Abstract

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.
