FOA Certification: Testing and Restoration

Front

Why is testing important in fiber optic installation?

Back

To confirm proper installation, avoid issues later, and ensure customer approval and payment.

Front

When should fiber be tested during a project?

Back

Before installation (continuity), during (each segment), and after (end-to-end loss).

Front

What tools are used for basic continuity testing?

Back

A VFL (Visual Fault Locator) or fiber tracer.

Front

What does OLTS stand for and what does it do?

Back

Optical Loss Test Set – it measures insertion loss using a light source and power meter.

Front

When is OTDR used?

Back

Mainly for outside plant cables to check splice quality or troubleshoot faults.

Front

Why is polarity important in fiber links?

Back

Because each link uses two fibers; Tx (transmit) must connect to Rx (receive).

Front

What should a test plan include?

Back

Testing procedures, standards, reference method (1, 2, or 3 cables), and expected results.

Front

What makes OTDR less ideal for short premises cables?

Back

Short runs and reflectance from many connections confuse the OTDR trace.

Front

What are three special tests for long outside plant cables?

Back

Spectral Attenuation, Chromatic Dispersion (CD), and Polarization Mode Dispersion (PMD).

Front

What is the purpose of a restoration plan?

Back

To restore service quickly if a fiber cable is damaged.
