The KE3550 xDSL MultiTest offers high performance and a wide range of functions at an affordable price. The new version 2 contains several improvements compared to its predecessor, including more powerful hardware and optimized edge protection.

The KE3550, specially developed for use in copper-bound broadband networks, offers ICT specialists and service technicians interfaces for DSL and Ethernet even in its basic version and supports ADSL - ADSL2+, Annex B/J, VDSL2 and VDSL2 Vectoring / Super Vectoring with automatic detection of the xDSL service. The compatibility with the DSL high-speed module for makes the KE3550 an expandable and future-proof investment. Thanks to the revolutionary one-view display and the ability to perform multiple tests simultaneously, complicated and time-consuming measurement procedures are a thing of the past.

The KE3550's modular platform supports additional features such as ISDN and analog test phones, triple play tests for IPTV and VoIP suitability, and the ability to perform extensive copper tests up to 31 MHz. The integrated high-performance rechargeable battery ensures long field use.
