Jim Jachetta has compiled everything there is to know about Fiber Optics into 20 pages.
Whether you are a greenhorn or a professional, this will teach or refresh you on the topic of Fiber Optic Video Transmission. This guide is perfect at any level. First, we cover the basics. Then, we work up to the bleeding edge with 4K fiber optic video transmission. This guide is packed with practical examples. It provides the knowledge you need to become an expert quickly. Fiber Optic Video Transmission is regarded as low in latency and highly reliable. You may be exceedingly aware that Fiber Optics have trumped the speed of copper cable. You may also be aware that it provides unprecedented reliability that typical wireless setups cannot. Yet, it’s likely that you could use a refresher on the topic. The industry is moving fast. The applications of fiber optic video transmission are changing. It’s up to you to stay on top of it all. This user’s guide is the way to do that. We cover modern applications, end-to-end design, multiplexing, routing switchers, and the works!
Benefits of Fiber-Optic Video Transmission:
- Longer Distances
- Multiple Signals
- Noise Immunity
- Ease of Installation
- Connector Adaptability
- Ease of Splicing

Fiber Optic System
One of my favorite subjects is the transmission of video over fiber optic cable. I have had the pleasure of working on fiber optic implementations with Broadcasters to cover Presidential Elections and with Integrators on projects like the Las Vegas City Center.
Because of this passion, I am starting a multi-part series on the subject of Fiber Optic Video Transmission. My goal in writing this is to speak from my experience to make a topic that is scary to many, easy to understand and accessible so you can implement your own systems. I hope to do it in a humorous way relating my successes and challenges implementing many of these systems.
Anyone who knows me has also seen my passion for problem solving and doing the “impossible” and “never been done before”. I enjoy troubleshooting multi-million dollar fiber optic systems to discover a bad $20 patch cord or dirty fiber optic connector. The good news is that once a fiber optic system is up and running I know you will get many years of reliable operation.
In this series I will start with the basics and work my way up to the bleeding edge with 4K video fiber optic transmission. The series is perfect for the beginner and a good review for the expert. Clink these links to go to my first posts:
I’ve had a great time putting this series on Fiber Optic Video Transmission together for you and I hope you get great insight and some practical tips for your particular situation.

Fiber optics is a method of carrying information using optical fibers. An optical fiber is a thin strand of glass or plastic that serves as the transmission medium over which information is sent. It thus fills the same basic function as a copper cable carrying a telephone conversation, computer data, or video. Unlike the copper cable, however, the optical fiber carries light instead of electrons. In so doing, it offers many distinct advantages that make it the transmission medium of choice for applications ranging from telephone calls, television, and machine control.
The basic fiber-optic system is a link connecting two electronic circuits. Figure 1 shows a simple fiber-optic link.
There are three basic parts to a fiber-optic system:
• Transmitter: The transmitter unit converts an electrical signal to an optical signal. The light source is typically a light-emitting diode, LED, or a laser diode. The light source performs the actual conversion from an electrical signal to an optical signal. The driving circuit for the light source changes the electrical signal into the driving current.
• Fiber-optic cable: The fiber-optic cable is the trans- mission medium for carrying the light. The cable includes the optical fibers in their protective jacket.
• Receiver: The receiver accepts the light or photons and converts them back into an electrical signal. In most cases, the resulting electrical signal is identical to the original signal fed into the transmitter. There are two basic sections of a receiver. First is the detector that converts the optical signal back into an electrical signal. The second section is the output circuit, which reshapes and rebuilds the original signal before passing it to the output.
Depending on the application, the transmitter and receiver circuitry can be very simple or quite complex. Other components that make up a fiber-optic trans- mission system, such as couplers, multiplexers, optical amplifiers, and optical switches, provide the means for building more complex links and communications networks. The transmitter, fiber, and receiver, how- ever, are the basic elements in every fiber-optic system.
Beyond the simple link, the fiber-optic medium is the fundamental building block for optical communications. Most electrical signals can be transported optically. Many optical components have been invented to permit signals to be processed optically without electrical conversion. Indeed, one goal of optical communications is to be able to operate entirely in the optical domain from system end to end.
