1. Recovery of Fiber Drop Cable disconnection and Maintenance Solution 1) Disconnection of Fiber Drop Cables frequently happens worldwide due to environmental factors or man-made calamities. > SOLMate solution fusion splices the cable without any loss, and protects the cable with 100N tensile force. There is also no waste of cable. 2) Conventional solution using adapter with pre-connectorized cable for extension is costly and leads to a lot of losses. > SOLMate solution cleaves and fusion splices the cable without any loss during long distance communication 2. Fusion Splice Solution for Fiber Drop Cable Connector 1) Possible to replace the faulty connector only without replacing whole cable 2) Possible to utilize the idle cable by extension and connection of connector 3) Work as mini closure when FDF cannot be placed due to spatial problem

Actran TM A powerful acoustic CAE tool for turbomachinery noise prediction Actran TM is the reference CAE tool for analyzing the sound radiated by turbo machines and for optimizing the related acoustic treatments. Actran TM is used extensively by many leading aerospace companies that rely on the tools’ accuracy, ease-of-use and performance for reaching their strategic acoustic design goals. Actran TM contains all advanced modeling features required for turbo machinery noise analysis. To capture the important convection and refraction effects, the sound waves propagate on top of a non-uniform background mean flow which can be calculated by Actran or imported from a CFD simulation. The influence of the mean flow on the performance of acoustic liners is accounted for thanks to the Myers boundary condition. The acoustic source is defined in terms of incident duct modes of arbitrary order and their amplitude can be defined in a variety of ways (e.g. normalized amplitude, intensity, equal distribution of energy on all propagating modes) or derived from pressure fluctuations calculated on a set of planes by one of the supported CFD tools. Both 3D and axisymmetric models can be defined. One of the challenges of acoustic CAE is to handle large models associated to high wave number and to large geometrical size and complexity. Actran TM meets this challenge thanks to its efficient solver technology that includes advanced parallel processing. Actran TM is used not only for optimal aircraft engine nacelle liner design but also on inlet and outlet liners for helicopter turbines, environmental control systems (ECS) or auxiliary power unit (APU). Actran TM is also used for non aerospace applications like computer cooling system noise and more. Actran TM can be complemented by Actran DGM to solve problems involving complex shear layers and flow gradients occurring at the engine exhaust.
