Abstract: A PON system comprising multiple PONs, each having a respective intelligent splitter monitor (ISM). In addition to having a passive optical splitter therein, an ISM also has several remotely powered active components configured to monitor the presence of uplink light signals on the ports of the splitter and communicate with the central office using out-of-band optical signals. These ISM functionalities enable the network operator, e.g., to automatically map PON connectivity, pairing each port on the splitter with a distinct optical network unit. The PON system further comprises an optical module connected to the multiple PONs through an optical switch in a manner that supports shared access to said module by the corresponding multiple ISMs. In an example embodiment, the optical module comprises an optical transceiver capable of communicating with the ISM transceivers and one or more lasers configured to provide high-intensity light for remotely charging the ISM batteries.

Abstract: A method, apparatus, and system for network monitoring, and more specifically for correlating downstream devices in an optical network with downstream ports of an optical splitter through which they are communicating with a central office. The downstream devices operational on the network are indentified and listed in a correlation table. Selected subsets of these devices are then monitored, preferably by an ISM under the direction of a management node, in a series of monitoring cycles until a satisfactory correlation may be achieved. The correlation cycle may be performed at startup, as needed, or on a periodic basis.

Abstract: Proposed is an optical data transmission device for an optical access network that comprises a laser transmission unit, which generates an optical transmission signal, and a driving unit, which controls the laser transmission unit for modulating the transmission signal. The device comprises an optical reception unit that converts the received optical signal into an electrical measurement signal. For this, the reception unit contains a photo-diode and an electrical amplifier. The optical reception unit is separate from the laser transmission unit. A control unit controls the laser transmission unit, such that the optical transmission signal is modulated in dependence on a measurement signal. The control unit measures multiple electrical measurement signals during a measurement interval and determines an averaged received electrical measurement signal.

Abstract: Proposed is a method of estimating a reflection profile of an optical channel. The method comprises different steps. A measured reflection profile of the optical channel is provided. One or more reflection peaks are estimated within the measured reflection profile. A residual reflection profile is determined, by removing the estimated reflection peaks from the measured reflection profile. Furthermore, a modified residual reflection profile is determined, by modifying one or more estimated crosstalk frequency components within the residual reflection profile. Finally, the estimated reflection profile is determined, by superposing the estimated reflection peaks and the modified residual reflection profile.

Abstract: The invention relates to a method for a telecommunication's network with a central office (CO), an access network, a multiple of demarcation point units (DPUn) and customer premises equipment (ONTn) connected thereto, to assign a customer premises equipment (ONTn) to a subscriber's data record registered in the central office (CO), where when a customer premises equipment (ONTn) reports the received signal amplitude in regular reporting intervals to the central office (CO), a customer premises equipment (ONTn) is assigned to a subscriber's data record by uniquely influencing the signal amplitude by the demarcation point unit (DPUn) assigned to the customer premises equipment (ONTn), the assignment of which to a certain subscriber's data record is known in the central office (CO), where the influencing of the signal amplitude is performed such that a digital signature proper to the demarcation point unit (DPUn) is imprinted on the signal amplitude, where the bit clock underlying the signature is adapted to the
