Summary: 
Triggered by the Great East Japan Earthquake in March 2011, the authors have been studying a resilient network whose key element is a movable and deployable ICT resource unit. The resilient network needs a function of robust and immediate connection to a wide area network active outside the damaged area. This paper proposes an application of digital coherent technology for establishing optical interconnection between the movable ICT resource unit and existing network nodes through a photonic network, rapidly, easily and with the minimum in manual work. We develop a prototype of a 100Gbit/s digital coherent transponder which is installable to our movable and deployable ICT resource unit and experimentally confirm the robust and immediate connection by virtue of the plug and play function.
