When testing loss in a fiber optic link, some basic principles must be kept in mind all the time 1

What is WDM WDM is the abbreviation for Wavelength Division Multiplexing

Overview of Fiber Optic Testing There are mandatory tests for every stage of the design, manufacture, and installation of the fiber optic components, link, cable plant, and network Most fiber optic test procedures have been thoroughly tested and codified as industry standards

The standards for ATM were first developed in the mid 1980s The goal was to design a single networking strategy that could transport real-time video and audio as well as image files, text and email

The SONET standards were developed in the mid-1980s to take advantage of low-cost transmission over optical fibers It defines a hierarchy of data rates, formats for framing and multiplexing the payload data, as well as optical signal specifications(wavelength and dispersion), allowing multi-vendor interoperability

There is no question that fiber optic communication is our future Fiber optic communication industry has been enjoying amazing growth for over 15 years

How Does an OTDR Work In fiber optic networks, OTDR (Optical Time Domain Reflectometer) is an opto-electronic instrument used to characterize an optical fiber

What is optical fiber fusion splicing Optical fiber fusion splicing is a welded joint formed between two optical fibers

Fiber optic cables are exposed to electrical, mechanical, chemical and environmental elements, so proper installation is critical for the long-term stability and survival of fiber cables Cable installation must also meet the NEC(National Electric Code) and local building codes

Understanding The Basic Terms 1 Dead end pole: Dead end pole is a utility pole on which self-supporting figure 8 aerial cable or a steel messenger is tensioned and terminated into a dead-end fixture
