How to Design a High Performance Optical Receiver?
The structure of an optical receiver is simple: consisting of just a photodiode to produce the electrical current and an amplifier. But do not be fooled: it is far more complex to design a really high performance optical receiver. So we will talk about some of the criteria of actual... Read

How to Design a Highly Reliable Fiber Optic Network
What happens if a major fiber optic cable is cut or a major hubbing location is destroyed in a fiber network? Will the whole system be brought down? That is the subject of this article: the survivability of a well designed fiber network. Modern fiber optic transmission systems have provided tremendous capacity... Read

The Secrets of Choosing Ribbon Fiber
Do you know why it is so expensive to install Fiber To The Home? Why Bell companies are reluctant to deploy fiber optic network directly to consumers in a large scale? It's not the material cost. It's the labor! The introduction of fiber into the subscriber loop has increased the installation... Read

Some Basic Concepts of Fiber Optic Loss Testing
When testing loss in a fiber optic link, some basic principles must be kept in mind all the time. 1. The testing wavelength should always be the same as the working wavelength. Because optical fiber loss varies with light wavelength, you will get incorrect result if your measuring wavelength is different... Read

What is WDM (Wavelength Division Multiplexing) For Fiber Optic Communication? Fiber Optic Tutorial Series
What is WDM? WDM is the abbreviation for Wavelength Division Multiplexing. What it does is to split the the light in an optic fiber into a number of discrete wavelengths (colors). Each wavelength (color) is a independent channel running at data rate at 2.5Gbit/s, 10Gbit/s, 40Gbit/s or even 100Gbit/s (still under... Read

Everything You Need to Know About Fiber Optic Testing - Fiber Optic Technology Tutorial Series
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. These standards are part of EIA/TIA RS455 and are being... Read

An Introduction to ATM (Asynchronous Transfer Mode) Networks
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. ATM (Asynchronous Transfer Mode) has been proposed as an enabling network technology to support broadband integrated... Read

Introduction to SONET (Synchronous Optical Networking) - Fiber Optic Technologies Tutorial Series
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. SONET is sometimes described as "T-1 on steroids".... Read
