Fiber Characterization – Training Workshop

Can you accurately determine fault locations with your OTDR?
How do you accurately measure CD and PMD?
Do you know if your fiber cable support 10G traffic?
Can your fiber cable network support DWDM or CWDM systems?
Do you know how to identify high loss connectors and splices?

Our Fiber Characterization training will guide you to the answer of these questions and more. Let us provide you with a direction in assessing your fiber cable characteristics. We will show you how to verify the integrity and capacity of your fiber network by performing specific measurements of fiber parameters such as optical loss, chromatic dispersion, polarization mode dispersion and fiber reflections. We check for fiber anomalies and identify loss problems with our OTDR traces.

At the end of this workshop, you will be able to produce reports to substantiate your findings concluded through analysis of raw date.

Topics covered include the following:

OTDR Setup and Calibration

Not sure why your expensive OTDR cannot provide you with accurate cable fault locations? It can be due to incorrect index of refraction (IOR) and Helix Factor values that are entered into the OTDR. We show you how to determine proper values for IOR and Helix factor so that your next OTDR fault location measurement is accurate. Best and most accurate measurements of IOR and Helix factors are made during or prior fiber cable deployment construction. Post construction measurements are also possible but with less accuracy.

OTDR Measurements

otdr_small The Optical Time Domain Reflectometer (OTDR) is used to obtain a visual representation of an optical fiber's attenuation characteristics along its length. OTDR trace results include fiber attenuation, fiber loss, splice loss, splice location, connector loss, connector location, fiber length, bad fiber bend locations, other fiber anomaly locations and optical return loss (event reflections) which are graphically represented and charted in our report. We show you how to properly setup  and operate an OTDR, and read OTDR traces.  

Chromatic Dispersion Measurements

cd_smallChromatic dispersion (CD) limits the maximum transmission rate and distance capability of the fiber. If you are planning to increase your transmission rate to 1 Gbps or higher over long distances this report is suggested. We show you how to setup, operate chromatic dispersion test set and interpret test set results.

Polarization Mode Dispersion Measurements

pmd_smallPolarization Mode Dispersion (PMD) can affect transmission at rates of 10 Gbps and higher. There is no easy way to compensate for high PMD so knowing fiber PMD is important for 10G and higher systems. We show you how to setup, operate PMD test set and interpret test set results.

Optical Return Loss (ORL) Measurements

orl_small Optical Return Loss (ORL) measures the optical back reflection of a fiber caused by connectors, splices, other fiber anomalies and the fiber itself. High ORL can affect laser stability and increase transmission bit errors. Measurements are conducted at 1310nm and 1550nm.

Optical Power Meter and Attenuation Profile Measurements

How to measure fiber loss from 1270nm to 1620nm for. Full fiber attenuation profile .

Fiber Signal Latency Measurement

Latency How to measure network fiber latency and provide a tabulated results for all fibers. Signal propagation through fiber is slower than through air or copper. Therefore the added signal delay due to fiber latency is an important consideration for many time sensitive applications and protocols.

Visual Inspection of Network Fiber Connectors

Connectorface How to inspect and record connector cleanliness.
Attendees: This course is designed for fiber optic technicians, engineers, and managers that already have of a basic knowledge and hands on experience with fiber optic systems. It will provide the students with advanced and detailed information on how to properly measure optical fiber characteristics using the OTDR, CD test set, PMD test set, ORL test set, power meter, and laser source equipment.
