摘要： A system and method for a transparent WDM metro ring architecture in which optics enables simultaneous provisioning of dedicated wavelengths for high-end user terminals, while low-end user terminals share wavelengths on “virtual rings”. All wavelengths are sourced by the network and remotely modulated at customer “End Stations” by low cost semiconductor optical amplifiers, which also serve as transmission amplifiers. The transparent WDM metro ring architecture permits the communication of information and comprises a fiber optical feeder ring, at least one fiber optical distribution ring, a network node (NN), at least one access node (AN) said network node and said at least one access node connected via said fiber optical feeder ring and at least one end station (ES) connected via said fiber optical distribution ring to said at least one access node, wherein said user is attached to said at least one end station. A simple node that supports bi-directional propagation in transparent WDM metro architectures using “virtual rings” is also described. A method for communicating information over a WDM fiber optical ring network architecture in a metro access arena using one or more wavelengths, which can be shared by a plurality of user terminals, each user terminal coupled to an end station comprises the steps of sending downstream data packets, sending optical chalkboard packets consisting of ones and sending control signals.

摘要： An optical telecommunications network suitable for carrying broadcast and switched services. The network includes a wavelength division multiplexing (WDM) coupled to a waveguide grating router (WGR). In accordance with the invention, an adjacent input port is connected with the same optical content. Thus, its outputs are adjacent (or wrapped around). According, the optical power in each of the broadcast bands at the outputs remains the same but is reduced by a factor of two in power for each channel but occupying twice as many channels. This has the effect of increasing the SNR by a factor of two.

摘要： A broadcast delivery system allows the delivery of broadband broadcast services over a WDM Passive Optical Network. These broadband services can be carried on optical broadband carriers or signals in a cost-effective manner by utilizing shared dispersion-compensated fiber (DCF) over a group of feeder lines or a group of PONs. A broadband optical signal is provided over a plurality of feeder lines. Each feeder line is connected to a remote node for distribution to subscribers. One dispersion-compensated fiber is shared for a plurality of feeder lines.

摘要： A passive optical network is provided that spectrally slices optical signals transmitted in both upstream and downstream directions utilizing wavelength division multiplexing routing. The passive optical network preferably includes a broadband optical signal source at both ends to provide signals that are spectrally sliced according to optical frequency. The downstream information may be transmitted in a conventional data format. The upstream transmissions may be segregated by subcarrier multiplexing, time scheduling or wavelength division multiplexing. At the subscriber end of the network there is an optical network unit which includes a device coupling the downstream fiber to the upstream fiber. Such coupling allows the passive optical network to perform enhanced diagnostic tests.

摘要： A multiple star implementation of RITE-Net.TM. type structure is implemented hereby. The structure provides an economical way of introducing PONs by serving a greatly increased number of subscribing ONUs for each fiber leaving the central office. Accordingly, the fiber gain reduces the installation cost of the fiber plant by reducing the average run length. Additionally, the larger number of subscribers reduce the average cost per subscriber for a laser at the central office.
