signals on fiber 112 are passed through a 1 u00d7 n wavelength division multiplexer 114 which separates the signals onto n different fibers in the embodiment shown there are n different dwdm pon signals on fiber 112 and each of these signals is broken out onto a separate fiber 116 1 n the gigabit pon signals on fiber 110 are passed to a splitter 120 which splits the signals into a corresponding number of optical fibers 122 1 n each carrying the common wavelength pair signals in the embodiment shown the splitter 120 is a 1 u00d7 n splitter corresponding to the 1 u00d7 n wavelength division multiplexer 114 each of optical fibers 116 1 n and 122 1 n are passed into separate wavelength division multiplexers 124 1 n of which only wdm 124 1 and 124 n are shown for simplicity which combine the common wavelength pair signals on the optical fibers 122 1 n with each individual and now separated unique wavelength pair signal on optical fibers 116 1 n to form subscriber lines 126 1 n which carry both the common wavelength pair signals and one of the sets of unique wavelength pair signals to a subscriber 104 e g 104 1 and analogously to other subscribers 104 2 n through use of the system 100 a subscriber 104 therefore receives the common wavelength signals and one of the pairs of unique wavelength signals allowing two different passive optical network services e g gigabit pon and dwdm pon to be delivered to the subscriber without requiring rewiring or additional wiring to the subscriber 39 s premises referring now to fig3 a schematic view of a system 200 for delivery.
