Optimization of NRZ data transmission at 10Gbit/s over G.652 fibre without in-line amplification
Karásek, Miroslav ; Radil, J. ; Boháč, L.
The best scheme of chromatic dispersion compensation, input powers to standard and dispersion compensating fibre have been analysed numerical with the aim to find limits of NRZ data transmission over G.652 fibre. Theoretical results have partly been verified experimentally.
Pump-controlled gain-locked Raman fibre amplifier
Karásek, Miroslav
Preliminary results of numerical simulation of pump-controlled, gain-locked Raman fibre amplifier have been presented. Numerical model of the gain-locked amplifier is based on interative solution of propagation equations for pumps, signals and spectral components of amplified spontaneous emission. Proportional-derivative feedback loop which controls the pump power has been implemented. Suppression of surviving channel power fluctuations due to channel addition/removal has been investigated.
Power transients in Raman fiber amplifiers
Karásek, Miroslav
Output power transient in Raman fibre amplifiers /RFA/ have been investigated both theoretically and experimentally. Large signal numerical model of RFA has been used for the analysis. It has been that substantial power transients can occur when WDM channels are dropped/added.
Transmission of packetized traffic over WDM through a cascade of EDFA's: experiment and simulation
Karásek, Miroslav
Transmission of burst-mode, packet data through a cascade of five erbium-doped fiber amplifiers is investigated experimetally and theoretically. Suppression of cros gain saturation in EDFAs by gain clamping the first EDFA has been studied.
Futher possibilities of optical amplification in the 1310nm wavelength range
Vojtěch, J. ; Karásek, Miroslav ; Radil, J.
Application of optical semiconductor amplifiers and distributed Raman amplifiers for distribution of 10GE signals at 1310nm has been studied experimentally.
Limits of 10 GE transmission using PC LAN adapters
Vojtěch, J. ; Karásek, Miroslav ; Radil, J.
In this contribution, we present experimental results on amplification of 10GE signále in the 1310nm wavelength range with respect to application of PC LAN adapters in metropolitan area networks.
Verification of applicability of PDFA in the 1310nm range
Vojtěch, J. ; Karásek, Miroslav ; Radil, J.
We present results of experiments aimed at increasing the reach of 1GE and 10GE transmission in the 1310nm wavelenght range by application of Praseof dimium doped fluoride fibre amplifiers.
