摘要： Example embodiments include an optical networking system (e.g., apparatus) and corresponding method. According to some embodiments, a plurality of shelves may be interconnected to form a daisy chain, each shelf including unpowered passive optical modules and the daisy chain including an active module having a passive power communication source. The passive power communication source may distribute passive power to memory devices on the one unpowered passive optical networking modules. The memory devices may provide respective communication as a function of interconnections of the daisy chain and passive power distributed by the passive power communication source. Advantages include unique identification of the memory devices without requiring active power to their corresponding modules, and continuous discovery and inventory of such memory devices. Such embodiments may also help network planners better manage and end-to-end optical circuit which may reduce amplification or regeneration nodes creating a more cost efficient solution.

摘要： Example embodiments are in a form of a system, corresponding electronics card (or apparatus), or corresponding method. Some embodiments include a multi-channel optical layer system. According to some embodiments, the system may include a network interface layer, an adapter layer, and an optical function layer. The adapter layer may learn functions and/or corresponding specifications from the function layer. The adapter layer may configure the adapter layer itself to interoperate between the network interface layer and the optical function layer. The adapter layer may provide flexibility in the size of configured functionality. The adapter layer may reduce cost of configuration (or reconfiguration) because functions may be discretized. New markets may be reached because of this reduced cost, as well as due to smaller size configurations (of hardware and software), reduced electronics, reduced power, and improved thermal cooling requirements for lesser-developed network configurations.

摘要： The disclosed methods, apparatus, and systems allow safe and easy deployment of amplifier products that exceed laser safe limits without the need for fiber testing and characterization or OTDR techniques. One example embodiment is a method for ensuring eye safety in an optical network. The example method includes detecting optical connectivity between an output of a transmit amplifier and a passive optical processing element. The transmit amplifier is located at a first network node and is configured to output optical power greater than eye-safe level. The passive optical processing element is located at a second network node and is configured to guarantee a reduction of a maximum optical power level at an output side of the passive optical processing element to an eye-safe optical level. The detecting occurs at the first network node, and the transmit amplifier is enabled or disabled as a function of detection of the optical connectivity.
