1. Indicate the signal directions and power in fiber
2. Indicate the signal presence or absence(Live or dark fiber)
3. Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) with audible warning
4. Displays the relative core power
5. Don’t need to replace adaptor
6. Lower power indication
7. Build in 10MW VFL function
