Allows you to detect traffic and measure signals anywhere on singlemode fibers without having to disconnect them.

No more network outages as a result of fiber detection/identification procedures

The minimized need to access the network helps prevent errors

• Induces minimal loss: ≤1 dB
• Fail-safe detection and results
• Detects if a fiber is active or not prior to maintenance
• Locates a particular dark fiber using tone recognition (270 Hz, 1 kHz, 2 kHz)
• Identifies traffic direction on a live fiber
• Displays the power transmitted through the fiber
• Three times faster test time
