Overview
The EMCORE DSP-3400 fiber optic gyroscope (FOG) offers the reliability and robust design found in all members of the DSP-3000 series, but adds the benefits of a true RS-422 interface and a 1000 Hz synchronous output in a durable, shielded package. As a result, the DSP-3400, with its robust, modular design, is a powerful option for use in applications requiring FOG output to be transmitted over a longer distance.
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, turnon to turn-on repeatability, and maximum input rate. Exceptional low noise (ARW), insensitivity to cross-axis error, and shock and vibration robustness make the DSP3000 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-3400 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 tacticalgrade inertial measurement systems.
The noise spectrum of the DSP-3400 is exceptionally flat, lacking the discrete noise components of mechanical gyros. With no moving parts to maintain or replace, the DSP-3400 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
