VISIBLE LASER OPERATION
KI2000 UM-6

26 -
This is applicable to KI2800 and KI2601 Series instruments.
A visible laser is a useful low skill fault finding tool and is either PC or
APC connector-specific. This is determined when ordering the
instrument, and can only be changed at the factory.
In practice, due to the low precision of the connection, APC connectors
can usually be used with a VFL that has a PC connector.
CAUTION!
When working with PC/ APC mis-matched connectors, rough
connector handling can result in connector damage.
The visible laser works equally well in single mode and multimode
systems. Although red light is visible at the fiber end up to about 5km,
best performance will be achieved over distances of less than 1km.
If the laser light is inserted into a faulty system, the fault point will glow
red visible through most 3mm patch lead jackets. Please note this
should be tested before proceeding as some types of patch lead
jackets absorb light. It is also generally possible to locate faulty
connectors in the same way.
KI2601 Series:
To switch on the visible laser, press [On] then [SOURCE].
To improve visibility, the laser is modulated at 2Hz. To change
modulation frequency, press and release [Mode] while source is on.
VisiTester:
VisiTester is activated automatically when the relevant source port is
equipped with VFL: a visible light sequence is included in the test
sequence. When performing sequential loss testing it’s then obvious
where the light source has been plugged in. For fault finding the
combined red / infra red signal allows both VFL inspection and clip-on
fiber identifiers to be used with the same source hook-up, giving up to
200Km of fault finding range in the one hook-up.
The VisiTester laser can also be activated manually for simple fault
finding activities.
WARNING!
Although the visible laser, classified as Class 1, is eye safe, please
observe required optical safety measures.
