Development of a cable of 3000 fibers, using tapes of 16 fibers.
The design and characteristics of cables with 3000 optical fibers are described. In a design tape from 16 fibers that can be used are used. easily divided into 4 types of 4 fibers or 2 of 8. Each. Field tests of cables with diameters of 44 and 46 mm showed good performance. The design of a device for splicing by the method of fusion and separation of fiber tapes is presented. The aim of this proposal is to: increase the number of fibers in the cable and reduce the connection time of the cables.
Foa certification
Optical LZ with AC delayed.
Optical LZ with altern. delayed. In the 1st embodiment, an optical circulator with 4 ports is used, one of which is used as an input, others as an output, and the optical fibers with Bragg reflector arrays with a linearly varying period are attached to the remaining 2, and the nature change in the period in both cases is the opposite to compensate for variance. In the 2nd case, a communication device with radiation separation according to the polarization state is connected to the port of the optical circulator, and 2 segments of the optical fiber with arrays of Bragg reflectors with ac are connected to the outputs of the communication device. period. In the 3rd case, quarter-wave plates are located at the input of the optical fiber segments. In each case, a delay change is made using linear fiber expansion.
Linear control of the spectral characteristics of components with wavelength selection.
The design of linearly tunable fiber-film components whose characteristics depend on the wavelength of the incoming radiation is considered. The design includes a linearly broadened thin-film optical waveguide with a high refractive index associated with a single-mode fiber coupler. The results of the theory are given. and experiment. studies of linear adjustment of spectral characteristics (branch power, resonance position and polarization of the light emerging from the fiber). Almost linear control has been achieved.
