Product Description

Product Features

Engineered for precision and long-term reliability, the High Stability 300mW 1064nm In-line Isolator is designed to deliver exceptional optical performance while minimizing procurement and integration risks. By combining superior back-reflection protection with a highly adaptable physical footprint, this component ensures that your laser systems operate at peak efficiency. Below are the core advantages that make this isolator a preferred choice for demanding optical environments.

• Versatile Single and Dual Configurations for Optimized Isolation: Depending on your project requirements, this isolator offers flexible setup options to balance cost and performance. The single-stage configuration delivers a typical isolation of 35dB, ideal for standard optical routing and general applications. For high-interference environments where severe back-reflections pose a threat to sensitive laser diodes, the dual-stage configuration provides an outstanding typical isolation of 52dB, ensuring maximum protection and system longevity.

  
  

• Ultra-Low Insertion Loss for Enhanced Transmission Efficiency: Signal attenuation is a critical concern in precision optical setups. With a typical insertion loss of just 1.5dB (for the single configuration), this device preserves signal integrity and minimizes power waste. This high transmission efficiency means your source laser can operate at lower power levels to achieve the desired output, thereby reducing thermal load, lowering energy consumption, and extending the overall lifespan of the optical system.

  
  

• Superior Environmental Stability and Consistent Performance: Industrial and field applications often expose optical components to fluctuating conditions. This 1064nm isolator operates reliably across a broad temperature range from -5°C to +50°C. Furthermore, it features a maximum Polarization Dependent Loss (PDL) of only 0.15dB. This exceptionally low PDL ensures that any variations in polarization do not translate into amplitude noise, guaranteeing stable, continuous operation and significantly reducing the need for maintenance downtime.

  
  

• Reliable 300mW CW Power Tolerance for Medium-Power Systems: Specifically tailored for medium-power 1064nm laser setups, this component boasts a robust 300mW Continuous Wave (CW) power handling capability. This safe operational margin prevents common issues such as thermal lensing, signal saturation, and optical damage that frequently occur when using underrated components. Buyers can confidently integrate this isolator into their systems, knowing it will maintain stability under continuous load.

  
  

• Flexible Customization to Streamline System Integration: To accommodate diverse engineering demands, we offer extensive customization options. Buyers can specify either polarization-maintaining (PM) or single-mode (SM) fiber types, select from multiple industry-standard connector choices, and define exact fiber pigtail lengths. This adaptability ensures seamless mechanical and optical matching, eliminating the need for additional adapters that could introduce unwanted insertion loss or structural complexity.

  
  

• Standardized Compact Package for Effortless Retrofitting: Space constraints are a major consideration in modern, densely packed optical modules. Featuring standardized Φ5.5×35mm dimensions, this compact package aligns perfectly with industry norms. This allows engineers to easily retrofit the isolator into existing optical chassis or integrate it into new designs without requiring extensive layout modifications, thereby accelerating assembly timelines and reducing engineering overhead.

  
  

Product Applications

The High Stability 300mW 1064nm In-line Isolator is an essential component designed to safeguard sensitive optical systems from the detrimental effects of optical feedback. By effectively blocking reverse light and back-reflections, this device ensures the continuous and stable operation of laser sources and optical amplifiers. For procurement professionals and system engineers, selecting a reliable isolator is critical for minimizing equipment downtime, reducing maintenance costs, and extending the operational lifespan of expensive optical infrastructure.

• 1064nm Optical Communication Systems

  In the realm of optical communications, maintaining signal integrity is paramount for both long-haul networks and short-range optical links. Back-reflections from connectors, splices, or other passive components can introduce severe reverse signal noise, leading to increased bit error rates and degraded transmission quality. This 1064nm in-line isolator acts as a critical barrier, effectively blocking reverse signal noise and preventing it from reaching the transmitter. By ensuring that the laser source operates without interference from optical feedback, it helps maintain a clear, stable transmission channel. For network operators, integrating this isolator means enhanced system reliability, fewer data transmission errors, and a more resilient communication infrastructure capable of handling high-capacity demands.

  
  

• Precision Optical Test Instruments

  Accuracy and consistency are the foundations of precision optical testing. When validating laser components or evaluating overall optical system performance, any instability in the test light source can compromise the measurement results. Optical feedback is a common cause of laser mode hopping and power fluctuations. By incorporating this in-line isolator into precision optical test instruments, engineers can guarantee that the laser source remains completely isolated from downstream reflections. This protection ensures that the measurement data reflects the true performance of the components under test, rather than anomalies caused by back-reflections. It provides a dependable foundation for quality control, calibration, and performance validation procedures, ultimately reducing the risk of false readings and ensuring strict compliance with industry testing standards.

  
  

• Fiber Optic Sensing Systems

  Fiber optic sensing systems are widely deployed in critical applications such as infrastructure structural health monitoring, resource exploration, and industrial process detection. These environments often involve complex fiber routing and numerous connection points, increasing the likelihood of strong back-reflections. Operating at a mid-power level of 300mW, this 1064nm isolator provides the necessary optical isolation to enhance the stability of the sensing laser source. By preventing reflected light from destabilizing the interrogation unit, it ensures continuous, high-fidelity data acquisition even in harsh or unpredictable environments. For project managers and system integrators, utilizing this isolator translates to improved sensor accuracy, reduced risk of sudden system failures, and enhanced long-term reliability for critical monitoring networks.
