Passive Optical Network introduction

Defination Passive optical network-PON is a network that brings optical fiber singal to the end of users by the point-to-multipoint(P2MP) fiber to the premises in which optical splitters are used to “broadcast” signals to many users. A PON consists of an optical line terminal (OLT) at the service provider’s central [ Continue reading…]
