ShinewayTech OFI-20A Optical Fiber Identifier


OFI-20A can detect optical signal presence, type and direction anywhere on fibers during optical network deployment, maintenance and troubleshooting. With non-destructive macro-bend detection technology, it introduces no damage to tested fiber or interference to the service on fiber. OFI-20A is able to identify wide-spectrum signals (such as signals in CATV system) and can be used in SONET/SDH & DWDM systems tests.


  • Fiber types: 250µm, 900µm, 2mm/3mm jacketed fiber
  • Non-destructive detection

OFI–50A uses optical fiber sensing principle to confirm the target fiber; It can quickly identify deep buried, overhead and pipe fiber cable without any destroy, and provide a simple method for maintenance personnel. Users only need gently knock on cable, when knocking to the target cable, OFI-50 can clearly hear the knock from earphone, which can accurately identify the target cable. OFI–50A is real one-key type test; handheld design, easy to carry, 3.5' color screen real-time waveform; the software of the intelligent struck the judgment of the two operation / display mode, combined with the Headset real-time audio, with 3 kinds of recognition percussion method, so as to quickly and accurately identify the measured cable. OFI-50A is a kind of ideal tool for optical fiber

PDF Datasheet


The KI 6354 visual fault locator is a small, high quality and very low skill fiber cable tester. It has only one button, and an operating range of a few km. Visible light is injected into the fiber under test, and can be seen from a fiber end, or through most 3 mm cable types at a break or loss point. Unusually, this pen meets Class 1 safety standards (IEC IEC60825 2011) for total emitted power when no fiber is connected, so does not need any special safety eye safety precautions under any condition.


  • Very simple and compact
  • 2 x AAA alkaline batteries
  • Captive dust cap
  • Pen-style retaining clip
  • Recessed button
  • 2.5 mm universal connector
  • Selectable Pulsed / CW
  • Class 1 eye safety, 2011 IEC standards
  • Needs no special eye safety procedures
  • Durable construction
  • 3 years warranty
