# Fiber Switches - Published: 2025-07-01 - Updated: 2026-03-11 - Author: aktd-content - Source: https://precisioneersgroup.com/fiber-switches/ --- # Fiber Switches ![fiber switches 1 x 2 up to 1 x 9](https://precisioneersgroup.com/wp-content/uploads/2025/11/Fiber-Switch-471x259-1.webp) Fiber switches driven by piezos offer very low light loss and low power consumption - and are very fast. The small size of the switchbox and the easy control make these fiber optic switches ideally suited for use as a component of a spectrometer system or other metrology device. Fiber switches designed this way with no lenses or prisms have no wavelength dependent limitations. These precision piezo-driven switches guarantee a light transmission of >80%, with a typical switching time of <1 ms. Models are available that offer up to 9 inputs/outputs. Humidity resistant models are also available. Users can save time and cost while guaranteeing the best light quality. ## Fiber Switches can Reduce Overall equipment costs by eliminating multiple spectrometers Optical fiber switches can receive up to nine input signals and send output to a single spectrometer. The cost of a single fiber switch is considerably less expensive than the cost of multiple spectrometers. This will reduce your start-up costs and increase your ROI. ![spectrometer with a fiber switch saves equipment costs](https://precisioneersgroup.com/wp-content/uploads/2025/11/FiberSwitch-Savings-1-768x372.webp) ![cost savings using fiber switches](https://precisioneersgroup.com/wp-content/uploads/2025/11/FiberSwitch-Savings-2.webp) ## Fibers Switches Featured Models: ![PSJ small fiber switch 1 x 2](https://precisioneersgroup.com/wp-content/uploads/2025/07/PSJ-small-fiber-switch-1-x-2.jpeg) **1 x 2, Small Fiber Switches** Features: - For fiber core diameter sizes: 50 to 600 µm - Fast switching time - High optical isolation - Low insertion loss This small 2-channel (input or output) fiber switch is ideal for use with two inputs and outputting to a single source - such as using a single spectrometer. Other common uses include optical measurement systems, telecommunications and environmental trace analysis. | Sub-set of Models and Data | UNIT | Fiber Diameter 200 µm | Fiber Diameter 600 µm | | --- | --- | --- | --- | | [Insertion Loss (Typical)](https://royal-elementor-addons.com/) | [dB](https://royal-elementor-addons.com/) | [1.0](https://royal-elementor-addons.com/) | [0.8](https://royal-elementor-addons.com/) | | [Cross Talk (Typical)](https://royal-elementor-addons.com/) | [dB](https://royal-elementor-addons.com/) | [-60](https://royal-elementor-addons.com/) | [-50](https://royal-elementor-addons.com/) | | [Switching Time](https://royal-elementor-addons.com/) | [ms](https://royal-elementor-addons.com/) | [2](https://royal-elementor-addons.com/) | [7](https://royal-elementor-addons.com/) | | [Lifetime](https://royal-elementor-addons.com/) | [Cycles](https://royal-elementor-addons.com/) | [10⁹](https://royal-elementor-addons.com/) | [10⁹](https://royal-elementor-addons.com/) | | [Housing Size](https://royal-elementor-addons.com/) | [mm](https://royal-elementor-addons.com/) | [Approx. 175 x 135 x 45](https://royal-elementor-addons.com/) | [Approx. 225 x 195 x 45](https://royal-elementor-addons.com/) | [Request full Datasheet for 1 x 2 Small Fiber Switch](#contact) ![PSJ Medium Fiber switch 1 x 3 to 9](https://precisioneersgroup.com/wp-content/uploads/2025/07/PSJ-Medium-Fiber-switch-1-x-3-to-9.jpeg) **1 x 3 to 1 x 9, Medium Fiber Switches** Features: - For fiber core diameter sizes: 50 & 200 µm - Fast switching time - High optical isolation - Low insertion loss This 3 to 9 channel fiber switch is ideal for use with up to 9 inputs and outputting to a single source - such as using a single spectrometer.
