Abstract

Disclosed is a means for testing drop wires in digital loop systems which employ optical fiber up to a distant terminal near the subscriber's premises. A test module is provided at the distant terminal to determine the presence or absence of faults on the wires to the customer premises. The results of the test are transmitted via an optical data link to the remote terminal where the results can be accessed by a loop tester at the central office.
