Low - Cost Optical Transceiver for PON Using Micro …
11 Fujikura Technical Review, 20071. Introduction Fiber-to-the-home (FTTH) system is becomingwidely used now. Passive Optical Network (PON)system will be commonly selected because of its cost-effectiveness. In the PON system, every subscriber isrequired to install an Optical Network Unit (ONU) athis/her home. Therefore, cost reduction of the ONUis essential. A major portion of the ONU cost comesfrom an Optical Transceiver , and, therefore, the costreduction of the Transceiver is most have developed a novel Transceiver and anOptical Sub-Assembly (OSA), the key element of atransceiver, for Gigabit Ethernet-PON1)(GE-PON),which operates at 1 Gbit/s data rate Using Ethernettechnology.
fore share an Optical Line Terminal (OLT) in the cen-tral office. Figure 2 shows the block diagram of a con-ventional GE-PON ONU transceiver. In this system,
