China Suppliers Factory: Dual Channel DWDM EDFA with Compact Design, High Power, Low Noise & Customization
Product description
Dual integrated EDFAs offer advantages like high integration, stable performance, and flexible functionality:
High Integration
Integrates two EDFA channels into a single module/device, compact structure. Significantly reduces volume and footprint compared to two separate EDFAs, saving rack space, lowering installation costs, and simplifying system integration and cabling.
Independent Control & Flexible Configuration
Each EDFA channel can be controlled independently. Users can set parameters like gain and power for each channel separately based on needs, adapting flexibly to different optical path requirements and service scenarios (e.g., different wavelength channels or transmission distances).
High Performance Metrics
Typical NF ≤5.5dB. Utilizes professionally designed GFF (Gain Flattening Filter) and optimized optical design for low noise figure, reducing added noise during amplification, improving signal quality, ensuring transmission accuracy and stability. Suitable for scenarios demanding high signal quality like high-speed data transmission. High Gain & Flatness: Provides high gain with good flatness, maintaining uniform gain across a broad wavelength range. Ensures effective and balanced amplification for both channels at different wavelengths, reducing signal power imbalance, improving system link loss budget.
Stable and Reliable
Advanced Thermal Control: Typically features intelligent thermal management (e.g., dedicated thermal control chips), reducing device heat generation by up to 30% compared to conventional circuits, ensuring thermal stability, extending internal component lifespan, and improving overall reliability. Precise Power Control: Uses highly reliable Pump lasers with unique APC circuits for precise output power control (typical accuracy ±0.01dB), ensuring high output power stability and minimizing impact from power fluctuations.
Convenient Management
Equipped with comprehensive status monitoring interfaces (e.g., LVTTL, RS-232), connectable to network management systems for remote monitoring and management. Allows operators to check status, set parameters, and troubleshoot efficiently.
