About PHUJIN Project

The PHUJIN project (PHotonic network research project toward beyond the 5G era fully Utilizing space and wavelength dimensions by a Joint industry-academia-government INnovation driven team) seeks to scale the optical network capacity while decreasing the routing cost-per-bit and extending the optical reach by introducing spatial division multiplexing (SDM) technology using a spatial bypass through a spatial cross-connect that incorporates a core-based routing capability.

PHUJIN is a national project supported by the National Institute of Information and Communication Technology (NICT) in Japan (Grant no. 00201) that was started in August 2021 and will continue for four years.
