5.1 Test Ports and Interfaces
OTDR testing: The optical fiber under test is connected to either the OTDR or OTDR Aux
(Filtered SM or MM) port on the top panel. The type of the optical fiber connector must
correspond to the OTDR connector or adaptor type, including the connector polish.
Optical Power Meter (OPM) testing: The optical fiber is connected to the OPM port on the
top panel. Depending on fiber connector type, use interchangeable adaptors. FC, SC, ST or
LC type are supplied standard.
Visual Fault Locator ((VFL) testing: The optical fiber is connected to the VFL port on the top
panel. The VFL interface is fitted with universal 2.5mm sleeve accepting all 2.5 mm connector
ferrules.
Note:
Optical Connections - The optical fiber connector must be cleaned prior to connecting to the
fiber under test. Dust and dirt severely impacts optical performance.
Refer to Fiber handling procedures for cleaning tips and information.
