Abstract: Optical amplifiers are typically disposed along the transmission path of an optical system. If a large number of optical amplifiers, e.g., eight, are so disposed, then it is likely that an appreciable level of so-called power divergence will occur among the optical signals forming a composite optical signal that traverses the path. Disadvantageously, when the composite signal is received at a destination and demultiplexed, a number of the demultiplexed optical signals will contain components of the other demultiplexed optical signals as a result of such power divergence. This problem is readily handled using a facility which greatly suppresses such components in a demultiplexed optical signal.

Abstract: An optical wavelength add/drop multiplexer (WADM) is configured to add or drop two or more signals each associated with one of a plurality of channels in a wavelength division multiplexed (WDM) signal. The WADM comprises an optical circulator that is optically coupled at one port to two or more serially interconnected fiber Bragg gratings (FBGs), and is optically coupled at another port to a thin film filter including two or more serially interconnected thin film filter elements. Each of the two or more FBGs is matched with a thin film filter element, both arranged to be responsive to signals associated with one of the plurality of channels. Bandwidth and dispersion properties for the FBGs are selected to permit operation of the WADM at two distinct signal data rates. To equalize associated insertion losses in embodiments of the invention arranged to add or drop two or more signals, the FBGs are matched to the thin film filter elements in inverse order with respect to their optical distance from the optical circulator.

Abstract: A method and apparatus are disclosed for providing optical channel adding/dropping capability within a WDM filter-bypass device. The device comprises an optical filter, an optical switch, and means for receiving a control signal to configure the optical switch. When configured in a filter state, the switch routes the WDM signal through the filter to drop, add or drop and add one or more pre-selected WDM channels. When configured in a bypass state, the WDM signal bypasses the filter. A series of filter-bypass devices may be interconnected to increase the number of optical channels that can be dropped or added.

Abstract: A facility is provided to enhance the simultaneous transmission of optical signals of different data rates, for example, OC48 and OC192 signals.
Specifically, a first stream of channels carrying signals of different data rates and a second stream of channels carrying signals each having the same data rate are supplied to respective inputs of an asymmetric wavelength combiner, which interleaves the streams at an output for transmission over an optical path. Advantageously the combiner inherently reshapes the signals that it processes, which makes it ideally suited to offset cladding mode problems encountered when demultiplexing and multiplexing the signal streams.
