The LFI120 Live Fiber Identifier is an essential tool for fiber maintenance. It can be used for testing both singlemode and multimode
fiber in a variety of places. The straightforward easy pull trigger operation ensures the job can be done quickly, and an audible
warning helps identify both trac direction and frequency ton, from 270Hz to 2KHz.
Sunshade
Protects the fiber optic cable and measurement from ambient
light interference.
Interchangeable Adapter Heads
Easily switch to one of four included adapter heads for
dierent size fiber.
Screen
The LFI120 screen indicates the Relative Core Power, Battery
Level, and Trac Direction.
Fiber Clamp
Easily slide the clamp upwards until it clicks into place, holding
the fiber firm in the housing.
Battery Cover
Houses one 9V Alkaline battery

Read and understand all of the instructions and safety information in this manual
before operating this tool.
Laser/LED Hazard
Avoid eye exposure to open fiber connectors and interfaces when working with fiber
systems. They may be connected to a live laser source.
Do not look into the output port of a Laser or LED source.
Point fiber endfaces toward non-reflective surfaces to prevent reflection of laser.
Electric Shock Hazard
Pay attention to proper battery polarity. Do not mix battery types or manufacturers.
Do not open the unit with the exception of the battery compartment door.
Use this unit only for its intended purpose as outlined in this document.
Damage to Item Hazard
Do not leave item in direct sunlight or near heat sources, submerge in water, or subject
unit to strong impact.
Cover the fiber interface with the flip-cap when not in use.
Do not throw this product away
Contact your local recycling station to dispose of properly.

1. Insert the fiber into the adapter head, push the clamp upwards to lock it into place and cover with sunshade
2. When the optical signal passed through the fiber, the LED display will illuminate with the relative fiber core power in a digital
format. The arrow indicators will illuminate to indicate the trac direction if any trac is detected. If there is a modulation tone
present, the LFI120 will indicate the tone detected on the display and make an audible beep.
3. If not optical signal is detected in the fiber, the LED display will display “L0” to indicate that no relative core power was detected.

Features
• Easy pull trigger operation for simple, no-fuss use
• Audible warning for frequency tone with on-screen indicator
• 3mm, 2mm, 900um, and 250um/200um adapters included
• Sunshade to protect fiber optic cable from ambient light interference
• LED battery indicator
• Live, in-line testing without interruption of live trac
• Identifies present modulation tones, 270Hz, 1KHz, 2KHz
• Low Power Consumption with automatic shut-o
• Mechanical damping design ensures no damage to the fiber
• Strong and durable metal design with carry pouch
Notes
Audible Alerts
The LFI120 emits a continuous audible beep when a modulating signal is detected. If a tone is present, the display will also indicate
the tone that is being detected.
Auto O
The LFI120 turns o automatically if the clamp is not engaged. This is to save battery life.
Maintenance
Low Battery
The LFI120 provides the capability to perform over 100 tests under normal use conditions. If the devices battery becomes low,
the battery level indicator on the screen will show as low, or the device may not turn on. If this happens, the 9V battery should be
replaced with a high quality 9V replacement battery.
Optical Connector Detectors
The LFI120 is equipped with two optical detectors designed for reading the relative core power of the fiber and determining the
trac direction. It is imperative that these optical components should be kept covered and protected from contamination when
not in use. A microfiber cloth or canned air may be used to remove large contaminant or dust that may become lodged near the
detectors. Care must be taken to avoid objects that may damage the glass surface of the optical sensors. If visible scratches or
cracks are observed on either detector, or if the device is no longer reading properly, please contact Ripley Tools for proper repair
and potential re-calibration.
