Applications
Range Finders: Provides stable 1550nm wavelength for precise distance measurement in industrial and aerospace applications. Optical Transmitters: Supports 2.5Gb/s data rate for digital and analog signal transmission in fiber optic communication systems. Optical Bidi Modules & Transceivers: Integrated isolator and monitor diode simplify module design for telecom and datacom equipment manufacturers.
Key Features
--Why Choose Our Laser Diode for B-end Applications? 1550nm DFB Technology: Distributed Feedback (DFB) structure ensures narrow spectral width (-3dB spectral width: 0.3~0.5nm) and stable wavelength, critical for high-precision range finders and optical transmitters. Integrated Optical Isolator: Provides ≥30dB isolation, reducing signal interference and improving system reliability-essential for bulk deployment in optical networks. Built-in InGaAs/PIN Monitor: Real time monitoring of output power (monitoring current: 100~1000uA at CW, If=Ith+20mA) simplifies system calibration for B-end users. High Reliability: Operating temperature range of -20~70℃ and storage temperature of -40~85℃, ensuring durability in harsh industrial environments. Industrial-Grade Specifications: Designed to meet strict electrical and optical standards, with slope efficiency ≥0.125 W/A (CW, If=Ith+20mA) and fast response (rise/fall time ≤120ps), suitable for high-speed optical transmitter applications.
