B.I.Stepanov Institute of Physics of the National Academy of Sciences of Belarus offers consumers National etalon for polarization mode dispersion unit in optical fiber under a manufacturing agreement and is looking for partners interested in a distribution services agreement.

B.I.Stepanov Institute of Physics of the National Academy of Sciences of Belarus manufactures a National etalon for polarization mode dispersion unit in optical fiber designed to ensure the uniformity of measurements of the polarization mode dispersion (PMD) in the range from 0.005 to 120.0 ps, storing the size of the PMD unit in optical fiber, reproducing and transmitting the specified unit value to lower-level references and high-precision operating measuring tools (MT).

Functionally, the etalon consists of:
* a complex of measuring instruments for reproducing a unit of PMD by the polarimetric method, designed to reproduce and store the size of a PMD unit during its operation as part of a standard;
* a complex of measuring instruments for reproducing the unit of PMD by the interferometric method, designed to reproduce and store the size of the PMD unit during its operation as part of the standard;
* environmental monitoring device;
* control systems, registration and processing of measurement results based on a personal computer (PC) with special software.

Principle of operation of the PMD unit etalon in an optical fiber based on the polarimetric method is based on the determination of the Jones matrix linking the parameters of the state of polarization of radiation at the input and output of the object under study (comparator-simulator). The state of polarization of radiation is described using the parameters of the Stokes vector.

Principle of operation of the PMD unit etalon in an optical fiber based on the interferometric method is based on the measurement of the time delay between orthogonally polarized modes of radiation, introduced by the birefringent medium, using the interferometric method. This method is an indirect method of PMD measurements in optical fibers, based on the analysis of the radiation of a broadband source, which has passed the specified medium, using an interferometer.

The economic efficiency of the development is due to:
* combination of etalon tools in accordance with the state verification scheme into a unique national etalon with optimization of the number of links in the verification scheme;
* increasing the accuracy of transmitting the PMD unit in the lines and elements of fiber-optic systems for transmission of
information (FOTS);
* creation of a system of metrological support for PMD measurements in high-speed FOTS with spectral compaction;
* possibility of upgrading of the existing FOTS in order to increase the capacity of communication lines.

Application areas:
* information and communication technologies;
* communication, optoelectronics and optical systems;
* national security and defense;
* construction, installation and commissioning of fiber-optic communication lines;
* protection of the population and territories from emergency situations.

B.I.Stepanov Institute of Physics offers partners:
* National etalon for polarization mode dispersion unit in optical fiber under a manufacturing agreement;
* National etalon for polarization mode dispersion unit in optical fiber under a distribution services agreement.

The National etalon for polarization mode dispersion unit in optical fiber has metrological characteristics that meet the requirements of international standards, and the accuracy characteristics of the etalon are 1.5 times better than those of the GET 185-2021 etalon created at «VNIIOFI» (Russian Federation).

The cost of calibration (verification) on the created etalon is much lower than the cost of calibration (verification) of one unit of these means at «VNIIOFI» (Moscow city), which makes it possible to certify most measuring instruments at significantly lower costs.

The National etalon was approved by the resolution of the State Standard № 44 dated 02.08.2019 in accordance with the interstate standard GOST 8.607-2012.
