摘要： A reconfigurable multi-channel (WDM) optical ring network with optical shared protection. Preferably, the shared protection is based on a channel optical shared protection ring. The reconfigurable multi-channel (WDM) ring network connects signals between add/drop nodes with reconfigurable optical add/drop multiplexers (ROADM). The ring architecture is used to provide redundant paths between any transmitter and receiver so that failure on one side of the ring does not cut the service. The optical shared protection ring supports full redundancy. The shared protection supports wavelength reuse and availability of protection bandwidth for low-priority traffic. The shared protection implementation can also provide full equipment redundancy including transponders if desired. The ROADM components allow for reconfiguration of the multiplexer from a remote site and can be used in a network having both shared and dedicated protection.

摘要： A method of controlling an optical signal receiver utilizes three control loops: a first control loop tunes the decision threshold of the receiver when the optical network is in a substantially steady state and a second control loop rapidly switches to a reference decision threshold upon the occurrence of an alarm condition. The invention rapidly switches to a predetermined reference decision threshold to compensate for optical signal changes in eye Q and received power after a protection switch or traffic reroute. After a protection switch, a slower tuning algorithm is used to adjust the decision threshold to a more optimum value. In the third control loop, the optical signal receiver may utilize a peak detector that detects the optical signal peak and a potentiometer that is commanded by a controller to output a commanded percentage of this peak value to adjust the threshold and thereby respond to transients.

摘要： A novel wavelength measurement method wherein an optical pulse is launched into a dispersive medium with known dispersion properties, such as a dispersion compensating fibre or a dispersion compensating Bragg grating. The specific wavelength of the dispersion-induced light beam is obtained by measuring the propagation time delay through the dispersive medium and relating that propagation time to the calibrated dispersive medium.

摘要： This invention relates to provisioning wavelength-selective switches and reconfigurable optical add-drop multiplexers to minimize the bandwidth narrowing effect from the optical filters. Novel architectures and methods are disclosed that can significantly reduce bandwidth-narrowing on channels in a reconfigurable WDM network where a large number of optical filter elements are cascaded. Instead of blocking unused channels as in the prior art, unused channels are selectively provisioned depending on the state of their adjacent channels. Unused adjacent channels of an active channel are provisioned to follow the same path as the active channels. As each channels is deployed, the channel frequency is selected so as to minimize bandwidth narrowing.

摘要： A frequency dependent optical isolator is provided which allows two signals transmitted on a single optical fiber to be isolated in dependence upon their frequencies. A signal having a frequency f1 propagates through the isolator in one direction from a first input/output port to a second input/output port and is prevented from propagating in the reverse direction. A signal having a frequency f2 propagates through the isolator from the second input port to the first input port and is prevented from propagating in the reverse direction. After either of the signals propagates through the isolator from one input/output port to the other, the isolator prevents the respective signal from traveling backwards in a reverse direction through the isolator. The frequency dependent isolator may be used with an amplifier or may amplify one or more of the signals propagating through.

摘要： A method for optimizing an optical transmitter is provided. According to one exemplary method, the optical transmitter is optimized by varying three transmitter parameters including the bias voltage, the crossing level and the peak-to-peak voltage. Once the respective optimal levels for the bias voltage, the crossing level and the peak-to-peak voltage are obtained, the optical transmitter is further checked to ensure that the optical transmitter is able to function properly within certain predetermined system parameters. The optical transmitter is also checked under two limiting scenarios to ensure that the optical transmitter is optimized against two predetermined lengths of optical fiber.
