Multifunctional optical power meter with VFL

The CableMaster-FO is a multifunctional optical power meter and integrates the functions of a visual fault locator for port/polarity detection (VFL/red light), an attenuation meter for determining the attenuation of the fibre optic signal in dB, a power meter for determining the signal strength in dBm/mW, a copper patch cord tester and a torch.


Areas of application
  • Verification of FTTx broadband installations
  • Simple attenuation determination on fibre optic cabling to ensure the attenuation budget is met
  • Visual Fault Locator (VFL) for correct polarity of the fibre link and checking for interruptions
  • Optical power meter mode for measuring the power at different fibre optic interfaces
Special characteristics
  • Particularly small, reliable and robust
  • Storage of 50 measurement results and more
  • VFL, torch and patch cord test integrated
  • OPM, attenuation/power display (dBm, dB, mW)
  • Rechargeable battery for operating times of up to 80 hours
Your benefit
  • Best price/performance ratio on the market
  • Many functions combined in a very small unit
  • Simple, intuitive operation - ready for immediate use
  • Everything included (battery, charging cable, adapter 2.5/1.25mm)
