Passive optical network (PON) systems are vulnerable to a variety of failures, including fiber
cuts and optical network unit (ONU) transmitter/receiver failures. Any service interruption …

Fiber to the Home (FTTH) is broadly acknowledged as the optimal solution for meeting the
current and future broadband requirements. FTTH involves the installation of optical fiber …

This paper introduces an in-service line monitoring technique that can locate a fault in
branched optical fibers in passive optical networks (PONs) from a central office. This …

We investigate experimentally and via simulation, the monitoring of fiber link quality in a
PON using optical coding technology. We discuss design issues for periodic coding and the …

As the ink is drying on 5G New Radio standards, the industry is now setting its sight on
specifying the transport network layer to support 5G deployments. Among the contending …

Individual users and enterprises are increasingly relying on the access to internet services
and cannot accept long interruption time as easily as before. Moreover, the main …

This paper proposes and experimentally demonstrates an automatic-protection-switching
(APS) mechanism against distribution fiber breaks in passive optical networks (PONs). The …

Feature Issue on Optical Code Division Multiple Access We propose, to the best of our
knowledge, a novel in-service live fiber-to-the-home (FTTH) passive optical networks …
