  • Publication number: 20150350755
    Abstract: A manner of performing remote-node management, for example the management of ONUs in a PON. In that type of optical network, a management node such as an OLT determines that a management command is to be transmitted and also determines the management protocol associated with the management command. A management message is generated, the management message having a header with a device identifier field. When the management message is generated, the device identifier field is populated with a value indicating whether the management command is associated with a default protocol or with an alternate protocol. The value in the device identifier field may identify specific alternate protocols so that when the manage device, for example an ONU in a PON, received the management message it may be directed to an appropriate interface point.

  • Patent number: 9185555
    Abstract: An apparatus comprising a first passive optical network (PON) component configured to couple to a second PON component via an optical link and authenticate the second PON component based on authentication information to authorize a backup wireless link between the first PON component and the second PON component. The backup wireless link corresponds to a wireless backup system for the PON. The authentication information is associated with an identifier of the wireless backup system. Also included is a network component comprising a first passive optical network (PON) component configured to receive authentication information for a wireless backup system for a PON from a second PON component and compare the authentication information to expected authentication information at the first PON component to authorize a wireless link between the first PON component and the second PON component for the wireless backup system.
