The VLF-275 is a hand-held battery powered stabilised
fibre optic laser source that emits visible (red) light at 650 nm.
Its intended function is to allow an operator to
identify the exact location of a break, microbend, or other discontinuity in a
fibre optic cable. As the radiation is visible, light emanating from a break or
microbend enables the user to locate the exact position of a fault even at very
short distances that would not be detectable by conventional means such as an
Optical Time-Domain Reflectometer, (OTDR). It is also useful for identifying a
particular fibre in a cable by exciting the fibre to be located with visible
radiation. It has provision for coupling the laser output to a connectorised
fibre.
