Passive optical networks are being deployed worldwide to more cost-effectively deliver higher bandwidth broadband services to subscribers. FTTx PONs present technicians with unique installation verification and maintenance troubleshooting challenges. These challenges are effectively overcome when technicians understand FTTx PON architecture and are equipped with test tools designed to address the unique test requirements of FTTx PONs.
FTTH passive optical networks (PONs) are increasingly being deployed to provide optical fiber’s bandwidth advantages at a lower costthan point-to-point architecture affords. However, PONs present unique test challenges when installing and maintaining an FTTH network. This white paper provides an overview of FTTx PON architectures, identifies test challenges unique to FTTx PONs, and describes optical tests recommended to verify or troubleshoot FTTx PONs, including in-service (live) PONs.
