2.1 A bidirectional transceiver arrangement is specified which can be implemented in a more compact manner compared to a bidirectional transceiver arrangement which has already been proposed and which has two optical lenses and a separate wavelength-selective filter. 2.2 For this purpose, the bidirectional transceiver arrangement has, instead of the two lenses and the separate filter, a single plane-convex lens (3) on whose plane lens surface (31) the wavelength-selective filter (5) is arranged in the shape of a dielectric multilayer, which filter does not transmit the first wavelength ( lambda 1) emitted by the transmitter (1) and does transmit the second wavelength ( lambda 2) received by the receiver (2). 2.3 Use in customer access networks. <IMAGE> |
