Abstract
Optical interconnection methods for high-speed data-rate optical transport systems are disclosed that optically interconnect active assemblies to a fiber optic cable in a polarization-preserving manner. The methods include defining active-assembly-wise connector ports that connect to active assembly transmit and receive ports, and defining or establishing a pairings method between the active-assembly-wise connector ports. In a first optical interconnection assembly, an active-assembly-wise port is optically connected to a cable-wise port. In the second optical interconnection assembly, the cable-wise port that corresponds to the connected cable-wise port in the first optical interconnection assembly is optically connected to a select active-assembly-wise port as defined by the pairings method. The optical connection process is then repeated from the second to the first optical interconnection assembly. The optical interconnection acts are repeated until all of the active-assembly-wise ports are connected.
