Description

FF-3306D Optical Fiber Identifier is an important tool for optical fiber network maintenance, which is used for nondestructive fiber identification work, can be detect in any location of both SM and MM fiber. Meanwhile it also has Visual Fault Locator module with fault location function. It is the ideal instrument for online test.

 
Function:

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 power level;

5.Easy-to-replace battery;

6.Lower power indication;

7.Build in VFL function.

From a telecom operations perspective, FirstFiber's FF-3306D Fiber Optic Identifier provides complete online testing functionality in a lightweight 200g package measuring 230 x 43 x 48 mm. The clear LED display and audible warning tones make identifying specific fibers straightforward during complex rack trace jobs. Having a powerful 10mW VFL built into a $95 instrument removes the need to carry separate fault locators. Operating reliably across temperatures from 0°C to +50°C, it offers outstanding practical utility for network maintenance crews.

Testing the FF-3306D Fiber Optic Identifier for routine maintenance on live single-mode and multimode links, the non-destructive macrobend clamp detects traffic without interrupting active transmission. It clearly indicates signal direction, relative power levels, and live vs. dark fiber status, while audibly identifying 270Hz, 1kHz, and 2kHz frequency tones. The integrated Visual Fault Locator module features a 650nm center wavelength with 10mW output power for quick fault identification. At $95 USD (SKU: FF-3306D), this handheld identifier is an essential, high-value tool for field technicians.

The FF-3306D is a reliable optical traffic detection tool for cabling under 3mm in diameter. Equipped with a 1mm InGaAs detector, it offers high sensitivity with minimum detection power down to -35dBm at 1550nm and -30dBm at 1310nm across a broad 750nm–1700nm wavelength range. The low insertion loss of 1.0dB ensures live signals remain unharmed during non-destructive testing. Powered by 2 AA alkaline batteries delivering over 60 hours of continuous operation alongside an auto-off feature, it reliably supports long shifts in the field.
