Function of 3x3 Fiber Optic Coupler

Performance of 3 X 3 couplers in fiber optic sensor systems

The performance of fiber optic interferometers constructed with 3x3 couplers is investigated. Deviations from ideal behavior are noted at low fringe visibilities.

AC Photonics Inc

Splitters and couplers divide optical inputs into multiple outputs, or combine multiple inputs into one or more outputs. ACP offers a wide variety of splitters/couplers, such as our 1x4 Singlemode Single

optics

These couplers were designed for power splitting or combining of optical signals. They are widely used for optical modules and the fiber sensors, fiber testing instruments.

3x3_Coupler_V1_0603

These couplers are fabricated by fusing 3 fibers together to couple power input from any one fiber equally between the three output fibers. The fused, monolithic configuration provides optimum loss

1310nm 3×3 Fused PM Fiber Splitter

It features low excess loss, small size and high polarization extinction ratio. 3×3 monolithic fused PM fiber standard splitter is widely used for optical sensors and optical gyro.
