EDFA Multichannel intermediate stage erbium-doped fiber amplifier
■Product Description
The product is multi-channel EDFA of support dispersion compensation modules insertion, high flattening and high stable output. The product can amplify of before and after by double-pumped, offset the insertion loss dispersion compensation module and has the better transmission performance index than unipolar amplification of high gain. 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
■ Product features
♦ Low-noise high flatness design
♦ Pluggable Dispersion Compensation 20~100km
♦ Adjustable output power
♦ High precision ATC keep system stable operation
♦ Precision ADC / APC circuit keeps the output Power stability
♦ Card design highly integrated, space-saving cabinet
♦ Expansion is very convenient
