Independently routable digital subcarriers with configurable spacing for optical communication networks

Abstract: Optical network systems and components are disclosed, including a transmitter comprising a digital signal processor receiving a plurality of independent data streams, and supplying a plurality of digital subcarrier outputs, based on the plurality of independent data streams, and configurable to vary the frequency spacing between two or more of the plurality of digital subcarrier outputs; the transmitter configured to output a modulated optical signal including a plurality of optical subcarriers based on the digital subcarrier outputs wherein based on first ones of the plurality of digital outputs, the first one of the plurality of subcarriers is spectrally spaced from the second one of the plurality subcarriers by a first gap, and based on second ones of the plurality of digital outputs, the first one of the plurality of subcarriers is spectrally spaced from the second one of the plurality of subcarriers by a second gap different than the first.

System Innovations in Inter Data Center Transport Networks

Abstract: We review the most important WDM DCI system innovations. State-of-the-art coherent transmission has already exceeded 6 b/s/Hz, using subcarrier modulation. The adoption of software innovations in automation and programmability, that DCI pioneered in transport networks, has also simplified operations and enables the emergence of “open” transport architectures. Combining these advancements with emerging network analytics frameworks allows exciting innovations in network design and management optimization.

Dual-level package

Abstract: Consistent with an aspect of the present disclosure, a package is provided that has a carrier and first and second substrates provided on the carrier. Conductive traces are provided on the first substrate (upper traces) and below it (lower traces) to provide two levels of electrical connectivity to a photonic integrated circuit (PIC) provided on the second substrate. As a result, an increased number of connections can be made to the PIC in a relatively small package, while maintaining adequate spacing and line widths for each trace. In addition, the lower traces are connected to bonding pads on the surface of the first substrate and are thus provided in the same plane as the upper traces. Testing of and access to both upper and lower traces is thus simplified.

Apparatus and method for optimizing an iterative FEC decoder

Abstract: Consistent the present disclosure, errored bits are inserted into a data stream, which is carried by an optical signal The optical signal is transmitted over an optical link that may induce additional errors, ie, add additional errored bits to the data stream At the receive end, the optical signal is converted into a corresponding electrical signal that carries the data stream The data stream is subject to forward error correction (FEC) decoding with an iterative decoder, for example The iterative decoder decodes the data stream over a number of iterations until both the inserted errored bits and the additional errored bits are corrected Since the number of inserted bits is known, the number of iterations required to correct the inserted bits is also known (“first iterations”) Accordingly, the number of iterations required to correct the additional errored bits caused by transmission over the optical link may be determined based on the total number of iterations performed and the number of the first iterations

Automatic network-wide service configuration system and method

Abstract: Systems and methods are disclosed including a method comprising: receiving, with a controller having a computer processor, a preservation status input from a user indicative of whether or not to preserve a virtual local area network (VLAN) tag in a header of a data packet transmitted within an Ethernet local area network (E-LAN), the VLAN tag identifying at least one of customer information and service provider information for the data packet in the E-LAN, wherein the E-LAN comprises network devices having physical ports and is configured to allow multiple customers use of an individual physical port; determining a scalable network-wide service configuration model having multiple predetermined rules for automatically configuring the physical ports of the network devices for the E-LAN based on the preservation status input from the user; and configuring automatically, with the controller, the physical ports of the network devices using the predetermined rules of the configuration model.
