Abstract: A network node (3, 4) comprising at least one client interface port (40) and a database (46, 48) storing data allowing to retrieve for a given client interface, a service associated therewith, for a given service, a client interface associated therewith. A Maintenance End Point (MEP) (50, 52) is established on the network node and is associated with an end-to-end service between a client device (10, 12) connected with said client interface port and a remote client device connected to a remote network node (3, 4). Said MEP is configured to exchange connectivity messages with a corresponding MEP (50, 52) established on said remote network node and to detect a client interface fault and a service fault based on connectivity messages received from said corresponding MEP, or based on missing connectivity messages from said corresponding MEP. Said network node is configured to determine which service(s) is (are) related to said client interface and to inform the MEP related to this service about said client interface fault, and is configured to determine which client interface(s) is (are) associated with said service and to carry out a predetermined action associated with said client interface(s).

Abstract: A method of determining contributions of different sources of signal degradation for optical signals transmitted over an optical link in an optical transmission system, comprising measuring a performance value (P) of a signal transmission on said optical link, deriving, from the performance value, an auxiliary noise power value (PN) based on a predetermined relationship between the performance value (P) and the auxiliary noise power value (PN), wherein the auxiliary noise power value (PN) comprises contributions of amplified spontaneous emission power (PA) generated on the optical link and a link-related equivalent noise power contributions (PL) representing other sources of signal degradation upon transmission on the optical link, measuring or deriving an OSNR-related value (Q) for the signal transmission on the optical link, wherein the OSNR-related value (Q) corresponds to or is at least indicative of an actual OSNR on the optical link, and distinguishing, based on the auxiliary noise power value (PN) and on the OSNR-related value (Q) between noise power contributions of amplified spontaneous emission and link-related equivalent noise power contributions.

Abstract: The disclosed receptacle and method of the present invention enables light, such as port status/operation indicator light for example, to pass through at least a portion of the receptacle, and in turn illuminate at least a portion of the receptacle. In one example application or embodiment the light that so illuminates the receptacle originates from a light source that is external to the receptacle, while in another example application or embodiment the light originates from a light source within the receptacle.

Abstract: Disclosed herein is a transponder (14), comprising a transmitter (18) for generating and transmitting an optical signal and a receiver (20), wherein said receiver (20) comprises a receiver input amplifier (40) at the receiver's input. The transponder further comprises a bypass line (46) configured to selectively feed an optical signal from said transmitter (18) to the receiver (20), and a control unit (22) configured for determining the performance of the transponder (14) in relation to an OSNR related parameter, by controlling the transponder to generate a noise signal to be received by the receiver (20), by operating the receiver input amplifier (40) to thereby cause ASE in the receiver input amplifier (40) and to determine a noise intensity value, generate a test signal at the transmitter (18) and to determine a signal intensity value and superimpose said noise signal and said test signal, or replicas thereof, to form a combined signal to be received by said receiver (20) and determining said performance related parameter based on said combined signal, wherein for generating said combined signal, said test signal is fed from the transmitter (18) to the receiver by means of said bypass line (46).

Abstract: The proposed invention is in the area of managing resources in optical transport networks, for example in the area of in-operation media channel format and spectrum management. For this purpose, the type of Media Channel Format is determined for each of a plurality of candidate paths, wherein each candidate path connects a pair of nodes in an optical transport network. Then, the expected weight describing traffic volume of each of the candidate paths is determined, and a spectrum share is assigned to each link of each of the candidate paths based on the determined Media Channel Formats and determined weights. In this way, spectrum shares assigned to different links and candidate paths can be used for efficiently assigning a band spectrum to each of the Media Channel Formats of the candidate paths.

Abstract: A set of media channel (MCh) widths are determined to be used in an optical network. Based on the topology of the network, a first set of MCh widths are computed for tentative use in said optical network, said first set of MCh width defining a target spectral efficiency. A reduced set of MCh widths are generated from said first set of MCh widths by mapping each of the original MCh widths of said first set to a corresponding new MCh width, which is identical with or larger than the original MCh width. An optimization algorithm is used that penalizes MCh widths that are more likely to cause fragmentation problems in the spectrum, and penalizes a decrease in spectral width due to the mapping of an original MCh width of said first set to a new, larger width.
