Fiber Optic Test Equipment Visual Fault Locators Used in Fiber Optic Cable Testing
General information
Fiber Visual fault locators (VFL) are used for installation, fault finding, continuity checking, polarity checking, verifying a signal path, and identifying a fiber. For single mode, multimode and plastic fibers.
Pen-based visual fault locator, which use 650nm semiconductor laser as a light emitting device, through the constant current drive, transmit the red light which power is stable. After connecting with optical interface, the red light can enter into the multimode and single mode fiber, achieve detecting function of optical fiber fault. It is an indispensable tool for fiber-optic construction, fiber-optic network maintenance, optical device production and research.
