Description Fiber Attenuator, ST Single Mode Simplex with UPC Polish ST/UPC single mode fiber attenuators are commonly used in fiber optic communications to the the power level of a fiber cable by controlling the amount of signal loss that is passed through the signal. ST/UPC single mode fiber optic attenuators can also be used on a more permanent basis in order to match the signal with a transmitter and receiver's specific power levels. Features Features Metal ion doped fiber High-power light source durability Wavelength independence Attenuation levels ranging from 1dB to 25dB 1310nm, 1550nm and 1310/1550nm dual wave lengths Specifications SPECIFICATIONS Maximum Return Loss ≥50 dB Attenuation Levels from 1dB to 9dB ±10%dB Attenuation Levels from 10dB to 30dB ±1.0%dB Additional Information Applications Erbium Doped Fiber Amplifiers (EDFA) Dense Wave Division Multiplexers (DWDM) Overpowered fiber optic systems What's in the Box What’s in the Box Qty 1 - Fiber Attenuator, Single Mode ST/UPC Simplex, 1dB Qty 1 - Protective dust cap for ST/UPC connector
