Visible fault identifier (VFI) is an economic and effective option in
detecting fiber fault position accurately. Because the red laser signal
could locate the accurate position occurring loss, for ray would flee out
from defective fiber. VIF also has wonderful performance in terminal-to-
terminal continuous test.

650nm laser system in DT-602 could increase short-distance visibility and
realize long-distance transferring, which makes it applicable for short-
distance and long-distance conditions.

Functions and features:
1) Locate faults of bare fiber, fiber connective line and ceramic core.
2) Trace fiber and locate faults position accurately.
3) It could overcome OTDR blind area thus makes a perfect supplement to
OTDR function.
4) With extreme bright 650nm red laser, it is much brighter than other
long wavelength fault locator.
5) Extreme penetrating power could penetrate and traverse fiber connective
line.
6) Two lighting modes: continuous and pulse lighting, pulse modulation
frequency: 2 ~ 3Hz
7) General FC connector and interface
8) 9V eliminative battery for power supply
9) Hi-output power: ?1mw
10) Fiber locating distance range: 5km
11) Compact, delicate and portable.
