    Abstract: A system installed in a cross-border area between a provider network of a provider and a customer network of a customer includes: a smart optical network termination device (NT) at a site of the customer, wherein the smart optical NT is configured to implement a demarcation point between the customer network and the provider network, and wherein the smart optical NT is independent of a data rate passing through it and an optical interface connected to it; and a monitoring device located at a point of presence (PoP) of the provider network. The smart optical NT is further configured to monitor a coupling of optical power by the customer into the provider network and to interact with the monitoring device via at least one traffic analysis point (TAP) for connectivity validation from the PoP to the demarcation point.

    Abstract: Provided is an apparatus for determining the temperature of at least one fluid. The apparatus includes an optical fiber. A first end of the optical fiber is connected to at least one fiber tip, and a first additional reflector is introduced into the at least one fiber tip at a first predetermined distance from an outer end of the at least one fiber tip. A second end of the optical fiber is connected to a processing apparatus. The processing apparatus includes an optical source. The optical source is configured to launch an optical signal into the optical fiber, and a coherent detector. The coherent detector is configured to determine the temperature of at least one fluid by receiving a first light signal that corresponds to parts of the optical signal that are reflected at the outer end of the at least one fiber tip when the at least one fiber tip is inserted into the at least one fluid and a second light signal that corresponds to parts of the optical signal that are reflected at the first additional reflector when the at least one fiber tip is inserted into the at least one fluid, determining a difference of the optical phases of the first light signal and the second light signal, and determining the temperature of the at least one fluid based on the difference of the optical phases of the first light signal and the second light signal.
