  • Patent number: 10097905
    Abstract: An XYX cross-connect switching matrix (200) is provided for use in telecommunications apparatus. The matrix (200) comprises first (10), second (20) and third (30) arrays of parallel conductor tracks (11-14, 21-28, 15-18). The parallel conductor tracks (21-28) of the second array (20) are oriented perpendicular to the conductor tracks (11-14) of the first array (10) and to the conductor tracks (15-18) of the third array (30). The first (10), second (20) and third arrays (30) each lie in planes parallel to and spaced from one another, with the second array (20) being located between the first (10) and third (30) arrays. A first set of electrical contact sleds (41) is provided between the first (10) and second (20) arrays, while a second set of electrical contact sleds (42) is provided between the second (20) and third (30) arrays. These sleds (41,42) enable any X conductor track (11-18) in the first (10) or third (30) array to be electrically connected to any Y conductor track (21-28) in the second array (20).

  • Patent number: 9671570
    Abstract: An optical wavelength division multiplexor module (40) has a housing (44) having a front face (45) and a rear face (46). The wavelength division multiplexor module (40) comprises a short wavelength path terminal (41), a common optical terminal (42), and a long wavelength path terminal (43). The short wavelength path terminal (41) comprises a first fiber optic adapter (48), for engaging a fiber optic connector of a first patch cable (24), while the common optical terminal (42) comprises a second fiber optic adapter (48), for engaging a fiber optic connector of a second patch cable (26). The long wavelength path terminal (43) comprises a fiber optic connector (49) for directly engaging with a fiber optic adapter (48) carried on a modified optical test access switch (50). The short wavelength path terminal (41) and the common optical terminal (42) are both provided on the front face (45) of the housing (44), while the long wavelength path terminal (43) is provided on the rear face (46) of the housing (44).
