Quad Channel DWDM EDFA

The quad integrated DWDM EDFA (Dense Wavelength Division Multiplexing Erbium-Doped Fiber Amplifier) offers significant advantages in optical communication transmission systems through highly integrated design and optimized performance:

• Space and Cost Efficiency: Integrating four independent EDFA functions into a single module or chassis drastically reduces footprint, ideal where rack space is limited, easing physical installation constraints. Integrated design reduces redundant components like separate power supplies and control circuits, lowering overall hardware costs. Centralized power and management decrease energy consumption and maintenance effort, optimizing lifecycle cost.

• Excellent Signal Transmission Performance: Tailored for DWDM multi-channel, it uses fine gain flattening techniques to ensure minimal gain variation among the four channels within the 1550nm window (typically ≤1dB), preventing power imbalance during amplification and ensuring signal integrity over long distances. Features high output power (typically >20dBm per channel) and low noise figure (typically ≤5dB), providing sufficient signal strength for long-haul transmission while minimizing noise impact, supporting stable amplification for 10G/40G/100G high-speed signals per channel.

• Strong System Compatibility and Scalability: Designed to comply with DWDM international standards with highly adaptable interfaces for seamless integration into mainstream WDM systems without major architectural changes. The four independent channels support flexible wavelength configuration, allowing dynamic adjustment of wavelengths and rates per channel based on service demands, meeting bandwidth expansion needs.

• Wide Operating Temperature Range (typically -5°C to 55°C), coupled with overcurrent and overtemperature protection, ensures stable operation in complex environments. MTBF can exceed 100,000 hours, providing strong support for continuous communication system operation.
