TL;DR: In this paper, the authors proposed an optical distribution shelf for providing both narrowband telephony signals and broadband video services over a single optical fiber using a single Optical carrier, which includes a plurality of optical distribution units and interface units for interfacing with a controlling microprocessor.
Abstract: In an optical fiber telecommunications network for providing both narrowband telephony signals and broadband video services over a single optical fiber using a single optical carrier, an optical distribution shelf includes a plurality of optical distribution units and interface units for interfacing with a controlling microprocessor. The optical distribution units receive baseband TDM telephony signals in serial format and the broadband video signals and function to frequency division multiplex the broadband video signals with the baseband telephony signals. The multiplexed signal is used to frequency modulate an optical carrier for transmission on a single optical fiber.

01 Dec 1999TL;DR: This work investigates and compares different distributed control mechanisms for establishing all-optical connections in a wavelength-routed WDM network and provides updates to reflect which wavelengths are currently being used on each link.
Abstract: In wavelength-routed WDM networks, a control mechanism is required to set up and take down all-optical connections. Upon the arrival of a connection request, this mechanism must be able to select a route, assign a wavelength to the connection, and configure the appropriate optical switches in the network. The mechanism must also be able to provide updates to reflect which wavelengths are currently being used on each link so that the nodes may make informed routing decisions. We investigate and compare different distributed control mechanisms for establishing all-optical connections in a wavelength-routed WDM network.

TL;DR: ADRENALINTE testbed is presented, an SDN/NFV packet/optical transport network and edge/core cloud platform for end-to-end 5G and IoT services.
Abstract: The fifth generation of mobile networks (5G) and the internet of Things (IoT) impose very stringent requirements to the optical transport networks. On the one hand, high flexibility, ultra-low latency and high capacity, in order to support the forecasted 1000x growth in mobile data traffic with latencies below millisecond. On the other hand, massive edge and core cloud infrastructure integrated with the transport network to dynamically deploy NFV, MEC, and IoT analytics. This paper presents ADRENALINTE testbed, an SDN/NFV packet/optical transport network and edge/core cloud platform for end-to-end 5G and IoT services.

24 Apr 1996TL;DR: In this article, a method and apparatus for optical signal routing in an optical network that includes one or more optical fibers to carry multiplexed signals is described, which includes an optical wavelength division demultiplexor to demultiprocessor to transform the signals into signals based on wavelength.
Abstract: A method and apparatus for optical signal routing in an optical network that includes one or more optical fibers to carry multiplexed signals. Each optical fiber may include a plurality of optical carriers with each optical carrier operating at a different wavelength. The optical network includes an optical network routing apparatus to receive the multiplexed signals from the optical fiber, to categorize the multiplexed signals as local signals or as non-local signals, to drop the local signals to a local switch, and to transmit the non-local signals to the optical fiber for further routing in the optical network. Advantageously, the transport of multiplexed signals on optical carriers of different wavelengths on a single optical fiber multiples by the number of optical carriers the bandwidth capacity of the optical fiber. Further, the optical network routing apparatus routes signals through the optical network, routes signals to a local switch associated with the optical network, and/or adds signals from the local switch to the optical network. The optical network routing apparatus includes an optical wavelength division demultiplexor to demultiplex multiplexed signals into signals based on wavelength. A type check categorizes the signals as local signals or as non-local signals. The type check transmits the local signals to a local switch based on signal type and/or wavelength. The type check also transmits the non-local signals to an optical wavelength division multiplexor, which multiplexes the non-local signals for further routing through the optical network.

TL;DR: In this paper, a WDM PON performs bi-directional communications, and includes an interface, where the interface transfers one or more signals having a first platform to the WDM-PON data transmission platform at an access point of a network to propagate through a single transmission medium.
Abstract: Wavelength division multiplexing (“WDM”) passive optical networks (“PON”) to transport signals having various access platforms are described. For one embodiment, a WDM PON performs bi-directional communications, and includes an interface. The interface transfers one or more signals having a first platform to a WDM-PON data transmission platform at an access point of a network to propagate through a single transmission medium, to one or more remote distribution nodes in between a Central Office and an optical network unit. The single transmission medium carriers three or more optical channels traveling in both directions.
