SC Plug-IN Fixed Fiber Optic Attenuator

Fiber optic attenuator is able to reduce optical power and limit the optical power received by the photodetector within the limits of the optical receiver. We offer a wide range of fiber optic attenuators, SC attenuator, FC attenuator, LC attenuator, ST attenuator, etc. Fixed Fiber Optic Attenuator has different attenuation values from 1dB~30dB, 5dB attenuator, 10dB attenuator, 15dB attenuator, 20dB attenuator, 30dB attenuator for example. Fixed Fiber optic attenuator has female to female adapter type attenuator and male to female plug-in type attenuator. Female to female SC Fiber Optic Attenuator is able to couple from SC connector to SC connector, while male to female SC Fiber Optic Attenuator from SC adapter to SC connector. The combination of attenuation film in female to female SC attenuator or attenuation fiber in male to female SC attenuator and precision molded polymer/metal housing provides reliable and stable optical attenuation performance.

Selection Notes

Typically selected when an SC/UPC single-mode link needs a fixed, known attenuation value (up to 25 dB) to prevent receiver overload or to normalize power levels during commissioning/testing, using a male-to-female plug-in format for quick insertion at ODF/patch points.
May not be appropriate when the attenuation target, wavelength plan (1310/1550), or the site’s SC/UPC vs SC/APC convention isn’t clearly defined, since an incorrect fixed value or polish mismatch can under-power the receiver or hide underlying link issues during troubleshooting.
