Autodiscovery may also be employed in cases where a first optical module is to receive an optical signal from a second module.
摘要翻译：在两个光学模块之间提供光学自动发现，以确保当光信号耦合在两个光学模块之间时，来自第一模块的光信号不会干扰第二模块的操作。通过从第一光学模块经由耦合向第二光学模块发送光学识别信号来实现自动发现，第二光学模块可从该第二光学模块验证和确定耦合的第一光学模块的接受。在该自动发现处理中，来自第一光模块的光学识别信号可以在光谱中被衰减或移位，从而不会干扰第二光模块的操作。在第一光模块将从第二模块接收光信号的情况下也可以采用自动发现。

摘要： A digital optical network (DON) is a new approach to low-cost, more compact optical transmitter modules and optical receiver modules for deployment in optical transport networks (OTNs). One important aspect of a digital optical network is the incorporation in these modules of transmitter photonic integrated circuit (TxPIC) chips and receiver photonic integrated circuit (TxPIC) chips in lieu of discrete modulated sources and detector sources wit h discrete multiplexers or demultiplexers.

摘要： A laser source or a plurality of laser sources in a photonic integrated circuit (PIC) are provided with an electrical contact that is either segmented or is connected to a series of vernier resistor segments for supply of current to operate the laser source. In either case, at least one segment of the laser contact or at least one vernier resistor segment can be trimmed in order to vary the amount of current supplied to the laser source resulting in a change to its current density and, thus, a change in its operational wavelength while maintaining the current supplied to the laser source constant.
