ST (F) to FC (M) Multimode Plug-in Fixed Attenuator

Feature Details:

• Stable Attenuation: Fixed attenuation value for stable signal reduction.
• Plug-and-Play Design: Without splicing, making installation fast and hassle-free.
• Wide Fiber Compatibility: Works with single-mode and multimode fiber.
• Durable Build: Equipped with a ceramic ferrule and robust metal housing to withstand repeated use.
• Multiple Options: Available in different attenuation levels, meeting diverse testing and deployment needs.

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.
