ECSite Smart Load™

The ECSite Smart Load™ is a Bluetooth-enabled, remotely programmable open/short/load/through (Remote OSLT) telecom cable tester. 

Attached to the far end of a coax cable, it allows a single technician to fully verify every aspect of the cable’s operation and quality from one location. 

With a 50-foot Bluetooth range, the technician can switch the cable tester’s functions from a companion mobile app. If further range is needed a controller module can be included to control the tester via bidirectional communication directly through the coax cable. 

Open, short, and load operations facilitate measurements of insertion loss, distance-to-fault, and return loss, while through mode allows far-end equipment to be connected and verified. 

Using the ECSite app with a suitable cable and antenna analyzer, the operator can sequence through all cable tests and record the results rapidly and accurately, allowing faster, more precise COP completion.
