Ethernet cable surge suppressor?

Without commenting on the situation required for one to be necessary, is there such a thing as a surge suppressor for an ethernet cable?

 

I have never looked into this until now, but yes, they do Here are some examples:

Surge Protector with ethernet "data line" protection http://www.belkin.com/surgeprotection/concealed/

UPS with network protection http://catalog.belkin.com/IWCatProductPage.process?Product_Id=186802

not sure if there is much of a use for these in the average home, but you might have your reasons

 

Thank you sir. I'm going to purchase the fancy one with battery backup
