1 APPLICATION
1.1 The Multifunctional optical measuring device (hereinafter referred to as
KI 6700) can perform the functions of the following devices used for
measuring optical fibers and fiber optic component characteristics:
−OTDR.
−Laser Light Source.
−Optical Power Meter – Option.
−Visual Fault Locator - Option.
As an OTDR the KI 6700 is designed for measuring attenuation in optical
fibers and their connections; optical fiber length and distance to the events.
When configured for SMF operation, the KI6700 can be used as a laser light
source
When optioned as an Optical Power Meter the KI 6700 can be used for
measuring optical power.
When optioned with a Visual Fault Locator (VFL) the KI 6700 can be used
for patch cord tracing and detection of fibre breaks in bare fibre, 900 µm and
patchcord.
1.2 KI 6700 can be used in the production of optical fibers and fiber-optic
cables as well as mounting and maintenance of fiber-optic communication
lines, for checking their condition and locating faults in them. The KI 6700
devices can work in laboratory and field environments being fed from the
external power source as well as autonomously.
1.3 Conditions for KI 6700 use:
−ambient temperature – from -10°Сto 50°С;
−relative humidity – not more than 90% at 25°С;
−atmospheric pressure - from 70 to 106,7 кPа.
