Packet Transport

Optical transport is gradually shifting from the SONET/SDH standard to packet-centric solutions --- a move that requires operators to replace legacy MSTP. To help operators make the transition smoothly and successfully, NEC has released the new MN5000 Series.

This family of T-MPLS-based packet optical transport solutions enables packet-centric transport with TDM-like OAM operation.
