How Do Fiber Optic Cleavers Precisely Cut Optical Fibers in a Flash? :: What is optical fiber cleaving Simply put, optical fiber cleaving is the art of cutting glass optical fibers at a perfect 90° angle with a mirror like surface Dummies' Guide to Fiber Optic Bit Error Ratio (BER) Measurement Bit error ratio (BER) measurement is the fundamental measurement of the quality of the fiber optic communication system It measures the system's probability that transmitted bits will be correctly received as logic ones and zeros 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 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 Dummies' Guide to Fiber Optic Sensors What are fiber optic sensors The fundamental characteristic of all fiber optic sensors is that they depend on some optical properties, such as intensity, phase, state of polarization and wavelength, to be modulated by measurands Everything You Need to Know About Fiber Optic Ethernet In the last decade, a wide variety of applications have been developed that covers a dozen of datacom networking technologies The transmission speed ranges from 10Mbits up to 10Gbit/s and growing 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 What Are Fiber Optic Attenuators? Fiber Optic Communication Tutorial Series Why Do We Need Fiber Optic Attenuators A fiber optic attenuator, also called an optical attenuator, simulates the loss the would be caused by a long length of fiber The Current Status of FTTH in the US and the Rest of the World Understanding FTTH (Fiber To The Home) FTTH is an all-fiber connection to the home which provides a minimum of 155Mbps bandwidth on both up stream and down stream directions Basically, it is composed of a fiber from the service node to the optical splitter, the optical splitter which separates to (fan out) terminate on single home ONU Understanding The Basics Of All Optical Switching What is all-optical switching All-optical switching is a process by which light, usually in the form of digital communication signals, is routed from one transmission channel to another, or modulated, without intermediate conversion to another format What Are Fiber Optic Circulators? Fiber Optic Communication Tutorial Series What is an optical circulator The optical circulator has similar function and design as the optical isolator What Are Fiber Optic Isolators? Fiber Optic Communication Tutorial Series Why do we need fiber optic isolator Light can be reflected back and forth 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 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 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 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 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 The Future of Fiber Optic Communication There is no question that fiber optic communication is our future Fiber optic communication industry has been enjoying amazing growth for over 15 years Troubleshooting Your Optical Fiber Networks: Introduction to OTDR – Optical Time Domain Reflectometer 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 Optical Fiber Fusion Splicing and Its Applications What is optical fiber fusion splicing Optical fiber fusion splicing is a welded joint formed between two optical fibers Understanding Basic Terms in Indoor Fiber Optic Cable Installation 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 Everything You Need To Know About Aerial Fiber Optic Cable Installation 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 The Tremendous Applications of Fiber Optics The use of fiber optic systems is expanding at a amazing rate Only in the past 10 years, fiber optic communications systems have replaced almost all coaxial and twisted pair cables especially in network backbones What Is Structured Cabling For Computer LAN Networks? :: What is structured cabling Modern computer LAN (local area network) wiring has the concept of structured cabling The Story Of Legacy Fiber Optic Connectors :: Choices of connectors Over the years, a large variety of fiber optic connectors have been designed for most fiber optic installations Lightwave equipment manufacturers have never standardized on any one connector type, they actually provide a selection of connectors for their equipment interface Everything You Need To Know About Computer LAN (Local Area Network) Backbone Wiring :: The Definition of Backbone Cabling Backbone cabling may be within one building or between buildings on a campus All wiring between telecommunication rooms is called as backbone cabling The Secret Of A Successful Underground Fiber Optic Cable Installation The two most common outdoor fiber optic cable installations are pole line aerial installation and underground cable installation Underground cable installation can be buried directly underground or placed into a buried duct How To Install Outdoor Fiber Optic Cables In Underground Ducts And Innerducts :: Duct/Innerduct materials and colors: Fiber ducts are usually made from HDPE (high-density polyethylene), PVC or other compound They are usually in black or gray FAQ On Fiber Optic Cable Handling And Installation :: 1 What is the difference between copper cable and fiber optic cable What Are OFNP, OFNR, OFNG And OFCG? Understanding Fiber Optic Cable Fire Ratings Just like copper cables, NEC (National Electrical Code) requires indoor fiber optic cables be marked with their fire and smoking ratings NEC requires all indoor fiber cables be marked correctly and installed properly for its intended use How Do Fiber Optic Couplers Work And How Are They Made? :: The need for fiber optic couplers We use electronic couplers all the time: such as a telephone coupler which lets you connect both a telephone and a fax machine to the same telephone line Or a CATV coupler which lets you connect several TV sets to a single cable from Comcast What Are Optical Fiber Amplifiers And How Do They Work? :: Why do we need optical fiber amplifiers Basically what the optical fiber amplifiers solve is the traditional distance problem as in any long distance telecommunication system such as a trans-Atlantic link
