Description
— Hand-held, easy to operate
— Automatically shut down can be set
— Burst mode test for 1310nm upstream wavelength
— Measurement and alarm thresholds can set
— Support the synchronous measurement and display of experimental voice, data and video signals on PON architecture
— Upstream signal 1310nm, downstream signal 1490nm and 1550nm in PON system can be measured at once
1. ONT: upstream signal 1310nm detection port
2. OLT/VIDEO: downstream signal 1490/1 550nm detection port
3. USB: mobile power supply available, non charging
4. Display Screen
5. ON/OFF&Auto shutdown key
7. THR: set the threshold
6. REF: set reference power
8. ▼/LOAD: save or view the saved results
9. ▲/UNIT: switch display unit dBm/dB/mW
10. SEL: in threshold set mode, switch the lower limit of threshold
and the lower limit of alarm in threshold group; in the view interface, switch to saved items.
