摘要： There is proposed a method and a module for real time control of power per optical channel in a multi-channel optical communication line formed by a group of optical elements connected in a chain by fiber spans. The group of elements comprises one or more optical fiber amplifiers (OFA); each of the spans is characterized by its span loss, while each of the OFA is characterized by its gain and its designed output power per channel. The method comprises steps of calculating an expected total input power value (EIP) for a particular optical amplifier (OFA) in the line, measuring a real total input power (MIP) at the particular optical amplifier, and comparing the values. If a difference between the EIP and the MIP at the OFA exceeds a predetermined value, the method (and the module) ensures adjusting the gain of the OFA to maintain its output power per channel constant.

摘要： A method of allocating a protection path in a communication network according to a maximum risk level allowed for affecting both main and protection paths by a single damaging event, is disclosed. The method is directed to ensure that for a required level of protection, derived from a maximum risk level allowed, no segments in the protection path, when taken together with any segment of the main path, presents a risk higher than the maximum risk level allowed.

摘要： A method is proposed for improving protection of data traffic in an optical ring network, where the data is arranged in SDH/SONET frames and the network supports a standardized MS-SPRING/BLSR protocol. The method comprises providing means to distinguish between a first kind and a second kind of coded protocol messages. The first kind of the messages is a bridge request message sent from node P (a first node) to node Q (a second node) and signaling about a unidirectional signal failure or degradation between the node P and Q, and the second kind of the messages is an acknowledgement message sent from node Q to node P in response to the bridge request message.

摘要： A hinge assembly, which permits convenient assembly and disassembly by simple push operations, includes a first part to be secured to a body member and carrying a hinge pin, and a second part to be secured to a pivotal member and carrying a socket for pivotally receiving the hinge pin of the first part. The hinge pin is retractably mounted to the first part so as to be movable to an extended, operative position receivable within the socket of the second part for pivotally mounting the pivotal member to the base member, and to a retracted, released position spaced from the socket of the second part for permitting removal of the pivotal member from the body member. Also described is a cabinet with at least one such hinge assembly on each of the two opposite edges of the main cabinet section and cover section, respectively. One hinge assembly serves as a pivotal mounting of the cover section to the main cabinet section permitting the cover section to be pivoted to its open and closed positions with respect to the main cabinet section; and the other hinge assembly serves as a releasable latch for latching the cover section in its closed position with respect to the main cabinet section.
