Abstract: A method of managing fault recovery in a trunk-branched OADM network may include determining that an optical power level over data channels of a first communications link between a first and a second terminal of the branched optical network exceeds an optical power limit. The method may further include increasing optical power sent over spare channels of the first communications link to a first level at which the optical power level over the data channels decreases to a second level below the optical power limit.

Abstract: Example management closures (110) enable incoming optical and/or electrical signals to be connected to one or more subscribers (109) via an electrical distribution cable (102). Termination connections within the management closure (110) are connected to active electronic equipment (131) for modifying and/or enhancing the incoming signals. However, the connections between the central office (101), the active electronic equipment (131), and a subscriber (109) need not be made until the subscriber requests a service upgrade. Accordingly, the closure (110) allows for simple and low cost installation of the closure (110) before upgraded service is needed.

Abstract: Powering an active/splitter and providing information to ONUs to cause adjustments to ONU operating wavelengths. An ONU may identify the port of a splitter to which the ONU is connected in order to make wavelength adjustments. Various techniques enable the ONU to identify from which port the ONU is receiving signals, such as a splitter that splits signals to ONUs in a cable network and signals to one or more ONUs the port to which it is connected. The splitter may lack electrical power and may perform the signal function by harvesting optical power from optical power provided to the splitter. In this manner, an active splitter may behave passively with respect to powering components in the absence of electrical power.
