These work well at reducing light levels on fttx type installs.

These worked exactly as expected. They snapped in easily and appear to deliver the correct attenuation. No problems so far.

Needed the reduce signal on single-mode fiber SC connector. Good stuff.

The media converters I bought were designed for much longer distances than they were used for, and the signal arriving at the receiver was too strong, this attenuator helped to reduce the optical fiber power, and now the problem has been solved.

I've been using it for a few days now. The attenuation values are as accurate as described, and the link works well.
