Basics about an Optical Time-Domain Reflectometer

What is an OTDR? An Optical Time-Domain Reflectometer (OTDR) is a device that uses light pulses to measure the properties of an optical fiber. It sends light pulses into one end of the fiber and detects the light that is backscattered along the fiber. It then calculates the intensity and timing of the returned light…

Types of OSP cables

Outside plant cable designs are tailored to the specific application. In OSP installations, cables may be underground, direct buried, aerial or submarine. Underground Cable Conduit and innerducts are generally used for installation of underground cables. These OSP cables are made to withstand high rated values of tensile strength, and may need lubricants to help reduce…

Fiber connectors and polish types

The different polish types of fiber connectors affect the optical return loss (ORL) of the connector. ORL is the amount of light that is reflected back to the source when it strikes the end face of the connector. A lower ORL means that less light is reflected back, which results in a lower signal loss.…

Fiber Optic Cable Flame Resistant Levels

Fiber optic cables are used in a wide variety of applications, including telecommunications, data networking, and security systems. In some of these applications, it is important for the cables to be flame resistant. This is because a fire can cause significant damage to a building and its occupants, and flame resistant cables can help to…

Fusion splice vs. Mechanical splice

Fusion Splicing vs. Mechanical Splicing Fiber optic splicing is the process of joining two optical fibers together. There are two main types of fiber optic splicing: fusion splicing and mechanical splicing. Fusion Splicing Fusion splicing is the most common type of fiber optic splicing. In fusion splicing, the two fibers are joined by melting them…
