Transparent, all-optical interconnection of two independent experimental OFDM-LANs via one central node

The all-optical transparent interconnection of two experimental OFDM-LANs is demonstrated. Fiber amplifiers are used to compensate network losses. Each LAN is equipped with four fully engineered, microprocessor-controlled, absolute frequency stabilized subscriber stations. The interconnection is realized utilizing a full duplex star coupler as central node. A proposal to extend the realized network for frequency re-use is given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
