Fiber OneShot PRO in fibre optic toolkit fills the gap between a VFL and an OTDR. These optical inspection systems have the simplicity of a VFL, and provide distance and power information on high losses, breaks, and the end of the fibre. They also identify live fibre making them perfect for fibre cable troubleshooting.

  • Works on single mode fibre, 9/125µm
  • 1550nm output wavelength. Compatible with standard PON wavelengths: 1310, 1490, 1550 and 1625nm
  • Measure up to 75,459 feet (23,000 metres) of fibre in seconds
  • Locate severe bends, high-loss splices, breaks and dirty connectors in singlemode fibre
  • Measure and locate high loss connections and breaks
  • Locate the end of a fibre
  • Find potential sources of high bit error rates caused by reflectance from dirty or poor connections
  • Detects live optical signals before it begins testing
  • Quick set-up. Connect your fibre and press the Test button. No lengthy set-up necessary
  • Find problems quickly. Six-second test time—no more blind troubleshooting that can waste hours
  • Change the Index of Refraction (IOR) to improve fibre length accuracy
  • Visible in dark areas. Backlighted display turns off automatically
  • Removable SC adapter is easily cleaned
  • Optional LC, ST and FT interchangeable adapters are available
  • Long battery life, 1,500 tests (typical) from 2 AA alkaline batteries
  • Rugged construction; vibration and drop tested to 1 meter

Live fibre detection

Detects optical signals from 1250nm to 1625nm and shows ACTIVE LINE if a signal is there.

Looks for a signal every 3 seconds after the first detection. +7 dB maximum input power.

1  ± user-configurable Index of Refraction (IOR) error ± the incident location error.

2  ± user-configurable Index of Refraction (IOR) error ± the incident location error.

3  Detects the location of an incident that has a reflectance larger than -62 dB. Detects incidents >2 m after the bulkhead connector when the bulkhead reflectance is <35 dB. Detects incidents >3 m after an incident when the incident reflectance is <35 dB.

4  Detects incidents >10 m after the bulkhead connector or any prior incident when the bulkhead reflectance is <-35 dB and the reflectance of any prior incident is  <-35 dB. The maximum link loss prior to the incident is <7 dB.
