The article is devoted to the consideration of the possibility of using the chirp function of optical pulses as a resource for radio segment control in RoF-systems. Such a resource does not belong to the traditional telecommunication resource, is realized at the physical level and is characterized by high speed. The scheme of RoF-segment construction is proposed - using the developed components: the converter «Chirp To Amplitude» and interference splitter. In the case when the antenna array forms a spatial separation of VLANs, it is shown that the parameter of payload of device interfaces improves in relation to the VLANs traditionally formed on the radio segment.
Optical Reflectometer (OTDR-Optical Time Domain Reflectometr) of various types are widely used in almost all stages of the fiber-optic communication systems, from production of fiber optic cable to the construction of fiber-optic communication lines and their operation. OTDR provides a quick and easy diagnosis of the state of fibers, cables and fiber-optic communication lines in general. A new method of analysis allowing visually detect traces of welding with low loss.
