    filed in Accordance with Article 97 No. 5 EPC
    and Rule 51 No. 6 of the Implementing Regulations
    1. Einfüge- und Abnahmemuitiplexer für die Abnahme von wenigstens einem optischen Träger, der durch ein Informationssignal moduliert ist, aus einem Fluß optischer Signale, der eine Mehrzahl von Trägern unterschiedlicher Wellenlänge umfaßt, und für die Wiedereinfügung des selben, durch ein anderes Informationssignal modulierten Trägers in den Datenfluß, mit zwei nominell identischen Interferenzfiltern (11, 12), von denen einer die Abnahmefunktion und der andere die Einsetzfunktion ausübt, dadurch gekennzeichnet, daß die beiden Filter (11, 12) in parallelen Ebenen angeordnet und an gegenüberliegenden Flächen eines transparenten Körpers (13; 103) so befestigt sind, daß der Datenfluß den Multiplexer {10; 100) verläßt, nachdem er von beiden Filtern reflektiert worden ist, und daß der transparente Körper (13; 103) auf einem Träger (14) montiert ist, der an einer Achse scharnierartig angelenkt ist, die durch den Massenmittelpunkt des Multiplexers (10; 100) und parallel zu den Ebenen der Filter verläuft, und ihnen Einrichtungen (16. 17) zugeordnet sind, die seine
    Verdrehung in beliebiger Drehrichtung zum Verändern der Abstimmwellenlänge der Filter bewirken.
  2. 2. Einfüge- und Abnahmemultiplexer gemäß Anspruch 1, dadurch gekennzeichnet, daß der transparente Körper eine transparente Platte (13) umfaßt, die die beiden Filter (II, 12) trägt.
  3. 3. Einfüge- und Abnahmemultipiexer nach Anspruch 1, dadurch gekennzeichnet, daß der transparente Körper (103) zwei Elemente (104, 105) umfaßt, vcn denen jedes eines der Filter (11, 12) trägt und die miteinander über eine Haibwellenplatte (106) verbunden sind, die Doppelbrechungsachsen bei 45° in Bezug zur Einfallsebene auf die Vo rrichtung (100) des die Mehrzahl von Trägern umfassenden Flusses aufweist und die der Fluß auf seinem Weg zwischen den beiden Filtern (11., 12) durchquert.
