Estimating the term…
An array-type polarization-maintaining multi-core fiber includes a main outer cladding, fiber core units, and stress units. The fiber core units and the stress units are arranged to form a unit array including one central unit and any unit in the unit array being equidistantly arranged from adjacent units thereof. Provided is at least one pair of stress units, each pair of stress units being arranged symmetrical about one fiber core unit to form a polarization-maintaining fiber core unit. The fiber core units each include a fiber core and an inner cladding surrounding a core layer. A portion outside the fiber core units and the stress units is the main outer cladding. The fiber can greatly enhance spectral efficiency of an optical transmission system, and improve fiber communication capacity.
An array-type polarization-maintaining multi-core fiber, including a main outer cladding and fiber core units, and further including stress units, wherein the fiber core units and the stress units are arranged to form a unit array, the unit array including one central unit and any unit in the unit array being equidistantly arranged from adjacent units thereof;
