Competitive market pressures demand that networks are continuously upgraded and maintained to ensure the delivery of higher-speed, higher-quality applications and services to customers. The constant evolution of high-speed optical fiber systems raises the level of testing, accuracy, and precision required on the fiber infrastructure to support these applications and services.

Fiber testing is critical today for nearly every type of network. Proficiency is required by fiber optic installers, contractors, project managers, technicians and engineers that need to understand, apply, and correctly measure and record the performance of fiber infrastructures.

As these networks continue to expand and user load continues to increase, the development of standardized fiber testing practices becomes increasingly important. Over years ago, experiments demonstrated the ability of light to travel through a curved glass substrate and retain most of its original intensity.

These signals can be transmitted through long fiber optic runs to a receiver at the far end of the line, where the signal is converted back into its original binary form. This is the readable format for computer systems and devices. To verify and maintain the integrity of these optical signals throughout long distance runs and complex networks, and keep pace with the increases in bandwidth, fiber testing processes must continually evolve.

The application of fiber optic communication may seem elegant in its simplicity, but fiber optic cable testing requires an understanding of some basic principles that differentiate fiber testing from its analog wire testing predecessor. An optical fiber is composed of a very thin glass rod, which is surrounded by a plastic protective coating.

Light, which is injected into the core of the glass fiber, will follow the physical path of that fiber due to the total internal reflection of the light between the core and the cladding. Fiber is classified into different types multimode or singlemode based on the way in which the light travels through it. The fiber type is closely related to the diameter of the core and cladding. The primary advantages of multimode fiber are the ease of coupling to light sources and to other fiber, lower cost light sources transmitters , and simplified connectorization and splicing processes.

However, its relatively high attenuation optic loss and low bandwidth limit the transmission of light over multimode fiber to short distances. The advantage of singlemode fiber is its higher performance with respect to bandwidth and attenuation. The small core size of singlemode fiber generally requires more expensive transmitters and alignment systems to achieve efficient coupling. Nonetheless, for high performance systems or for systems that are more than a few kilometers in length, singlemode fiber remains the best solution.

In order to assess the quality of a fiber installation, to sign it off as ready for service activation and to ensure reliable on-going operation of a fiber link you must perform some fiber test. When two fibers are mated together, a key requirement is to ensure light passes from fiber to fiber without excessive loss or back reflections.

What remains challenging is maintaining a pristine end face. A single particle mated into the core of a fiber can cause significant insertion loss, back reflection, and even equipment damage. Proactive fiber inspection is essential to ensure reliable fiber connections.

When testing fiber networks, a visible laser source connected to one end of the cable can be used to verify the transmission to the opposite end. This type of fiber test is only intended to detect gross fiber defects such as macrobends. Fiber continuity testing can also be used to determine whether the right fiber optic cable is connected to the right patch panel location.

A Visual fault locator VFL uses visible spectrum laser light to test fiber continuity as well as detecting fault conditions. The red light source will be visible through the coating at the location of any fiber breaks or defective splices. As the light source traverses the fiber, it decreases in power level. The decrease in power level also called optical loss is expressed in Decibels dB.

The most accurate way to measure the overall optical loss in a fiber is to inject a known level of light in one end and measure the level of light at the other end. This measurement done with an optical light source and power meter requires access to both ends of the fiber. A power measurement is a test of the signal strength from the transmitter once a system is live or activated.

A power meter at the opposite end of the circuit will measure the light source with and without the fiber under test to quantify the loss in dB of the fiber itself. This method is the standard test for loss in an installed cable plant, and includes the loss measurements at both test cable connection ends.

For this reason, ensuring all connections are extremely clean is an important aspect of any fiber test. Utilizing high intensity laser light emitted at a pre-defined pulse interval through a connecting cable at one end of the fiber optic cable run, the OTDR instrument analyzes the backscatter of light returning to the source location. This one-ended fiber test method can be used to quantitatively analyze the loss, as well as pinpointing the loss locations.

Testing fiber optic networks is an essential part of fiber optic installation, as well as ongoing maintenance. Following some fundamental fiber testing best practices will lead to safer, more efficient, and more reliable fiber deployments and network activation.
