Visual Fault Locator ( Remote Unit Style - VFL1 )

Remote Unit Style Visual Fault Locator VFL1This VFL1 injects 650nm visible laser light into the fiber. The red laser light scatters when the light encounters a break or sharp bend for both single mode and multi mode fibers. It can test bundled cables and breaks or bends in patch cords, pigtails, bare fibers, etc. which the OTDR cannot detect during their operation dead zone. It can be with FC connector, as well as can accept any optical connector style with a 2.5mm ferrule. With its low cost and high performance, this is one of your ideal choice for optical fiber solutions.

Features
  • Compact size and light weight.
  • Easily detects breaks, bad splices, tight crimp, micro bends and bad connection.
  • Suitable for both singlemode and multimode fiber patchcord.
  • 650nm lasing wavelength provides a good balance of visibility and transmission range.
  • Suitable for 2.5mm (FC, SC, ST) ferrule diameter connectors.
  • Locates fault up to 10Km in fiber

Visual Fault Locator ( Pen Style - VFL2)

Pen Style Visual Fault Locator VFL2This Universal Visual Fault Locator is streamline pencil styled that features a universal connector accepting any optical connector style with a 2.5mm ferrule and 1.25mm ferrule. The output is from a 650nm laser diode providing visibility to 6 Km ideally for both singlemode and multimode patchcord/cable plant inspection. Breaks, bad splices, tight crimps, faulty splice and bad connection can be identified by means of visible red laser emitting from the VFL.


Universal Visual Fault Locator

Two AAA size batteries (both Alkaline or rechargeable batteries) are used to keep the size and weight down. Low battery indicator is implemented to alert user when the battery capacity is low.

This VFL can be used to locate faults in patchcord with variety of connector types in both 2.5mm (such as FC, SC and ST) and 1.25mm (such as LC and MU) ferrule diameter.

Visual Fault Locator 1.25mm connector


Features

  • Small size and lightweight.
  • Find breaks, bad splices, tight crimp, faulty splice and bad connection.
  • Suitable for both singlemode and multimode fiber patchcord.
  • 650nm lasing wavelength provides a good balance of visibility and transmission range.
  • Suitable for 2.5mm (FC, SC, ST) and 1.25mm (LC) ferrule diameter connectors.
  • Laser driving mode in either Continuous or Pulse mode of 2.5Hz operation, with LED indicator.
  • Low battery indicator on status LED.
  • CE, RoHS certification.
