APPLICATION DETAILS
- Telecom Networks: Balances optical power in short multimode fiber links to prevent overload.
- Data Centers: Used in high-density environments to maintain optimal multimode transmission quality.
- FTTH/FTTB Projects: Ensures correct signal levels during installation and troubleshooting.
- Testing & Measurement: Ideal for laboratory, R&D, and production line testing of optical components.
- Enterprise Networks: Provides controlled attenuation for LAN and campus fiber optic connections.
Selection Notes
- Typically selected when a short multimode link needs a fixed attenuation value (1–25 dB) and the setup requires a hybrid plug-in format (ST female ↔ FC male) to interface directly with mixed test gear or legacy ports without adding extra patch cords.
- May not be appropriate when the link is actually single-mode, or when the attenuation target / wavelength plan isn’t defined, since a wrong fixed value (or wrong fiber-mode assumption) can under-power the receiver or hide real link issues during troubleshooting.
