Seeking reduction of capital and operational costs on next-generation fiber networks is the
holy grail of network planning and deployment for all operators worldwide. In particular …

We demonstrate fast restoration of PON services with a dual-homed, shared-OLT protection
mechanism. Using the SDN-controlled pan-European GEANT core network, we demonstrate …

Design and experimental test of 1:1 end-to-end protection for LR-PON using an SDN multi-tier
control plane Page 1 ECOC 2014, Cannes - France Mo.3.2.4 Design and experimental test of …

The mass deployment of fiber access networks is probably the most important network
upgrade strategy for operators over the coming decade. Next-generation networks, and in …

Long-reach passive optical networks (LR-PONs) prove to be a suitable candidate for future
broadband access networks. The longer reach of the feeder fiber in a LR-PON enables us to …

Adaptability of high capacity passive optical network (PON) requires the provision of an
efficient fault detection and restoration mechanism throughout the network at an acceptable …

Protection strategies for long-reach PON Page 1 Protection Strategies Marco Ruffini (1) CTVR

Passive optical networks (PONs) have recently emerged to be a promising approach to
enhance the penetration of fiber towards the subscriber side, thus further enables delivery of …

A disaster-resistant, point-to-multipoint network configuration that connects distributed
optical terminals to a centralized optical terminal, through an exclusive fiber link, is required …

This paper presents a novel PON protection configuration using N: M protection. The
proposed configuration has several advantages including a flexible and scalable design …
