Publication number: 20220045750Abstract: 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.Type: ApplicationFiled: October 12, 2021Publication date: February 10, 2022Inventors: Patrick Iannone, Michael Straub, Thomas Pfeiffer, Joerg Hehmann

Publication number: 20160072588Abstract: A method and apparatus for processing a communication signal in an optical network. A network node typically includes a transmit train for generating transmissions and a receive train for receiving transmissions from another network node. The network node may be, for example, an OLT or an ONU. In a receiver implementing the described solution, a photodiode is employed to convert received optical signals into electrical signals that are then provided to a TIA or other device for producing a differential output having an inverted output and a non-inverted output. One of the outputs is delayed one bit and attenuated, then combined with the other output to produce an equalized signal for further processing by the receive train. The solution may be analogously applied on the transmit side for introducing pre-distortion, either in addition to or in lieu of in the receiver.Type: ApplicationFiled: September 3, 2015Publication date: March 10, 2016Applicant: ALCATEL-LUCENT USA INC.Inventors: Vincent E.

Publication number: 20080112044Abstract: A multi-band hybrid amplifier is disclosed for use in optical fiber systems. The amplifier uses Raman laser pumps and semiconductor optical amplifiers in series to produce a relatively level gain across the frequency range of interest. Multiple Raman pumps are multiplexed before coupling into the fiber. The Raman amplified optical signal may be demultiplexed and separately amplified by the SOAs before remultiplexing. Gain profiles of the Raman pumps and the SOAs are selected to compensate for gain tilt and to alleviate the power penalty due to cross-gain modulation in the SOAs. The disclosed hybrid amplifier is especially useful in coarse wavelength division multiplexing (CWDM) systems.Type: ApplicationFiled: January 14, 2008Publication date: May 15, 2008Inventors: Patrick Iannone, Kenneth Reichmann, Xiang Zhou

Publication number: 20070212072Abstract: A method and system for upgrading service to an optical network terminal among a plurality of optical network terminals on a passive optical network. The upgrade enables bidirectional communications between a central office and the optical network terminal over dedicated downstream and upstream wavelength channels outside the downstream and upstream wavelength bands associated with the passive optical network. The optical network terminal to receive upgraded service is disconnected from a passive optical splitter at a remote node serving the optical network terminal, and optically coupled to a port of the multi-port arrayed waveguide grating at the remote node. Wavelength taps are provided at the central office and the remote node to facilitate multiplexing and demultiplexing the dedicated downstream and upstream channels with the downstream and upstream wavelength bands associated with the passive optical network.Type: ApplicationFiled: February 1, 2007Publication date: September 13, 2007Inventors: Patrick Iannone, Mark Feuer, Kenneth Reichmann, Kent McCammon
