ST SM 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 FC Fiber Optic Attenuator is able to couple from FC connector to FC connector, while male to female FC Fiber Optic Attenuator from FC adapter to FC connector. The combination of attenuation film in female to female FC attenuator or attenuation fiber in male to female FC attenuator and precision molded polymer/metal housing provides reliable and stable optical attenuation performance.

Selection Notes

Typically selected when an ST/UPC single-mode link needs a fixed, known attenuation value (up to 25 dB) to prevent receiver overload or to stabilize power during commissioning/testing, using a male-to-female plug-in format for quick insertion at patch points.
May not be appropriate when the required attenuation target or wavelength plan (1310/1550) isn’t defined, or when the link is not actually single-mode ST/UPC, since an incorrect fixed value can under-power the receiver or hide underlying link issues during troubleshooting.
