Extron electronic FLS 101, FPM 101 manual Output Ports and Indicators, Output Wavelength Selection

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.

EMM output port — LED source multimode optical output.

FSM output port — Laser source singlemode optical output.

GActive 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

H850/1300/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.

I1310/1550/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.

JTone 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.
