Visual Fault Locator

Visual fault locator (also called laser fault locator or 650nm fault locator) is a handheld device using 650nm or 635nm visible laser source that emits a bright beam of laser light into a fiber, allowing the user to visually detect a fiber fault for up to 5 km.

With these fault locators you can easily isolate high losses and faults in optical fiber cables. The bright beam of 650nm or 635nm red light in a fiber allows you to see a break as a glowing or blinking red light. Two versions are available: one with a universal port for 2.5mm ferrule connectors (FC, SC, ST, E2000, DIN), and one which includes an adapter that allows use with 1.25mm ferrule connectors as well (LC, MU).

Features of FOFS's line of Visual Fault Locator(Laser Fault Locator):

• Both CW and pulsed mode are available
• Lightweight (handheld and pen shape available)
• long continuous operation time
• Cost effective solution

Laser Fault Locators provide the capability to trace fiber routes for end-to-end continuity. Locate breaks within the deadzone of an OTDR, bad splices, potential fiber problems caused by imperfections as well as microbends and macrobends. These devices also can be used as fiber identifiers. They can operate on multimode or singlemode fibers independent of the transmission wavelength. Visible beams make results easily noticeable. Laser fault locators are excellent instruments for locating fiber faults and other anomalies where the pulse width of the laser used in OTDRs won't allow measurements to be made. Applications include LAN, WAN, fiber data links, telephone and CATV.

A 650nm fault locator is used for cable fault detection over short to moderate distances.

These visual fault finders use the more effective 635 nm wavelength. They comply with the safety requirements for Class 1 or 2 laser devices.
