Not only the instrument will display measured optical power value on LCD screen, but also under P/F test
mode its three LED indicators will function with following meanings:
The three LED indicators represent upstream 1310 nm (ONU), downstream 1490 nm (OLT) and 1550 nm
(Video) respectively. The RED color indicates Fail, ORANGE color is Warning and GREEN color means
Pass.
The definitions for the three states (Fail, Warning and Pass) are described as below:
If assuming the instrument’s measuring upper limit as and lower limit as , the “Pass” threshold
value in instrument’s internal setup are , as Warning threshold and as
Fail threshold, . value represents
measured optical power, then:
1.If , means the power is , the will indicate in ;
2.If means , the will indicate in ;
3.If , means , the will indicate in ;
4.If , means , the will indicate in ;
5.If , means , the will indicate in ;
6.If , means the power is High, the will indicate in .
