Description
1550nm In Line Depolarizer
1550nm In Line Depolarizer is built with quarter-wave plate which can be used for transfering the line polarization light into circularly polarized light or elliptically polarized light light to reduce the influence of the polarization state on the fiber system, it’s widely used in Quantum Communication, Fiber Optic Sensor and OCT field. High power type is also available upon request.
