 LC/UPC Single Mode Fixed Fibre Optic Attenuator, Male-Female, 7dB.

Our Passive attenuators are mainly used in fibre optic testing to debug optical power performance and optical instrument calibration correction. The fibre signal attenuation is to ensure the optical link and data transmit/receive while reducing power in a stable and desired level in the link without any changes on its original transmission wave.

The operating wavelength  1250 ~ 1650nm

Return loss >45db
