Stimulated Brillouin scattering in DWDM all optical communication systems
TLDR
This work on the introduction deals with phenomena affecting the signal transmission in optical fibers, and the main idea is impact of SBS at fully WDM optical communication systems, namely DWDM.
FREE SPACE OPTICS EXPERIMENTAL SYSTEM - LONG TERM MEASUREMENTS AND ANALYSIS
TLDR
A device which measures all mentioned weather indicators such as a fog density, a relative humidity and a temperature is introduced, based on measured data, which evaluates weather conditions for Kosice in terms of FSO operation.
On Mitigation of Four-Wave Mixing in High Capacity Ultra-DWDM System
TLDR
A strategy to mitigate the impact of FWM on optical signal transmission in a DQPSK modulated 32-channel Ultra-DWDM system with 1.28 Tbps (40 Gbps per channel) transmission capacity is proposed.
Fog density measuring system
TLDR
This paper deals in detail with a description of the instrument for measuring the density of fog, humidity and temperature of the environment and how long-term measurement allows us to create models for transmission FSO environment.
VIDEO SURVEILLANCE SYSTEMS
TLDR
Object modelling, activity analysis and change detection for video surveillance systems to detect, track and classify targets and the design of the video surveillance system is described.
Effects act on transmitted signal in a fully optical fiber WDM systems
This article is devoted to influences in optical fibers. The main impact on quality of transmission signals have nonlinear phenomena. Their formation it isn't accidental. Very important position has
LABORATORY EQUIPMENT TYPE FIBER OPTIC REFRACTOMETER
Using fiber optics and micro optics technologies we designed innovative fiber optic index of refraction transducer that has unique properties. On the base of this transducer a laboratory equipment
Deployment of the PON with an optical fibre G-652.B
TLDR
Comparisons of the difference between simulated and measured parameters of optical networks are compared and demonstration when it is better to use an optical splitter, and when it are better to connect the fibre directly is demonstrated.
Analisys of the Methods of Preventing of Contention Resolution in Optical Packet Switching Networks
Optical networks evolve fast. Nowadays many technologies of optical networks are using. But there are some restrictions which make limited of the possibilities of the optical networks. Contention
