Fiber optic technology is still underutilized, even though it represents the cutting edge in connectivity. Seeking Alpha, a technology market news source, reported that only 11% of Internet connections use fiber optics. Cloud computing is one area of opportunity for fiber optic connectivity.
SCADA (Supervisory Control and Data Acquisition) networks have undergone significant changes, and the technological developments have made fiber optic technology a viable solution for users looking to build a network.
Supervisory control and data acquisition (SCADA) is a control system architecture consists of several computers, connected through networked data communications and graphical user interfaces for high-level supervision of machines and processes. SCADA system also covers sensors and other devices, such as programmable logic controllers, which interface with process plant or machinery.
Security and surveillance cameras are all around us. Look around and you will find them in virtually every place you go. Some common applications include:
Fiber optic cables manufactured in a production unit need to undergo several mechanical tests to ensure their suitability to use in outdoor environment. While some tests are intended to assure the capability to use in outdoor environment, there are some tests that assure their suitability with the installation machines used for deployment. Sheave test is one of such tests. Sheave test is a kind of mechanical test which tests the strength of cable and its sheath to withstand the repeated movements through the sheaves.
Steel tapes are used for corrugation of fiber optic cables to provide extra mechanical strength to the fiber optic cables that is required for some installation conditions. ECCS tape or Electrolytically Chrome Coated Steel tape or Stainless Steel tapes comes in rolls of 1 or 2 kilometers in length. But fiber optic cable lengths during production are usually in lengths of 2, 4 or 6 kilometers.
Fiber optic cables installed near to the high voltage power cables are exposed to effects such as Tracking, Dry band arcing, Corona effect and Flashover. This article is an attempt to deal with such effects on fiber optic cables. Generally when we talk about the advantageous of fiber optic cables over other metallic media for telecommunications, we say optical fiber cables are free from electro-magnetic influences. That is true as far as the communication signals are concerned.
Laser is an abbreviated form of ”Light Amplification by the Stimulated Emission of Radiation”. A laser is a device that produces optical radiation by the process of optical amplification based on the stimulated emission of electromagnetic readiation. Laser was developed in 1960. Invention of Laser is one of the major milestones in the history of fiber optic communication. Theodore H. Maiman at Hughes Laboratory invented the first Laser, based on teh theoretical work by Charles Hard Townes and Arthur Leonard Schawlow.
Writing specifications and stressing on the properties of the material that shall be used in the construction of fiber optic cables need a lot of technical knowledge about materials, cable and their test methods. For most of the staffs working with cable buyers, this task is troublesome and usually, they look for similar specifications.
