Optical fibers are the core of almost all fast paced communication networks. These cables are the thin threads of glass or plastic bundles together in a cable. Fiber cables works on the principle of light. Instead of current, this guided transmission media rely on light beams that travel straight to carry data from one location to another at extremely high speed.
Threats to the speed of these high-speed optical fibers are contaminations like dirt particles, oils from hands, spotting, and damages like chips, spotting, scratches etc., that if not paid timely attention can halt or effect the entire network.
To ensure the interruption-free communications and avoid the situations like signal or light loss, periodic testing procedures need to be implemented. To execute testing on fiber cables different types of testing equipments are used that help finding the locations of faults, and the types of issues that let testing professionals to use appropriate algorithms to six those problems.
Multimeter is one among the types of fiber optic testing equipment available at fiberqa. Lets’ have a brief understanding about its parts and functionality:
Fiber optic multimeter is a handheld device that incorporates different tools of electronic testing and measurement into it. Both an optical light source and power meter are combined into this unit that helps to perform closed-loop testing on optical fibers. Each of these modules can also work individually. Technically, they are designed to perform variety of tests with just a single unit. This testing device is widely used in CATV, telecommunications, and to perform lab testing on fiber cables etc.
Key features of fiber optic multimeter are:
Multi-wavelength signal measurement
Variety of configurations settings
Stable light source
Power meter
Auto power off for long battery life
BASIC PARTS OF MULTIMETER:
Display: Multimeter is designed with a monochrome LCD digital screen to display the results of testing in numerical form with two or three decimal places. The device also has an icon to configure different types of settings (for examples Omega symbol for resistance). Sophisticated models of this device are designed with an oscilloscope function that display results both in numerical as well as graphical form.
Controls: Multimeter has various control points that allow users to select the settings for measurement such as voltage, resistance etc. Buttons and switches are also mounted on it for selecting range of values.
Probes: Probes are the metal needles that are touches to tracks, components, and wires on a printed circuit board that helps to take readings. They are designed with two colors: red for positive and black for negative.
Power source: For a hand held fiber optic multimeter, power source is typically a battery.
Fiber optic testing equipment plays a vital role to ensure the smooth functioning of wide range of communication networks.
