Three-axis FOG AF-3120

Turn-on Time: ≤5 s Dynamic Range: -300~+300 Bias Stability [1σ,100s]: ≤0.005 °/h

The three-axis closed-loop fiber optic gyroscope assembly is used to measure angular rates about three axes relative to inertial space.

Xuhai Optoelectronics uses innovative nano-optics to provide a free-space optical circulator within 2mmx2.5mmx3.5mm. Outgoing laser light couples through the circulator into a common fiber, while incoming light couples from that fiber to a photodetector. It fits standard BiDi BOSA housings without increasing the volume of existing single-fiber bidirectional modules. Low insertion loss (<0.5dB) and high isolation (>40dB) support same-wavelength single-fiber bidirectional transmission, OTDR and laser ranging. Its loopback functionality is particularly suitable for these applications. Traditional pigtail circulators or splitters have limitations: 1. Ordinary circulators are bulky and contain many components, making integration and assembly difficult. 2. Splitter alternatives have high insertion loss (6dB). 3. Finisar's extensive patent protection makes conventional optical designs difficult to implement without infringement. Xuhai's patented free-space circulator addresses these limitations and offers the following features.

Insertion loss ( Port 1->2) IL12: max:0.7 dB Insertion loss ( Port 2->3) IL23: max:0.75 dB Crosstalk ( Port 1->3) XT [@ IL12+IL23≤4.5dB]: min:40 dB

The Optoxuhai integrated free-space circulator uses distinctive nanomaterial technology to provide ultracompact size, excellent optical performance, and a simple optical structure. It offers stable performance, reliability, and good cost effectiveness.

The high-power isolator with collimated beam output is an isolator with fiber input and free-space output. An isolator is an optical device that allows light to travel in only one direction. It is most commonly used to prevent reflected light from entering a light source and is widely used in fiber lasers.

This assembly expands and spatially filters an incident collimated laser beam, significantly improving spot quality by removing higher-order spot components to produce a uniform, clean beam.
