## Summary description

KOMSHINE KFI-45 is a handheld optical fiber identifier combining non‑intrusive fiber identification, a visible fault locator (VFL) and an optical power meter (OPM). It detects signal presence and direction, locates breaks or faults with red laser tracing, and measures optical power levels for testing and maintenance of single‑mode networks in field diagnostics and installation tasks.

## Long description

The KOMSHINE KFI-45 is a handheld optical fiber identifier that combines non‑intrusive fiber identification, a visible fault locator (VFL) and an optical power meter (OPM). Designed for field diagnostics and installation of single‑mode networks, this compact instrument detects the presence and direction of optical signals without disconnecting the fiber, traces faults and breaks using a visible red laser, and measures optical power levels for verification and maintenance tasks.
Advantages
The device integrates three functions—identifier, VFL and OPM—into a single portable unit, reducing the number of tools technicians need to carry. Non‑intrusive detection preserves link integrity while allowing quick verification of live signals and their direction. The built‑in visible fault locator helps localize connectors, bends and breaks by injecting a red laser for visual tracing, and the optical power meter provides quantitative measurements for testing attenuation and signal levels. Its handheld form factor and straightforward controls support efficient on‑site troubleshooting and installation verification.
Suitable for
 Field technicians performing installation and acceptance tests on single‑mode fiber links
 Maintenance crews locating faults, breaks, bends or bad connectors in fiber runs
 Rapid verification of live signal presence and direction without service interruption
 Basic optical power measurements and loss checks during commissioning and troubleshooting
When it may not be suitable
The KFI-45 is intended for single‑mode fiber networks and for tasks that require non‑intrusive identification, visible fault tracing and basic power measurements. It is not designed for detailed OTDR-style distance fault locating or for multi‑mode fiber networks where different launch and detection methods are required. For precision laboratory measurements or extended wavelength ranges beyond the instrument's supported wavelengths, a dedicated lab-grade power meter or OTDR would be more appropriate.
Key specifications
 Functions: non‑intrusive fiber identifier, visible fault locator (red laser), optical power meter
 Targeted fiber type: single‑mode fiber
 Detection capability: presence and direction of optical signals on live fibers
 VFL: visible red laser for tracing and localizing faults and breaks
 OPM: measures optical power levels for basic attenuation and signal checks
 Form factor: handheld, portable unit suitable for field use
How to use
Connect the appropriate fiber interface or use the non‑intrusive clamp/contact method provided by the instrument to detect a live optical signal without disconnecting the fiber. Use the identifier mode to verify signal presence and direction. Activate the VFL to inject a visible red laser when tracing a suspected break or fault; follow the visible light emission at exposed points, connectors or along the jacket for localization. Switch to the OPM function to measure optical power levels at accessible connection points for verification of link loss and performance. Operate controls according to labeled functions and observe safety precautions when using laser output.
What to consider before purchase
 Confirm that your work is primarily on single‑mode fibers and that non‑intrusive identification meets your workflow needs
 Check the supported wavelength(s) and measurement range of the optical power meter to ensure compatibility with the signals you will test
 Consider whether you need OTDR-style distance measurements or multi‑mode support—if so, a different instrument may be required
Usage recommendations
When using the KOMSHINE KFI-45, always follow safe laser handling practices: never look directly into the laser output, avoid pointing the VFL at people, and use proper PPE where required. For troubleshooting, start with non‑intrusive identification to confirm live signals, then use the VFL to localize visible faults and the OPM to quantify power levels—this sequence helps preserve link integrity while delivering actionable diagnostics.
