Fiber Optic Internet For CATV Optical Transmitter - People use internet for purposes of communication. Internet carries a large array of information via planet broad Web. New methods of communicating have been enabled and accelerated by internet like immediate messaging and electronic mail. Other types of communicating like social networking and internet forums have also been enabled. One can connect to internet using various methods like dietary fiber optic internet, DSL and ADSL.

Different varieties of Optical Fiber Pigtail

June 23, 2011

Different varieties of Optical Fiber Pigtail With a root fiber into both the mount plug called Optical Fiber Patchcord.Optical Fiber Pigtail is special case of Optical Fiber Patchcord, namely the end only in optical fiber with plugs. In engineering and instrumentation, extensive use of various types, specifications of jumpers, the jumper in the ends of the fiber is of the same model can plug, also can be different models. Jump line can be single core, also can be more core. The price jump line mainly by joint quality decided. Therefore the price also differs greatly. In selecting jumpers, in line with cheap to choose is nice, but must not buy inferior quality low price products.

Fiber-optic cable development in China Fiber optic cable is a communication cable, consists of two or more glass or plastic fiber core composition, the fiber core in the protective cover layer, covered by a plastic PVC outer casing. Within the optical fiber along the general use of infrared signal transmission.

How Does a Cable TV Splitter Work?

June 23, 2011

How Does a Cable TV Splitter Work? A cable TV splitter is a device that is built to provide multiple outlets for one signal. There are many variations of splitters, ranging from a simple two-way CATV splitter to a mighty 16-way splitter. Today's splitters are built to retain a signal's strength without any modulation loss. To have the best picture quality for high definition television units, you have to have a strong signal.

How to Use a Field Strength Meter

How to Use a Field Strength Meter Place the field strength meter in a horizontal position and turn it on to maximum sensitivity level. Different models have a different way of indicating the maximum level, so make sure you have turned your field strength meter to its maximum sensitivity.

OTDR stands for optical time domain reflectometer

June 22, 2011

OTDR stands for optical time domain reflectometer OTDR stands for optical time domain reflectometer, and can be an optoelectronic instrument that is employed to characterize specific optical fibers. This tool injects optical pulses in series into fibers for screening along with extracting lighting form that fiber that is reflected back again from points in that specific fiber where the refraction changes. The strength of return pulses are then measured in time and then plotted below a function of the fiber length.
