FAQs

Q: Is this attenuator suitable for 100G and 400G links?
A: Yes. It is passive and wavelength-agnostic within 1260–1625 nm, compatible with 1G–400G single-mode optics.

Q: What LC polish type is used?
A: LC/UPC. Use with UPC-terminated patch cords and panels for best performance.

Q: Is it male-to-female or bulkhead?
A: This is a bulkhead (female-to-female) fixed attenuator for panel or inline coupler use.

Q: Can it be used on multimode fiber?
A: No. It is designed for single-mode (OS1/OS2) wavelengths.
