Output Ports and Indicators
The optical output ports require adapter caps for connection to fiber optic links and reference
cables. The FLS 101 includes two LC adapter caps.
e
MM output port — LED source multimode optical output.
f
SM output port — Laser source singlemode optical output.
g
Active output indicators (lit when the corresponding output port is On) — The active
output indicators light as follows:
Test Mode Active Output Indicator Status
WAVE ID, dual wave Corresponding wavelength indicator is lit,
alternating between the two active wavelengths
WAVE ID, single wave Selected wavelength indicator is lit
CW or tone Selected wavelength indicator is blinking
Output Wavelength Selection
h
850/1300/CW button — Multimode wavelength select button provides functions as follows:
WAVE ID Mode
Press and release the button to cycle through output wavelengths in the following order:
Dual 850/1300 nm > 850 nm > 1300 nm > Dual 850/1300 nm > ...
The corresponding MM active output port indicators light.
CW Mode
• Press and hold the button to switch to the CW mode. Press and hold the button again to
select a single wavelength in the following order:
850 nm > 1300 nm > 850 nm > ... Release the button when the desired wavelength port
indicator turns on. The selected MM active output port indicator blinks.
• Press and release the button to return to the WAVE ID mode.
i
1310/1550/CW button — Singlemode wavelength select button provides functions as follows:
WAVE ID Mode
Press and release the button to cycle through output wavelengths in the following order:
Dual 1310/1550 nm > 1310 nm > 1550 nm > Dual 1310/1550 nm > ...
CW Mode
• Press and hold the button to switch to the CW mode at the current wavelength. Press and
hold the button again to select a single wavelength in the following order:
1310 nm > 1550 nm > 1310 nm > ... Release the button when the desired wavelength
port indicator turns on. The selected SM active output port indicator blinks.
• Press and release the button to return to the WAVE ID mode.
j
Tone button and Indicator —
Tone button (1550 nm, SM only) — Press the tone button to toggle the 2 kHz tone function
on/off. When the tone mode is disabled, the unit returns to the WAVE ID mode at the currently
selected wavelength.
NOTE: When the tone feature is active, WAVE ID is disabled and the output level is
reduced by 3 dB.
Tone indicator — The Tone indicator is lit when the FLS 101 is transmitting in tone mode.
