Do you have a question about the FirstFiber FF-980 REV and is the answer not in the manual?

This document describes the Optical Fiber Tester, a device designed for comprehensive testing and analysis of optical fiber networks.

Function Description

The Optical Fiber Tester is a multi-functional device capable of performing various tests on optical fiber, including Optical Power Meter (OPM), Visual Fault Locator (VFL), Light Source (LS), and RJ45 Sequence/Length/Tracker tests. It is designed to assist in the installation, maintenance, and troubleshooting of fiber optic communication systems.

Optical Power Meter (OPM) The OPM function measures the optical power of a fiber optic signal. It can display absolute power in dBm or relative power in dB. Key features include:

Wavelength Selection: Supports various wavelengths (850/1300/1310/1490/1550/1625nm) to match different fiber types and applications.
Absolute Power Measurement: Displays the current optical power in dBm.
Relative Power Measurement: Allows setting a reference power to measure loss or gain in dB.
Frequency Detection: Can detect modulated signals at 270Hz, 330Hz, 1KHz, and 2KHz.
Auto-off Function: Automatically powers off after a period of inactivity to conserve battery.
Backlight Adjustment: Allows adjusting the screen backlight for better visibility.

Visual Fault Locator (VFL) The VFL function uses a visible red laser to locate breaks, bends, and poor connections in optical fibers. It helps identify faults visually, making it easier to pinpoint problem areas.

Wavelength: Typically operates at 650nm.
Output Power: Available in different output powers (e.g., 10mW, 20mW, 30mW) to suit various fiber lengths and fault detection requirements.
Operating Modes: Supports continuous wave (CW) and modulated (2Hz) modes.
Safety Warning: Displays a "DANGER" warning when the VFL is active, reminding users not to look directly into the laser output.

Light Source (LS) The LS function provides a stable optical signal at various wavelengths for testing fiber optic cables. It is often used in conjunction with an OPM to measure insertion loss.

Wavelength Selection: Supports multiple wavelengths (e.g., 1310/1550nm, 850/1300nm) to match different fiber types.
Output Power: Provides stable output power.
Operating Modes: Supports continuous wave (CW) and modulated (270Hz, 330Hz, 1KHz, 2KHz) modes.
Fiber Type Compatibility: Can be used with both single-mode and multi-mode fibers depending on the selected wavelength.

RJ45 Sequence/Length/Tracker This function is designed for testing RJ45 network cables.

RJ45 Sequence Test: Checks the wiring sequence of RJ45 cables to ensure correct pin assignments. It can identify open circuits, short circuits, and cross-overs.
RJ45 Length Test: Measures the length of RJ45 cables.
RJ45 Tracker: Helps locate RJ45 cables in a bundle or wall by emitting an audible tone.

Important Technical Specifications

Display: LCD screen for displaying test results and menu navigation.
Power Supply: Rechargeable battery, typically charged via a standard AC adapter.
Interface: USB port for data transfer and possibly firmware updates.
Connectors: Universal optical connectors (e.g., FC/SC/ST interchangeable) for OPM, VFL, and LS functions. RJ45 port for network cable testing.
Operating Environment: Specified temperature and humidity ranges for optimal performance.
Storage Environment: Specified temperature and humidity ranges for safe storage.

Usage Features

User Interface:

Main Interface: Provides quick access to OPM, VFL, LS, and RJ45 functions.
Menu Navigation: Uses directional keys (up, down, left, right) and an "OK" key for menu selection and parameter adjustment.
Function Keys: Dedicated keys (F1-F4) for specific actions within each function, such as switching modes, saving data, or accessing settings.
Back Key: Returns to the previous menu or exits the current function.
On/Off Key: Powers the device on or off. A long press typically powers off, while a short press may turn on/off the backlight.

Data Management:

Event Log: Records important events such as power on/off, function changes, and system warnings.
File Save: Allows users to save test results for later review or analysis. Saved files can be managed (viewed, renamed, deleted) through the device's file operation menu.
Auto-Save Function: Can be configured to automatically save test results after each measurement or at specified intervals.
Data Export: Test results can be exported via USB to a computer for further analysis or reporting.

Settings:

System Settings: Allows configuration of various device parameters, including:
- Auto-off Time: Sets the duration of inactivity before the device automatically powers off.
- Backlight Brightness: Adjusts the screen backlight intensity.
- Language: Selects the operating language.
- Date and Time: Sets the system date and time.
- Calibration: Provides options for calibrating the OPM and LS functions to maintain accuracy.
- Factory Reset: Resets all settings to their default values.

Zoom Function:

Zoom In/Out: Allows zooming in on specific areas of the display, particularly useful for detailed viewing of test results or graphs.
Axis Zoom: Can zoom along the X or Y axis independently for more focused analysis.

Event Log:

The device maintains an event log that records various operational events, including:
- Power on/off
- Function changes
- Parameter modifications
- Calibration events
- Error messages
- File operations (save, delete)
- Battery status changes

Maintenance Features

Cleaning:

Optical Interface: The optical interface (fiber adapter) should be kept clean to ensure accurate measurements. Use a specialized fiber cleaning tool or lint-free wipes with alcohol to clean the optical port.
Screen: The LCD screen should be cleaned with a soft, dry cloth. Avoid using abrasive cleaners.
Device Body: The device body can be wiped with a soft, damp cloth.

Battery Management:

Charging: Charge the device using the provided AC adapter. Ensure the adapter is compatible with the device's power requirements.
Battery Life: Monitor the battery indicator on the screen. Recharge the battery when it is low to avoid interruptions during testing.
Storage: If the device is to be stored for an extended period, ensure the battery is partially charged (e.g., 50%) to prolong its lifespan. Avoid storing the device in extreme temperatures.

Calibration:

Regular Calibration: The OPM and LS functions may require periodic calibration to maintain measurement accuracy. Refer to the manual for calibration procedures or contact the manufacturer for service.
Self-Calibration: Some devices may offer a self-calibration option within the system settings.

Firmware Updates:

The device may support firmware updates to improve performance, add new features, or fix bugs. Check the manufacturer's website for available updates and follow the provided instructions for installation.

General Care:

Protection: Protect the device from physical shock, drops, and exposure to water or other liquids.
