Before OTDR Testing
Fiber preparation
The Smart OTDR works on any single mode fibers , but it does not work for multi mode fibers . The single mode fiber means
it is with 9 um core . The multi mode fiber means it is with 62 .5 um or 50um core . And because of OTDR testing theory,
please be sure the fiber is not very short , at least 3 meters , and not greater than 90km.
Fiber Connector
There are two kinds of fiber connector, one is APC with 8oangle , the other is UPC ( PC) horizontal angle .Users are not
allowed to change between them . The OTDR port is installed with SC connector in factory default .If users want to change
SC connector to FC connector, it is allowed . Unscrew SC connector and pull it out in vertical direction .Then screw FC
connector into OTDR port . Please check if the key on FC connector locked into slot exactly in OTDR port .
Connector Cleaning
Please use connector cleaner to clean OTDR port and fiber connector. Please take off entire dusty cap on the tip of cleaner
when you clean OTDR port . W hen you clean fiber connector, just take off top half dusty cap on cleaner tip .
