GAOTek Fiber Identifiers

GAOTek fiber identifiers is users to find specific optical fibers in optical fiber maintenance.




GAOTek fiber identifiers is users to find specific optical fibers in optical fiber maintenance. Fiber identifier is an essential tool for fiber maintenance to recognize specific fiber without disruption or damage. It can be used for identification anywhere on single-mode and multi-mode fibers. During maintenance, installation, cabling and restoration, it is often necessary to find and separate a specific fiber without interrupting business, by injecting a 1310 nm or 1550 nm signal with modulated tones (270 kHz, 1 kHz, 2 kHz) at one end.



  • Low frequency signal online injection
  • Do not interfere with the online optical fiber
  • Support a variety of optical fiber diameter
  • Identify the signal automatically
