Feature:1. The fiber adapter connector has good repeatability, good wear resistance and good temperature stability.2. The average additional loss of this adjustable attenuator is less than 0.2dB, high return loss, and more than 1000 plug-in cycles.3. Under the premise of 5S standardization and scientific management, it will be delivered at a faster speed and strictly tested before leaving the factory to ensure normal use.4. Effectively suppress ground loop noise, eliminate ground interference, and effectively isolate the signal field from the main control terminal.5. This mechanically adjustable attenuator avoids accidental damage to the main control terminal.Specification:Item Type: Optical Fiber ConnectorMaterial: ABS, ceramic, stainless steelEnvironmental Humidity: 95RHAccurate Attenuation: ≤±0.5dbFerrule Type: CeramicWavelength Parameters: Single mode 1310~1550nmWorking Temperature: -40℃-80℃Product Return Loss: ≥55dbStorage Temperature: -55~85℃Environmental Test: Continuous collision (4000 times) insertion change is less than 0.2dB, reflection is greater than 35dBDrop Test: Insertion change is less than 0.2dB, reflection is greater than 35dBBend Test: Insertion change is less than 0.2dB, reflection is greater than 35dBDistortion Test: Insertion change is less than 0.2dB, reflection is greater than 35dBDifferential Durability Test: Insertion change is less than 0.2dB, reflection is greater than 35dBTensile Test: Insertion change is less than 0.2dB, reflection is greater than 35dBConnector Adaptation Resistance: 200-400gf 200-400gfVibration Test: Insertion change is less than 0.2dB, reflection is greater than 35dBSalt Water Spray Test: Insertion change is less
