Ultra-low noise polarization diversity coherent reception module UPDR-2.5G-A

The ultra-low noise polarization diversity receiver module is designed for polarization-sensitive fiber optic sensing applications. This module coherently processes the two polarization states of the local oscillator and signal light separately, using two high-speed, low-noise balanced detectors for independent reception. It effectively solves the issue of coherent polarization states. This series is an upgrade of the original PDR series, significantly reducing the background noise, thereby providing higher signal-to-noise ratio for signal detection.

800nm conventional polarization-dependent free-space optical isolator A07 package

Free-space optical isolators can be divided into two types: polarization-dependent and polarization-independent. Polarization-dependent isolators, also known as Faraday isolators, consist of three parts: a polarizer, a Faraday rotator, and an analyzer (which is oriented at a 45° angle to the polarizer's axis).Polarization-independent isolators primarily consist of a birefringent crystal (or polarizer), a Faraday rotator, and a half-wave plate. These are commonly used in fiber lasers and are effective at maintaining the stability of optical systems. These isolators use high-quality magneto-optical crystals, offering low absorption, high extinction ratio, and low loss. The products feature excellent and reliable performance, with a peak isolation of up to 45 dB, a maximum aperture of 45 mm, and typical transmission values reaching 95%. Customization is available for all products

250MSps dual-channel high-speed data DAS acquisition card

The PCIe-6920 is a high-speed data acquisition card with a PCIe x8 Lane interface, dual channels, and a 14-bit resolution at a sampling rate of 250MSps. It features an onboard high-performance FPGA chip with abundant multipliers and RAM resources. Using large-capacity data buffering and high-speed data transfer engine technology, it supports real-time uploading of raw data, with a data transfer rate of up to 2GB/s. The driver software is highly compatible and supports multiple versions of WIN7, WIN8, and WIN10 (32/64-bit). DAS (Distributed Acoustic Sensing) and DVS (Distributed Vibration Sensing) are relatively new technological directions in recent years. Compared to DTS (Distributed Temperature Sensing), they require higher technical standards and more advanced devices. In particular, the system's ADC requirements are demanding, needing high sampling rates and high precision, as well as long-term stability. Currently, our company provides high-speed A/D converters (sampling rates up to 1 GS/s, 16-bit) for DAS and DVS systems.
