1.25mm LC Connector Fiber Optic Cleaner and MU LC Fiber Optic Cleaning Pen

Fiber Optic channels have a remarkable data capacity – they may actually have the highest data throughput density available for any medium currently in use. But they do require the system infrastructure to support this medium. Once in a while, the data throughput may show curious signs of degradation often causing end users to scratch their heads... And this is usually due to some microscopic foreign object interfering with the optical signal path.That's where pens such as these come in.The good, simple operation – and follows a known industry standard. Does the job, and does it well. High capacity for number of available cleanings.The bad: None I can think of.Bottom line: Good investment for anyone working with optical data paths. This one works well. 5 stars.

These are cheap but they do work

Had two lc one clicks was broke when pulled out of the package

This may not hold up to a lot of professional use, but is a great value for someone that just has this need occasionally.
