Description Overview GAOTek U C-band DWDM EDFA Amplifier supports dispersion compensation modules insertion, high flattening, and high stable output. The product can amplify before and after by double-pumping, offset the insertion loss dispersion compensation module and has a better transmission performance index than unipolar amplification of high gain. 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. Features Low-noise high flatness design Adjustable output power High precision ATC keep system stable operation Precision AGC or APC circuit keeps the output Power stability Card design highly integrated, space-saving cabinet Expansion is very convenient Requirement for design Technical Specification Work wavelength range(λ) 1546.12 nm to 1561.42 nm No. of Working channel 1 CH to 44 CH Input power range -35 to -10 dBm Output power range -10 to 17 dBm Gain 14 to 33 Variable Output Power Rang 0 dBm to 20 dBm Output power stability ±0.5 dBm Noise figure ≤5.0 dB Gain flatness 0.6 dB to 1.5 dB Reflection loss Input terminalOutput terminal >=45 dB>=45 dB Power supply voltage AC 160 V to 250 V (50 Hz) or DC 48 V Maximum operating relative humidity Max 95% no condensation Maximum storage relative humidity Max 95% no condensation Operating temperature range 18 °F to 131 °F (-5 °C to 55 °C) Storage temperature range -22 °F to 158 °F (-30 °C to 70 °C)
