摘要： In accordance with the present invention, optical channels to be demultiplexed are supplied to first and second optical fibers via an optical splitter. Low loss interference filters, for example, coupled to the first and second optical fibers, select respective groups of channels. Each group of channels is next demultiplexed with sub-demultiplexers into individual channels, each of which is then sensed with a corresponding photodetector. Although the optical splitter introduces an optical power loss at the input to the demultiplexer, the interference filters and sub-demultiplexers create little additional loss. As a result, the total power loss associated with the present invention is significantly less than that obtained with a conventional n channel demultiplexer based on a 1×n splitter. Accordingly, large numbers of channels, e.g., in excess of forty can be readily demultiplexed and detected.
摘要翻译：根据本发明，要解复用的光信道经由光分路器被提供给第一和第二光纤。耦合到第一和第二光纤的低损耗干扰滤波器选择相应的信道组。接下来，将各组信道用子解复用器分离成单个信道，然后用相应的光电检测器检测每个信道。虽然光分路器在多路分解器的输入端引入光功率损耗，但是干扰滤波器和子解复用器几乎不产生额外的损耗。结果，与本发明相关联的总功率损耗明显小于基于1xn分路器的常规n信道解复用器获得的总功率损耗。因此，可以容易地解复用和检测大量的信道，例如超过40个信道。

摘要： An optical add/drop multiplexer (OADM) is provided wherein input optical channels are supplied on first and second optical fibers, e.g. via an optical splitter. Low loss interference filters, for example, coupled to the first and second optical fibers, select respective groups or bands of channels. Selected groups of channels to be dropped by the OADM may be demultiplexed with sub-demultiplexers into individual channels. Groups of express channels are supplied to associated filters or gratings to ensure that the channel groups selected from the first and second optical fibers to do not contain undesired channels. Channels to be added by the OADM are multiplexed with sub-multiplexers into channel groups corresponding to the dropped channel groups. The added channel groups and the express channel groups are combined on a single output fiber.

摘要： An optical waveguide having a refractive index variation is formed by interfering two beams thereon and varying a fringe contrast of the interference pattern. This variation in fringe contrast may be provided by controlling the relative polarizations of the two interfering beams or the relative intensities of the two interfering beams. Preferably, a substantially constant total intensity is provided to the waveguide during the variation in fringe contrast.

摘要： A method, optical module, and optical amplifier are configured to detect fiber discontinuities at or near a port from which high powered optical signals are input into a fiber span. These fiber discontinuities can include fiber pinches, and are detected by monitoring for slight changes in a backscatter signal. Detection is quick and efficient based on the backscatter signal being attenuated by the fiber discontinuities twice, namely once as the high powered optical signals and again as the associated backscatter signal of the high powered optical signals returning to the port. Various remedial actions can be taken upon detecting fiber pinches at or near the port.

摘要： Raman amplifier systems and methods with an integrated Optical Time Domain Reflectometer (OTDR) for integrated testing functionality include an amplifier system, an OTDR and telemetry subsystem, and a method of operation. The OTDR and telemetry subsystem is configured to operate in an OTDR mode when coupled to a line in port and to operate in a telemetry mode when coupled to a line out port. The OTDR and telemetry subsystem enables on-demand fiber testing while also operating as a telemetry channel that is both a redundant optical service channel (OSC) and provides a mechanism to monitor Raman gain over time. The OTDR and telemetry subsystem minimizes cost and space by sharing major optical and electrical components between the integrated OTDR and other functions on the Raman amplifier.

摘要： The present disclosure provides reconfigurable optical add drop multiplexer (ROADM) node automatic topology discovery systems and methods providing a mapping of optical connections within a mesh optical network that includes tunable lasers and multi-degree ROADM's with colorless/directionless add/drop. The present disclosure may include additional transceiver, receiver, and add/drop filter equipment integrated in or disposed at a ROADM degree. This equipment supports a so-called topology wavelength which is one of a plurality of wavelengths supported by a wavelength division multiplexed (WDM) system that is dedicated and used solely for topology discovery. The topology wavelength may be utilized by the system to detect interconnects between ROADM degrees and between XCVRs/CDMDs. Further, the automated topology discovery may be integrated within a management system and/or control plane.
