DSL Filter Innovation, Performance & Selection

Innovation led to our invention of the DSL filter back in 1999, and this forward-thinking mentality continues today, with high-quality xDSL filters that deliver the highest data rates and clearest phone conversations. Our xDSL filters/splitters are ideally suited for Central Office and Customer Premise Equipment applications, ensuring the following benefits:


  • Ensure clear, “echo-free” phone conversations.
  • Work with Caller ID despite the installation of three or more filters.
  • Are designed to coexist with alarm panels.
  • Meet ANSI, ETSI, and ITU performance standards demanded by many telephone companies.
  • Use high-gold RJ connectors that will resist corrosion, prevent phone-line noise, and preserve your modem’s data rate potential.
