Fiber Tunable Coupler

Fiber Tunable Coupler

Configuration

Device holder: hole for screw to fix the device. ∅7(mm)

Strain relief: fiber pigtails in/out (basically 2 × 2 configuration)

Base dimension: 66×39×25 (mm)

Control knob : controls coupling ratio (0 - 100 %)

Operation

Coupling ratio:

- Coupling ratio is adjusted by using the control knob.

- Scales marked on the control knob do not represent the actual coupling ratio, but provide the reference. Relation between the scale and the actual coupling ratio can vary unit by unit, and is denoted in the data sheet.

- For the exactly reproducible coupling ratio at the same scale point

l   Adjust the coupling ratio from smaller to larger direction.

l   If the desired coupling ratio is smaller than the current condition, reset the knob to 0 and adjust to the desired point.

- Do not apply the excessive force on the control knob beyond the limit points.

- Coupling ratio can vary at different temperature.
