Abstract: Disclosed herein are methods and systems for routing traffic. One exemplary system includes a muxponder module deployed in an optical network, the muxponder having an optical receiver, a first and second electrical port, a demultiplexer having a built-in digital cross-connect, and a processor accessing a first calculated carrier frequency to assign traffic streams associated with a first service identification code to a first and second host lane of the first electrical port, and a second calculated carrier frequency to assign traffic streams associated with a second service identification code to a third and fourth host lane of the second electrical port, and having logic to control the digital cross-connect to route a first and a second traffic stream to the first electrical port based on the first service identification code, and a third and a fourth traffic stream to the second electrical port based on the second service identification code.

Abstract: Optical subcarriers may be employed to transmit data in a point-to-multi-point network whereby a hub node including a network switch receives such data from a client and transmits information indicative of such data to multiple leaf or network nodes, where data intended for such leaf node is output. Often the rate at which data is supplied to the hub node is different than the rate at which information indicative of the data is transmitted. Moreover, the client data may have a format that is different than that associated with the transmitted information indicative of the client data. Consistent with the present disclosure, client data is inverse multiplexed to lower data rate streams and then multiplexed to a plurality of inputs, each of which corresponding to a respective optical subcarrier. Information indicative of the data may be allocated to multiple subcarriers, if the a single carrier lacks sufficient capacity or bandwidth to meet the bandwidth requirements of the leaf node.

Abstract: Implementations for remotely managing an optical transceiver connected to a network device and optical network is described. A user can use a network device controller and optical transceiver controller in a remote server to communicate with the service agent in the network device and the optical transceiver to configure communications with the optical network through the optical transceiver. The service agent and its controller in the server can perform virtualized transport functions and the network device controller and the network device can, in some instances, implement layer 2/3 demarc.

Abstract: An optical system is provided comprising a first node and a channel drop add device. The first node is configured to transmit data onto an optical fiber in a first line direction. The channel drop add device (501) is adapted to receive and add channels onto the optical fiber thereby transmitting the data into the first and a second line direction. The network further comprises a second node configured to form a transmitter/receiver function. The second node is configured to receive data on said optical fiber from said first and second line directions. Further, the second node is adapted to synchronize received data from said first and second line directions by delaying the data signals seeing the shortest delay, by a delay device.
