Overview
The EMCORE DSP-3100 fiber optic gyroscope (FOG) is designed for demanding applications requiring high-speed data output, and offers a powerful high-speed RS-422 interface with 1000 Hz asynchronous in a package more compact than the EMCORE DSP-3400. With its industry-standard Samtec 26-pin connector, it offers a versatile package ideal for installations with tighter installation requirements while not sacrificing performance, reliability, or durability.
EMCORE’s breakthrough DSP design overcomes the limitations of analog signal processing, virtually eliminating temperature-sensitive drift and rotation errors. In addition, EMCORE’s DSP technology offers significant performance improvements in such critical areas as scale factor and bias stability, scale factor linearity, turn-on to turn-on repeatability, and maximum input rate. Exceptional low noise (ARW), insensitivity to cross-axis error, and shock and vibration robustness make the DSP-3000 series a perfect fit for demanding industrial applications. This performance, combined with the inherent simplicity and reliability of our mature all-fiber optical circuit, establish the DSP-3000 series as an affordable, outstanding solution for motion sensing, stabilization, navigation, and precision pointing applications.
Fabricated from EMCORE’s proprietary E-Core® polarization maintaining fiber, the EMCORE DSP-3100 delivers superior precision and reliable performance at a lower cost than other comparable fiber optic and mechanical gyroscopes. Its temperature stability and repeatability make it particularly well-suited for precision stabilization, GPS integration, and multi-axis tactical-grade inertial measurement systems.
The noise spectrum of the DSP-3100 is exceptionally flat, lacking the discrete noise components of mechanical gyros. With no
moving parts to maintain or replace, the DSP-3100 lasts longer, functions better, and yields significant product life cycle savings.

Available Configurations
The DSP-3000 series comes in three variations:
- If you require a compact FOG with a choice of analog, digital, and digital RS-232 outputs, consider the DSP-3000 FOG.
- If you need a compact FOG with a powerful high-speed RS-422 interface with 1000 Hz asynchronous output, consider the DSP-3100 FOG.
- If you require a true RS-422 interface and a 1000 Hz synchronous output in a durable, shielded package, take a look at the DSP-3400 FOG
