Passive Optical Networks WDM PON Modules For GPON XGS-PON NG-PON2 OTDR
Description
Passive optical networks (PON) are the most attractive and extensively studied solutions for optical access technologies. Legacy GPON and EPON built with power splitter technologies are currently deployed as high-speed and high-capacity optical access technologies using time division multiplexing (TDM). All signals are distributed through this optical network from the optical line terminal (OLT) to every end user’s optical network termination unit (ONT) connected on the same PON branch.
The next-generation NG-PON should satisfy demands for increasing traffic and higher bandwidths. All future strategies for NG-PON evolution are expected to deploy WDM. The candidate systems are based on evolutionary growth. Current GPON systems are intended to migrate to NG-PON applying identical colorless ONTs. The migration would occur in the same optical distribution network which implies coexistence. The advantage appears in cost saving, easier planning, maintaining and expanding of this network. The evolutionary growth under NG-PON is based on the demand of the minimal equipment investments. NG-PON should operate with the same infrastructure as GPON. However, coexistence should be supported by some preventative measures to avoid interferences between downstream and upstream channels of GPON and NG-PON. Therefore, current GPON and NG-PON coexistence requires wavelength separation of signals assigned for ONTs of GPON, 10 Gbit PON (called: XG-PON) and WDM-PON. Low-cost WDM are required for the wavelength band separation to ensure that GPON ONTs can operate undisturbed alongside NG-PON deployments. Thin-film passive filters (TFF) are suitable low-cost, ONT-independent (i.e. coexisting) and simple operation candidates.
