*Warning
Never look directly into optical
output connectors (B and D).
Some sources produce invisible
radiation that can permanently
damage your eyes.
A
Button for activating the visual fault locator (B) and output port (D). See
Chapter 8 and “Autotest in Far End Source Mode” on page 7-18.
B
Universal fiber connector (with dust cap) for the visual fault locator output.
The connector accepts 2.5 mm ferrules. The LED below the connector
indicates the locator’s mode (continuous or blinking).
C
Input connector with dust cap. Receives optical signals for loss, length, and
power measurements. You can change the connector adapter to match the
connectors on the fiber under test. See Figure 7-3.
D
SC output connector with dust cap. Transmits optical signals for loss and
length measurements.
The LED below the connector is red when the output is transmitting the
module’s shorter wavelength, and green for the longer wavelength.
E
Laser safety label (shown at right).
