Section 1. Introduction

Tempo’s 930XC handheld OTDRs can make an assessment of one single optical ber or a whole optical ber chain. In addition,

the user can directly observe loss and events distribution of an optical ber chain.

The 930XC tools check the transmission quality of optical ber through the measurement of backscatter. Standard

organizations like the International Telecom Union (ITU) dene backscatter as an effective analysis means to measure optical

ber loss. Backscattering is also the only effective way of connector inspection, which can be applied to measure the length of

optical ber.

The 930XC OTDRs operate by reviewing events in optical ber (for example, irregularities and connectors). These tools can

help identify irregularities in optical ber, locate them, and measure their attenuation, relevant loss, and homogeneity.

These tools are easy-to-use, small, and compact with large LCD displays and graphical interfaces. They can save and transfer

the measurement curves data to a PC by using the provided Trace Viewer software for further analyzing, reporting, and

printing.

Basic applications:

• Measure the length of optical ber and cable.

• Measure the distance between two points on optical ber and cable.

• Locate faults and ruptures of optical ber and cable.

• Display distribution curve of optical ber and cable loss.

• Measure attenuation coefcient of optical ber and cable.

• Measure loss between two points on optical ber and cable.

• Measure loss of tie-ins.

• Measure reection of reection events of optical ber and cable.

• The 930XC-30F can measure live optical bers at 1625 nm.

For a specic event (transmission quality changed due to faults caused by fusion splicing, connector, bending, etc.), the

following measurements can be carried out:

• For each event: Distance, loss, and reection.

• For each section of optical ber: Length and loss of dB or dB/unit length.

• For the whole optical ber chain: Length and loss of dB.

Additional features:

• Large LCD display with auto or manual adjustment of contrast.

• Backlight LCD display supports night operation.

• Easy operation with trace graphic display.

• Trace storage function.

• RS-232 and USB data upload ports.

• Trace Viewer software for analyzing and reporting previously stored data.

• Auto off function to conserve battery life.

• DC/AC power supply.

• Macrobend analysis.

• Link Viewer for automated Pass/Fail analysis.
