What Is Fiber-Optic TV?

December 10, 2011

Fiber-optic TV refers to television programming delivered through a fiber-optic network of cables, rather than antenna, satellite or cable transmissions. Fiber-optic cables consist of strands of glass the breadth of a human hair that carry digital signals along the length of the transmission line. Also known as optical fibers, hundreds of these finely spun glass fibers are bundled together within a protective sheath and transmit television program information through pulses of light. Fiber-optic TV requires the use of a special receiver, similar to cable TV, to interpret the signals from the optical cable and translate them into images on a customer's TV. Advantages of fiber-optic information transmission are many, including less expensive components, faster transmission speeds and clearer reception.

How Do I Choose the Best Fiber-Optic Modem?

December 10, 2011

Choosing the best fiber-optic modem depends on a few factors, including availability, usability and cost. A modem connects an electronic device such as a computer to a network or the Internet. Fiber-optics offer a strong, fast connection that is more efficient than copper wiring or coaxial cables, which are commonly used for home Internet service.

What Is a Fiber-Optic Cable Assembly?

December 10, 2011

A fiber-optic cable assembly is a collection of parts that includes an optical cable with special connectors on each end. Fiber optics deals with the uses and properties of light, usually of specific wavelength. The optical cable has an inner core that is usually very thin, and is made by drawing molten glass thinly and allowed to solidify in steam, making the resulting cable slightly flexible enough to be rolled. It also has an outer jacket to protect the cable. The fiber optic cable may be used for high-speed data communications, special lighting requirements, and medical applications.

What Is a Fiber-Optic Network?

December 10, 2011

A fiber-optic network is a computer-to-computer or computer-to-Internet network created using fiber-optic cables. These cables are made of thin strands of glass that transmit light. Computer information is converted into light pulses to send across the cables and is converted back into regular data when it reaches its destination.

What Is a Fiber-Optic Endoscope?

December 10, 2011

A fiber-optic endoscope is a medical imaging device that a medical professional can insert into a patient's body to get a clear view of the inside. It has one bundle of fiber-optics that provide sufficient lighting in the body and another bundle that carries the image either to the video monitor or into an eyepiece. There are rigid and flexible endoscopes, which are used for different medical procedures. Some endoscopes have small tools attached to them, such as forceps, scissors and baskets. These tools allow the physician to perform a minor surgery, remove a sample tissue for testing or spot internal bleeding, tumors, hernias and other medical problems.

What Is a Fiber-Optic Router?

December 10, 2011

A fiber-optic router is a router that uses fiber-optic cable to transport a data signal. It is much faster than any other type of router, but is more expensive. These routers are most often used in larger offices or institutions, as well as across the Internet.
