By Steve Harris – Today, most operators are on the path to a passive optical network (PON) deployment. Many operators are only focused on upstream and downstream bandwidth in their deployment of FTTH or migrating their old PON technologies to a new more robust PON solution. Migration is not easy, often laborious, and complicated, presenting service interruptions for subscribers.
