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.
