Description
Features of Fiber Optical Attenuator
- Reliable performance, stable attenuator technical indicators meet industry standards
- All-fiber structure, good environmental stability, low polarization-related loss
- Can effectively suppress ground loop noise and eliminate interference
- Effectively isolate from the main control end in electricity to prevent accidental damage to the main control end
- Plug-in times greater than 10,000+, good flame retardancy, reaching UL94V0, high temperature resistance and environmental protection, compliant with ROHS requirements, and high impact resistance.
