WDM-PON is known as a promising technology for future access network. This paper investigates the performance of a
novel 2.5Gbps WDM-PON Network architecture which employs new PON optical add/drop multiplexer (OADM), in
order to support high coverage in unlimited scaling. Based on the architecture, higher installation and maintenance costs
can be reduced, and the access network design can support symmetric transmission rate 10Gbps for distance up to 30 km
This paper introduces a novel FTTH-PON network architecture suitable for unlimited user and service scaling. It employs a passive NxN AWG and exploits the wavelength cyclical routing which is made possible by the devices Free Spectral Range (FSR) property at 2.5Gbps. The proposed architecture is based upon the WDM-PON features unique
properties including the possibility of offering simultaneously both broadcast and switches services plus additional advantages in term of signal privacy, easy fault location and direct capacity upgrade and also has the potential of offering a wide variety of services on the same physical network. Although the additional AWG in the network posses an extra 5dB power penalty but an optical transmission test demonstrate an error free transmission has been achieved with a 25km passive optical link with a 16×16 AWG and a 1×32 splitter installed.
