Title: Joerg Hehmann: Innovator in Optical Network Technologies

Introduction

Joerg Hehmann is a notable inventor based in Weil der Stadt, Germany. He has made significant contributions to the field of optical networks, holding three patents that showcase his innovative approach to technology.

Latest Patents

Hehmann's latest patents include a system for monitoring multiple passive optical networks (PONs). This PON system comprises multiple PONs, each equipped with an intelligent splitter monitor (ISM). The ISM not only contains a passive optical splitter but also features several remotely powered active components. These components are designed to monitor uplink light signals on the splitter's ports and communicate with the central office using out-of-band optical signals. This functionality allows network operators to automatically map PON connectivity, linking each port on the splitter with a distinct optical network unit. Additionally, the PON system includes an optical module connected to the multiple PONs via an optical switch, facilitating shared access to the module by the corresponding ISMs. In one embodiment, the optical module features an optical transceiver capable of communicating with ISM transceivers and includes lasers for remotely charging the ISM batteries.

Another significant patent by Hehmann is an apparatus and method for optical-network monitoring. This invention focuses on correlating downstream devices in an optical network with the downstream ports of an optical splitter. The method involves identifying and listing the downstream devices operational on the network in a correlation table. Selected subsets of these devices are monitored, preferably by an ISM under the direction of a management node, through a series of monitoring cycles until satisfactory correlation is achieved.
