You can find many fiber optic equipment to test different major manufacturers such as fluke, Noyes, JDSU and many other providers. I will cover the most likely encounter in general service, installation and operation.

The tasks of the basic fiber optic test and measurement include optical power measurement, the measurement of insertion loss (attenuation), wavelength measurement and measurement of signal quality, even. Some computers will display the results while others would have to conclude that his trial based on the raw data they present.

:: GRP Optical Power Meters

Fiber optic power meters measure optical power, which can be deduced from its name. They are composed of a fiber optic adapter, a silicon or germanium detector, the signal amplifier circuit and a digital display.

power meters are of two factors: desktop and portable handheld. In the field of service and installation, you use a type of handheld security. They can display the optical power measured in two units: watts or decibels. They must be calibrated for accurate measurement.

The most popular power meters are calibrated to 850 nm, 1310 and 1550, the three bands wavelength for the main fiber optic communications.

You have to configure its wavelength before taking the actual test. This is very important, because otherwise you get a completely fucked to a different wavelength.

:: Fiber Optic Light Source Power Measurement

Power meters are useless without a source of light. A variety of light sources are available for different applications and must have the correct source for measurement. Light source can range from several hundred dollars to tens of thousands of dollars depending on your testing requirements.

Light source can be divided into several groups main. These are the main types in the market.

1. Light Sources Broadband

broadband source of light emits a wide range of lengths wave. Typical sources include tungsten lamps, LEDs and ASE (Amplified Spontaneous Emission) sources. They typically cover hundreds of nanometers.

light sources are broadband widely used in the laboratory and manufacturing floors for the analysis of the performance spectrum and not often used in field service.

2. LED sources

LEDs are widely used in field service as a light source for measurement of energy, such as 850nm and 1300nm multimode. LEDs emit a series typical wavelength of 50 nm covering up to 100 nm.

3. stationary sources laser diode wavelength

Fixed-length laser diodes wave are widely used in field service. Typical applications include single mode 1310 and 1550 single-mode systems.

:: Discuss Fiber Optic Fixed

Optical fiber talk sets are specially designed for installers working on a long fiber link two points. Installers can be used to communicate and coordinate their work.

Basically what we talk about fiber does is to turn all any of the fiber links in a channel communication or telephone connection. It includes a transmitter and a receiver to send and receive voice signal through the fiber. Most fiber systems optics have talk headset.

:: Laser Visual Fault Locators

Basically laser visual fault locators are red source of low cost color laser that emits a red laser light ranging from 630 nm to 670 nm. When injected the red laser light in the fiber, you can see the light escaping breakpoints, defective joints, macrobending and other installation errors.

Laser visual fault locators emit much more power than the continuity fiber testers that use an LED light source in red. So be careful to distinguish between these two teams.
