| 摘要 |
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 fibre optic adapter (48), for engaging a fibre optic connector of a first patch cable (24), whilst the common optical terminal (42) comprises a second fibre optic adapter (48), for engaging a fibre optic connector of a second patch cable (26). The long wavelength path terminal (43) comprises a fibre optic connector (49) for directly engaging with a fibre 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), whilst the long wavelength path terminal (43) is provided on the rear face (46) of the housing (44). |
