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.

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 donthaveto. 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. Advance d wave-shape analysis software finds more events than other OTDRs can locate. All these features combine to give you more informati on 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.
CAUTION. The platform and modules contain static sensitive devices. Do not touch the connector pins.
1. Power off the NetTek Analyzer Platform: select Start >
Shutdown.
2. Disconnect all cables to the NetTek Analyzer Platform and
instrument modules.

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 t est 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.
Getting Started
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 el ements, slide the connector adapter onto the laser output port, and turn clockwise until the connector adapter is finger tight (see Figure 1--4).
