Mode Multiplexer FSM4APC-O&CL
Mode multiplexers convert modes and multiplex/demultiplex signals for combination or separation. The process is reversible: separate modes combine into few-mode fiber, or superimposed modes separate into single-mode fibers. O and C+L band operation supports parallel multichannel transmission over one fiber, exponentially increasing communication capacity for space-division-multiplexed systems, sensing, and network equipment. Standard products include 2-mode and 4-mode multiplexers with LC/APC interfaces. The 2-mode version supports 2 modes (LP01, LP11); the 4-mode version supports 4 modes (LP01, LP11a, LP11b, LP21b). 2-mode multiplexer. Model: FSM2APC-CL. Compact package. LC/APC interface. 2 multiplexed modes: LP01, LP11. Band: C+L. The 2-mode multiplexer supports C+L, converting 2 inputs into 2 multiplexed few-mode modes (LP01, LP11). Compact LC/APC packaging is small and easy to use. Typical insertion loss: 0.5 dB; typical mode extinction ratio: 20 dB. 4-mode multiplexer. Model: FSM4APC-O&CL. Compact package. LC/APC interface. 4 modes: LP01, LP11a, LP11b, LP21b. Bands: O and C+L. The 4-mode multiplexer supports O and C+L, converting 4 inputs into 4 multiplexed few-mode modes (LP01, LP11a, LP11b, LP21b). Compact LC/APC packaging is small and easy to use. Insertion loss: 4.5 dB typical, 6 dB maximum. Typical mode extinction ratio: 20 dB.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
