OPTICAL TIME-DOMAIN REFLECTOMETER |
摘要 |
<p>A optical time domain reflectometer (OTDR) which sends and receives pulses for multiple frequencies down a fiber under testing (FUT). These frequencies can include frequencies for testing a live FUT and frequencies for testing a dark FUT. The pulses of the various frequencies are sent and received through a single optical connection with the FUT. The number of connections necessary to test the fiber is thus reduced. The OTDR may also include a built in passive optical network (PON) power meter, which measures the power level of the fiber over the same single optical connection.</p> |
