Abstract: A method, system, and computer-readable medium for a network interface with adjustable rate are disclosed. For example, one method involves receiving a request to activate a virtual lane of an interface, where the request is received by a first node. The interface is configured to facilitate data communication between the first node and a second nod, and the interface includes a plurality of virtual lanes that include at least one active virtual lane, and at least one inactive virtual lane. The method also involves, in response to receiving the request, negotiating with the second node to select an additional virtual lane from the at least one inactive virtual lane. The method involves activating the additional virtual lane. After the activating, the first node and the second node are configured to use the active virtual lane(s) and the additional virtual lane for data communication.

Abstract: An interface mapping method includes obtaining, at a network controller, device information of network devices configured to be in communication with each other through an optical network. The network devices include a plurality of colored interfaces that support a range of wavelengths for communication in the optical network. Interface information of the colored interfaces of the network devices is obtained, and optical power information associated with each of the colored interfaces is obtained. Optical power margins for a transmitter interface of the colored interfaces. The transmitter interface is controlled to transmit a power sequence based on the optical power margins, and power readings are obtained from a receiver interface of the colored interfaces. A topology between the colored interfaces is discovered based on the power sequence and the power readings.

Abstract: An optical amplifier may comprise a first gain stage and a second gain stage. Each of the first and second gain stages may comprise a laser pump and an active fiber. A liquid crystal device may be coupled between an output of the first gain stage and an input of the second gain stage. A control unit may be coupled to the first and second gain stages, liquid crystal device and configured to control the first and second gain stages, and the liquid crystal device to provide a switchable gain. Light may pass through the first and second gain stages and be amplified by the first and second gain stages. The light amplified by the first gain stage may pass through the liquid crystal device and may be filtered by the liquid crystal device.
