Theor developed. model of a polarization rotator based on the bending of a semiconductor waveguide. In constructing the model, completely vector wave equations and the theory of coupled modes were used. Calculations based on this model are confirmed by previously published experimental data. It was found that the sensitivity of the device substantially depends on the geometry of the waveguide. Designed polarization rotator m. used in systems with spectral multiplexing.
The first domestic optical cable built into a ground wire
ZAO Samara Optical Cable Company has developed and received a certificate for optical cables embedded in the lightning protection cable of the power transmission line, OKGT-MT brand.
Optical communication cable.
In the center of the optical cable of a circular cross-section of the proposed structure, there passes a power element made of strong plastic, also of circular cross-section, reinforced with steel wires or threads of heavy-duty plastic. The outer diameter of the power element m. from 2 to 20 mm. Optim. value for most cases lies in the range. 5-10 mm. The power element serves to absorb the tensile forces of the cable, unloading, to a large extent, optical fibers from their effects. A trapezoidal cordel is wound on it with a given step. Between its turns with the same step, but with resp. a shift, optical fibers are wound. If necessary, the composition of the cable m. supplemented with 1 or 2 isolated metal. signal cores.

About marking optical communication cables
Designations of optical communication cables manufactured by domestic manufacturers are presented. The problems that arise during decoding of cable marking are considered.
Optical Cable Testing for Gigabit Ethernet
The loose - LX standard for transmitting light radiation with a wavelength of 850 and 1310 nm through single and multimode optical cables is considered. The characteristics of the standards for Gigabit Ethernet and the requirements for a field tester for certification of FOCL according to these standards are given.
