Testing Splitters

The demarcation point has moved upwards into the home since the Service Providers deliver services to the desktop.

Services like IPTV and Gaming are very much depending on the quality of in-home networks and are sensitive to disturbers that might cause unacceptable interruptions screwing up the quality of the service delivered at the door. For that reason the effect of splitters on the performance of DSL has become a major issue. More than ever the Service Providers are concerned about the nature of specific problems on the physical layer that differ from country to country and network to network. Sparnex Instruments' 30 years of experience in physical layer has result in a range of sophisticated programmable test and simulation solutions that mimics accurately these problems allowing Service Providers to qualify the best possible solution that guarantees them to deliver an acceptable quality of service to their customers.

The new generation of the Sparnex Instruments splitter testers are especially designed to avoid that Loop Simulators influence the test results in order to test DSL up to its true limits in presence of splitters stressed with door bells, ring currents from phone sets and other in-home disturbers.

Sparnex Instruments Splitter Test System SFT 127


Testing multiple DUT with the SFT 127-M

Using the ASM 525, the SFT 127-M setup enables the user to combine the test of multiple CPE/CO splitter/filters in a single automated test run.
This will even further reduce the amount of time and resources used in testing the WT-127.  It allows for un-attended 24x7 testing.
