International Classification:
H04B 10/08
US Classification:
398 14, 398 34, 398 33
Abstract:
Optical autodiscovery is provide between two optical modules to insure that when an optical signal is coupled between the two optical module, the optical signal from a first module does not interfere with operation of a second module. The autodiscovery is implemented by sending an optical identification signal from the first optical module via the coupling to the second optical module from which signal, the second optical module can verify and determined acceptance of the coupled first optical module. During this autodiscovery process, the optical identification signal from the first optical module may be attenuated or shifted in optical spectrum so as not to interfere with the operation of the second optical module. Autodiscovery may also be employed in cases where a first optical module is to receive an optical signal from a second module.

The signal outputs of the modulated sources optically coupled to inputs of the wavelength selective combiner to produce a combined signal output from the combiner. A first wavelength tuning element coupled to each of the modulated sources and a second wavelength tuning element coupled to the wavelength selective combiner. A wavelength monitoring unit is coupled to the wavelength selective combiner to sample the combined signal output. A wavelength control system coupled to the first and second wavelength tuning elements and to said wavelength monitoring unit to receive the sampled combined signal output.

Abstract:
A digital optical network (DON) is a new approach to low-cost, more compact optical transmitter modules and optical receiver modules for deployment in optical transport networks (OTNs). One important aspect of a digital optical network is the incorporation in these modules of transmitter photonic integrated circuit (TxPIC) chips and receiver photonic integrated circuit (TxPIC) chips in lieu of discrete modulated sources and detector sources with discrete multiplexers or demultiplexers.

International Classification:

US Classification:
398 94, 398 93, 398 38
Abstract:
A system, apparatus and method are described for deployment of a control loop between optical or electro-optical modules and a multiplexing module to provide a desired power profile of banded optical channel groups. The power output characteristics of the optical or electro-optical modules, the properties of the transmission paths of the banded optical channel groups, and other factors may be analyzed to allow the control loop to achieve the desired power profile on the banded optical channel groups. The control loop may adjust the output power on the optical or electro-optical modules so that the banded optical channel groups are delivered to an optical component, such as an optical multiplexer or photo-detector, having a particular optical power profile.

International Classification:
H04B 10/00
US Classification:
398168
Abstract:
A system, apparatus and method are described for controlling the gain across one or more amplifier nodes within an optical span. In one embodiment, a fast local amplifier constant gain control loop is provided that maintains a constant gain across an amplifier node for each of the channels within an optical signal. A slow link level gain setting control loop is provided to set and/or adjust the target gain on the amplifier node(s). A gain adjust sequence is performed by the slow link level gain setting control loop to adjust the target gain(s) in response to various events and mechanisms. A “time of flight” protection method is also provided to ensure consistency between the fast local amplifier gain control loop and the slow link level gain setting control loop.
