This invention "SONET Like Link and Chassis Interconnect" serves to: (a) transmit and receive data between telecommunication chassis or circuit boards, using a simplified SONET format; and (b) interconnect a plurality of telecommunication chassis of routers or switches (cross-connects), to function as a scalable large router and or switch, with as many number of line interface ports and as much data rate. This system could start as a small investment, low data rate system, for example, a few hundred Gbps, and grow to a large investment high data rate system, for example 1 Pbps, by stacking many of them incrementally. This is accomplished by WDM and in a special case by non-WDM fiber optic technology, in a specific proprietary manner. This patent applies to routers and switches with Line Cards having electronic switching fabric(s) and Network Processor Unit(s) (NPU). The interconnection schemes suggested below is non-blocking, and takes from one to a certain maximum number of hops, to reach any Line Interface node from any other.
