Getting Started

Getting Started

Before using the NetTek Analyzer Platform for the first time, refer to
the platform user manual for information on getting started,
including the following:

H Battery and power source information. (You must charge the

batteries before you can operate the NetTek Analyzer Platform
from internal battery power.)

H Calibrating the touch screen.

H Installing the tilt stand, shoulder strap, or strand hook.

Product Description

An optical time domain reflectometer (OTDR) measures and locates
fiber characteristics by transmitting light pulses into a fiber and
measuring the elapsed time and the amplitude of the received
reflection. The OTDR measures the distance to an event by
measuring the amount of time required to receive the reflection.

With this OTDR, you can:

H Document and verify installations of new fibers in a network.

H Locate faults in the fiber.

H Check bandwidth upgrade capability by measuring the return loss

and end-to-end loss in the network.

H Perform general preventive maintenance.

NetTek Analyzer OTDR Modules User Manual

1- 1

Getting Started

The NetTek Analyzer OTDR, with its easy-to-use interface, gives
you good results with minimal training. The IntelliTrace Plus test
mode automatically optimizes test parameters so you don’t have to.
It gives you the best resolution on every section of the fiber while
maximizing dynamic range. The NetTek Analyzer OTDR provides
an IntelliTrace Plus multi-pulsewidth, single-result auto test function
to significantly reduce dead zone effects on your tests. You can see
close events, including the first connector, at the same time you see
events 200 km away. Advanced wave-shape analysis software finds
more events than other OTDRs can locate. All these features
combine to give you more information on your cables, with precise
accuracy.

Installing an Instrument Module

Use the following procedure to install an instrument module onto the
rear of the NetTek Analyzer Platform or to attach one module onto
another. Refer to Figure 1--2 throughout this procedure.

Using the Laser Optical Port and Connector Adapter

WARNING. The light emitted by the laser source is invisible to the
human eye. Do not stare directly into the laser source. Doing so
while the laser is on can damage your eye.

Do not stare at the free end of a test fiber (the end not connected to
the instrument). If possible, direct the free end toward a non-reflec­tive surface.

CAUTION. Do not touch the exposed end of the laser output port with
anything but the proper cleaning materials. To maintain the
performance of fiber optic connectors, clean them every time you use
them. Refer to Cleaning beginning on page C--1.

To protect against dust and damage, cover the optical port when not
in use.

The OTDR tests optical fibers by emitting short pulses of laser light.
Figure 1--3 shows the location of the OTDR optical port. The optical
port snaps out to a 45% angle. To return the optical port to the closed
position, lift the release lever.

Install the Appropriate Connector Adapter

CAUTION. To avoid damage to the instrument, never connect a bare
fiber adapter directly to the instrument.

The connector adapter attaches the fiber to the laser optical port.
Connector adapters are packaged separately with new instruments,
and must be installed on the laser optical port before use.

The connector adapter on the OTDR must match the connector on
the test fiber. See page B--1 for a list of connector adapter options.

Connector adapters are keyed for proper mating with the laser output
port.

To install a connector adapter, align the keyed elements, slide the
connector adapter onto the laser output port, and turn clockwise until
the connector adapter is finger tight (see Figure 1--4).
