N2 - Multicore fiber (MCF) transmission is considered as one of the promising
technologies for breaking the capacity limit of traditional single mode
fibers (SMFs). Managing the XT and configuring optical paths adaptively
based on the XT are important as well as achieving longer-distance and
larger-capacity transmission, because inter-core crosstalk (XT) could be
the main limiting factor for MCF transmission. In a real MCF network,
the inter-core XT in a particular core is likely to change continuously
as the optical paths in the adjacent cores are dynamically assigned to
match the dynamic nature of the data traffic. If we configure the
optical paths while ignoring the inter-core XT value, the Q-factors may
become excessive. Therefore, monitoring the inter-core XT value
continuously and configuring optical path parameters adaptively and
flexibly are essential. To address these challenges, we develop an MCF
transport network testbed and demonstrate an XT-aware traffic
engineering scenario. With the help of a software-defined network (SDN)
controller, the modulation format and optical path route are adaptively
changed based on the monitored XT values by using programmable devices
such as a real-time transponder and a reconfigurable optical add-drop
multiplexer (ROADM).
