Applications

CATV Systems: As a reliable InGaAs APD for CATV, this diode delivers low dark current (≤10nA) and high optical return loss (≥40dB) to eliminate signal noise and reflection. It ensures clear transmission of digital TV signals across miles of fiber, making it ideal for CATV equipment manufacturers procuring components for bulk network deployments. OTDR Equipment: For OTDR photodiode procurement, the BLAPD-PFA1-50AR's high responsivity (0.75A/W) and multiplication factor (≥10) enable accurate detection of fiber optic faults (e.g., breaks, attenuation). LIDAR Technology: With 2GHz bandwidth and low capacitance (≤0.5pF), this diode is a top choice for LIDAR InGaAs APD procurement. It captures high-speed optical signals to support real-time 3D mapping in autonomous vehicles, drones, and industrial robots.

Key Features

High Responsivity: At 1310nm (M=1, φe=1μW), it ensures accurate weak-signal detection – critical for OTDR photodiode applications requiring long-distance fiber fault monitoring. This eliminates post-purchase debugging, reducing your production downtime. Low Dark Current: Minimizes signal noise in CATV InGaAs APD systems, guaranteeing clear TV signal transmission across large networks. Low Capacitance: Optimized for high-frequency performance (tested at Vr=Vbr-3V, f=1MHz), ensuring compatibility with your existing high-speed circuits. Laser Welding & Long Lifespan: Enhances mechanical stability and operational durability, lowering maintenance costs for clients with large-scale installations. Universal Mounting & RoHS Compliance: The universal type mounting fits most standard fixtures, while RoHS certification meets eco-friendly procurement requirements for global markets.
