Detailed Description
Name:SC Adaptor type attenuator SC adapter (female to female) type optical attenuator Fiber Optic Attenuator is a component installed in a fiber optic transmission system that reduces the power in the optical signal. It is often used to limit the optical power received by the photodetector to within the limits of the optical receiver. Features: Low back reflection and Low PDL High precision attenuation value Precision control of attenuation range Wide attenuation range Precision ceramic ferrule FC, SC, ST, LC … optional Plastic or metal housing material Application: Fiber optical telecommunication system Fiber optical CATV Fiber optical sensor Testing equipment Parameter: Item Unit Parameter Operating Wavelength Nm SM:1310/1550nm MM: 850 /1300nm Attenuation Range dB 1-10dB(1dB step), 15, 20, 25, 30dB Return Loss dB PC:≥50 UPC: ≥55 APC: ≥60 Attenuation Tolerance dB ≤+/-0.5(1-10dB) or ≤+/-1.0(11-30dB) Working Temperature ℃ -25℃~+75℃ Storage Temperature ℃ -40℃~+ 85℃
