We present the experimental demonstration of cascaded arrayed waveguide grating (AWG). Here we use the OLT (Optical Layer Termination) has 2 layer stacks. A tuneable one for unicast transmission and another one for multicast transmission. Downstream and upstream data share same optical path. BER curves were measured by using 2.5 GB per sec. data stream in each direction and error free transmission is achieved for downstream and upstream. For this proposed experimental setup is evaluated by using optic system software ver.12.
