An apparatus and method of operation of a multimode terminal on different network technologies. The method further includes encapsulating the circuit board in a casing by filling the cavity with a resin material so that the gap is filled with the resin material. The transmission path includes at least one repeater having an optical amplifier located therein. The structural layer includes a tongue and a flexure bond pad shelf. In accordance with the present invention, when the array has been composed, it is over-wrapped with a loop of thin, inexpensive, gas-permeable film applied under pressure or shrunk around the array, leaving two opposite faces of the array free of the over-wrapping loop.
