EDFA Multi-channel erbium doped fiber amplifier 

■Product Description

The product is multi-channel EDFA of  high flattening and high stable output.  The kernel component of the product is high availability pump laser and high-performance gain flattening filters. The product has high stable output, high gain flatness and high reliability by using unique APC (automatic power control) and ATC (automatic temperature control). The system’s flatness and noise can achieve the best optimization by the gain flattening filters of professional design. The system is convenient to regulation and display, reliable, intelligent by using high stable and high precision MPU.

■Applications

♦       C-band 40/80CH DWDM

♦       Other optical systems
