- FTTH Networks: Prevents signal overload in fiber-to-the-home installations.
- Optical Distribution Frames: Supports accurate signal management in complex networking environments.
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.
