Distance education is changing as the capabilities offered by electronic technology expand. The distant learner is no longer isolated from the educational source by geographic barriers. Two-way interaction between teacher and student is now possible through bound and unbound media. A common method of delivering distance education is satellite transmission. Satellite networks provide one-way video transmission augmented with two-way audio transmission via telephone connections.

Optical fibers are frequently used in data transmission systems, Because of their ability to transmit large amounts of information and dielectric nature. In central, metropolitan, or broad-area applications, network topologies incorporating many wavelengths per optical fiber are utilized to connect thousands of users with a wide variety of transmission rates and capacities. The simultaneous transmission of many wavelengths over a fiber with a nm range of 1300 to 1600 is a potent characteristic of an Optical communication network.

Abstract:

Currently, developments of the so-called Smart-constructions are relevant as they enable a real-time monitoring of changes in required values. Smart designs are widely used in the construction, automotive and aerospace industries. Technologies of creating products from polymer composite materials make it possible to introduce various sensors directly into the structure of a material, thereby create systems monitoring the state of structures. The most recommended for such implementation are fiber-optic sensors, which have a number of advantages over other sensors (luminescent, strain gauge, pie

Abstract:

Erbium-doped fiber source for Fiber Optic Gyro (FOG) uses doped fiber to produce super fluorescence with laser pumping. It has higher output power, wide spectral lines, lower temporal coherence, good temperature stability and long life, which are perfect source for high precision FOG. To solve the problem of reliability analysis of erbium-doped fiber source for FOG with zero failure data, Weibull distribution is chosen as the life distribution model of erbium-doped fiber source on basis of the failure mechanism analysis in this paper. And Bayesian theory is used to estimate the failure rate in

Abstract:

<strong>ABSTRACT</strong> Over time, optical telecommunication network cables experience power loss due to micro inflammations on the core of optical fiber cable lines. These inflammations are usually very small and cannot be detected by physical inspection. However, they constitute a prominent source of optical power loss irrespective of size. This mechanically induced loss effect is investigated in the bid to reduce optical power loss by using an optical approach. The factors inducing the power loss are majorly the joining of fiber optic cable lines as well as the perturbations arising from

Abstract A conductor thermal model related to CIGRE and IEEE solutions was developed and compared with measurements. Two pylons of a single line were equipped with weather monitoring stations and conductor temperature sensors based on Surface Acoustic Wave (SAW) principle. Also a fiber optic distributed temperature sensing system was installed to provide additional data. Over 2.5 million data points were evaluated. Developed model deviation for more than 99 % of values proved to be ±1 °C for SAW sensor and ±3.5 °C for the fiber optic measurement. Several ampacity determination methods were des

Abstract:

We have shown the opportunity to use the unique inhomogeneities of the internal structure of an optical fiber waveguide for remote authentication of users or an optic fiber line. Optical time domain reflectometry (OTDR) is demonstrated to be applicable to observing unclonable backscattered signal patterns at distances of tens of kilometers. The physical nature of the detected patterns was explained, and their characteristic spatial periods were investigated. The patterns are due to the refractive index fluctuations of a standard telecommunication fiber. We have experimentally verified that the
