The ST820B optical fiber identifier also recognize the modulation like 270Hz, 1kHz and 2kHz .When they are used to detect the frequency, the continuously audible tone is activated.
Adapters:
There are four adapter heads available: Ø0.25, Ø0.9, Ø2.0 and Ø3.0.
Key Features:
1. Easy-to-use with “ONE KEY” operation.
2. Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) with audible warning.
3. Displays the relative core power
4. More accurate test with sunshade
5. Easy-to-replace adaptors
6. Durable metal housing and quality construction
7. Lower power indication
Application:
- Telecom Projects
- Optical Fiber CATV
- Generic cabling system
- Production and research of optical components
