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 …

While the concept of Software Defined Networking (SDN) has seen a rapid deployment
within the data center community, its adoption in telecommunications network has …

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 …

Hybrid passive optical converged access networks (HPCANs) are recognized as a cost-
efficient and high-bandwidth solution to address the exponentially increasing demands of …

Optical sensing that integrates communication and sensing functions is playing a more and
more important role in both military and civil applications. Incorporating optical sensing and …

Survivability has already been an important research focus for the terrestrial optical network
(TON). Various survivability technologies such as the pre-configured structure scheme, the …

1+ 1 protection is a method to secure traffic between two nodes against failures in between.
The sending node duplicates the traffic and forwards it over two disjoint paths. The receiving …

The elastic lambda aggregation network (EλAN) has been presented as an
access/aggregation integrated network that can accommodate multiple network services. In …

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 …
